The battery voltage is checked in the battery module for undervoltage and overvoltage.

New batteries have a too high voltage which causes the overvoltage limit to be exceeded.

Solution:

With the FBox 'PCD3.BAT0', selectable from the ‘System information’ family it is possible to switch off the overvoltage limit check on the battery module to prevent the battery LED from being switched on and the battery error message in the application program from being activated if the battery voltage is above the overvoltage limit.

The battery voltage check is performed in the battery module and the changes made by the FBox 'PCD3.BAT0' are stored in the battery module and not in the PCD3.M5/6, PCD2.M45xx.

As all information concerning the overvoltage limit check are stored in the battery module, it is possible to make the modifications in one PCD 'A' and after the modification, to insert the battery module in another PCD 'B'.

Battery modules with hardware version < C have a factory default battery undervoltage and overvoltage check.

Battery modules with hardware version >= C have the battery undervoltage test function ex works.
The battery overvoltage is not checked.

After the FBox 'PCD3.BAT0' has deactivated the overvoltage limit check, modification 8 is activated on the battery module.

Picture shows a battery module with hardware version A and modification 1 and 3

The modification number is displayed also on PG5 Online configurator, hardware information.

After the usage of the FBox 'PCD3.BAT0' the following information is visible on the PG5 hardware information. (Modification 8 was added)

Modification number 8 is only activated for this purpose 'Overvoltage limit check disabled'.

After changes have been made with the FBox 'PCD3.BAT0', the 24VDC power supply to the PCD must be switched off and on again so that the changes relating to the battery LED, battery error message in the application program and the update of the modification number in the hardware information can be adopted.

More information are available on the online FBox help.

Overview battery module hardware version, modification, under- and overvoltage test.

The FBox library ‘SBC Maintenance’ which includes the 'PCD3.BAT0' FBox can be loaded from this FAQ, over the PG5 update manager and will be installed automatically with newer PG5 versions.

No, SBC devices are not affected from the Ripple20 zero-day vulnerabilities since none of our products uses the TCP/IP software library developed by Treck, Inc.

The device configurator gives an error when a card with 16 digital inputs or outputs is configured on base address 240 because the address 255 is reserved for the hardware watchdog!

Can I use the I/O card on this slot?
Whether the media mapping is configured or not, it is possible to put a 16 I/O card on address 240. The only condition is that the last I/O of the card (address 255) isn't used! The message "On the defined module, the last input/output with address 255 cannot be used." can be ignored for digital I/O modules (but not for analogue I/O modules)

Remark
It is planned to change the error message of the device configurator.

Please read this FAQ in case you are updating the PCD firmware from a version previous to 1.16.xx to 1.16.xx (e.g. from 1.14.23 to 1.16.16).

When updating the firmware of the PCD from a version to 1.14.xx (or previous) to version 1.16.xx the content of the memory is lost (user program, hardware configuration, register, flags etc. and the user program backup on the onboard flash).

Reason
The reason for this data loss is that the onboard flash (where the user program backup is stored) is reformatted in order to support the new backup mechanism which also does backup the confiugration of the IP Enhancements (DHCP, DNS, PPP, FTP- and Web server).
Reformatting the flash takes up to one minute right after the download of the new firmware.

• In order to avoid the loss of any data, please "upload all" before updating the firmware (for that you can "download all" after updating the firmware.
  
• Note that you'll need the USB port after the update (as your S-Bus address might be gone).
  Alternatively, you can also copy the user program to flash and upload the content of the media before the update (e.g. with the "Quick Data Transfer).
  
• In this case the program and the hardware configuration will be restored from flash after updating the firmware (for going online and downloading the media content after the FW update).

Additional remarks for PCD3 hardware bought some time ago
PCD3 systems with hardware older than "D" (and PCD3.M3020 and PCD3.M3120 with hardware older than E48) can not be updated to firmware version 1.14.xx and newer because these platforms are not equipped with enough memory to hold the firmware 1.14.xx (or 1.16.xx).
In case a FW 1.14.xx or more recent is loaded to one of these systems, the PCD will remain in the boot loader state after the download of the FW (in this state, a 1.10.xx can be loaded again).

All PCD1.M2 and PCD2.M5 systems can be equipped with a firmware 1.16. and more recent.

Firmware versions before the version 1.10.51 were not supporting retries during the "Upload/Merge" process of the BACnet configurator. In case a telegram got lost during upload of the BACnet configuration (from the PCD to the PC) the transfer was been aborted.

Symptom
During an Upload (for the function "Upload/Merge" of the BACnet configurator) all of the sudden the transfer of the configuration stops. This phenomenon is observed when a telegram is lost. This telegram loss is random, dependent on the network load.

Reason
Firmware versions before the version 1.10.51 were expecting a communication without telegram losses. In case a telegram was lost (due to network problems) the transfer was interrupted by the PCD firmware. Because of the interruption the BACnet firmware was not notified, but it remained in a state of waiting for the completion of the upload process.

Solution
The firmware version 1.10.51 (for the PCD3 or the PCD2.M5) together with the BACnet firmware 1.10.50 are more robust and can cope with telegram losses during the upload of the BACnet configuration. Please update the firmware of your PCD and the one on your PCD7.R56x to the mentioned (or later) firmware versions.

Remark
Please note that the firmware version of both, he PCD and the BACnet module must be updated.

With the Device Configurator it is possible to configure the hardware and calculate the power consumption of the modules. Before we had an Excel sheet to calculate the power consumtion.

Problem
A configuration calculated with the old Excel sheet did not have the same current limitation for the CPUs. The same configuration is maybe rejected by the Device Configurator.

Reason
The reason is, that the maximal current on the V+ is depending on the charge on the 5V power supply. The Excel sheet did not take care of this dependency. This was leading to problems in very few cases. In the Device Configurator this dependency is added to the calculation. Means that each module that charges the 5V, has as well an influence on the maximal current on the V+. Due to this reason a configuration that was declared with the old Excel sheet as o.k can now fail, when configuring it with the Device Configurator.

Solution
We recommend using the Device Configurator. If you are very close to the limit it can be sufficient to have a better power supply. If your power supply has a tolerance of -10/+10% this could be enough to guarantee the configuration to work. More informations about different Power Supplys can be fount in the PCD3 manual chapter 3.2

Some Ethernet devices do generate gratuitous ARP telegrams every time they are connected to an Ethernet network. This telegram informs the router that there is a new IP address on the network and causes it to update its internal MAC addresses table in case the according IP was already mapped to a MAC address.

Background
If a device is replaced on a network and the new device does have the same IP address, it won't be reachable until the router (or other devices that communicate with the replaced system) refreshes the MAC address table.
The gratuitous ARP telegrams are one way to inform a router about a modification of the MAC address bound to an IP address.

Does a PCD generate gratuitous ARP telegrams?
No, a PCD (e.g. a PCD3, a PCD2.M5xxx or a PCD equipped with a PCD7.F655) does not generate gratuitous ARP telegrams when being connected to an Ethernet network (when it gets a "Link"). This feature is not implemented in the stack, and there are no plans for implementing this feature into the stack of the F655 because:

• there is a relatively easy to realize workaround available
• and the gratuitous ARP telegram is only required in case PCD is being replaced (which is not very often)

How to cause the router to update its MAC address?
Instead of relying on a gratuitous ARP telegram, a simple telegram can be sent to the router device every time the link is being detected (indicated by a rising edge of the "Diagnostic Flag+6", or as in the attached code example just regularly every 60 seconds). The telegram to be sent can be done by using the Open Data mode of the PCD.
Attached you can find a small code example which could be used on a PCD3 or a PCD2.M5xx0 (given no other ODM code is implemented on the system). This code can be added to a CPU in PG5 1.4.300 project using the "Add files..." (from the context menu of the "Program Files" folder of the CPU). Additionally, plase update the symbol "RemoteIP" within this file to a fitting IP address on you network and read the header of the file for more information how to work with this code. 

Is it possible to order the battery module cover (PCD3.M5xxx) and the I/O covers as spare parts?

Yes, it is possible ordering these covers separately with the article numbers below:

• I/O cover (protection if no modul is plugged on a slot): order number 4 104 7515 0
• Battery modul cover for PCD3.M5xxx or PCD3.M6xxx : order number 4 104 7493 0

After a succesful download the PCD3 or the PCD2.M5xx0 doesn't go in run. It stays in HALT in XOB 16.

Symptom
The download option "RUN Program after succesful download" is activated. With a specific project, the CPU doesn't go in RUN. It can be started manually without problems. The installed PCD3 firmware is 1.08.23 (1.08.19 for PCD2.M5xx0 or 1.08.21 for PCD2.M480).

Reason
Due to a firmware problem, the CPU goes not in RUN if the project has a specific (big) size. The PCD3 and PCD2.M5xxx and PCD2.M480 CPU's with firmware version <=1.08.23 are concerned.

Solution
Please update the firmware of your

• PCD2.M480 to 1.08.53 or later
• PCD2.M5xx0 to 1.10.16 or later
• PCD3.Mxxx0 to 1.10.16 or later

The firmeware can be downloaded from the support site (the first firmware with the correction is 1.08.31).

Changing the Profi S-Bus settings puts the CPU in HALT with a BUS Error

Problem
If there is a Profi S-Bus configuration already running on a PCD3 and some settings in the "Hardware Settings" are changed. Per example check / uncheck PGU, the CPU goes in HALT with a Bus Error after the download.

Reason
This problem is related to a problem in the firmware

Solution
The next official firmware >03C will correct this problem. As workaround the PCD3 has to be restarted after the download of the new "Hardware Settings".

On the PCD3.M5340 the bus termination can be activated in the PG5 Hardware Settings. A relay is switching the termination on or off.

While the serial PGU port of systems before the PCD3 did always work as PGU port when connecting a PCD8.K111, the serial PGU port of the PCD3 can be configured for using a modem. If this is done, it is no longer possible attaching a PCD8.K111 and establishing a PGU connection.

Symptom
It is not possible going online with the PGU communication mode using a PCD8.K111 programming cable plugged in on the D-SUB labeled "Com/PGU" of a PCD3.M5xx0.

Reason
The port "Com/PGU" of the PCD3.M5xx0 can be used as either PGU port for programming the PCD or for connecting an external modem to the PCD3. In case a modem is connected, the full handshake must be enabled and by doing so the detection mechanism for a PGU connection established with a PCD8.K111 is disabled.
A second reason could be that the firmware 039 is installed on the PCD3. In this case a firmware problem avoids a successful serial PGU connection.

Solution
Connect to the PCD using a USB cable (which always works as programming connection) and upload the current hardware settings of your PCD3.
§ix100519§
After having uploaded the current configuration of the PCD3, check that the checkbox "Full RS232-handshaking on Port 0" is not checked. If it is checked, uncheck it and download the modified hardware configuration in order beeing able going online with a "serial PGU" connection.

If it is still not possible going online with the PCD3, please check the firmware version of the PCD3. Note that the version 039 has a known problem that avoids going online over the Serial PGU connection. In case you are concerned by this problem, please contact your local sales office and request a firmware that fixes this problem (e.g. 03A).

Explanations of what kind of external devices you need to establish a VPN. This feature is explained in

the example with BacNet.

The PCD1.M110, PCS1 and PCD3 are equipped with a supercap. This supercap needs a certain time until it is fully charged.

PCD1.M110/120
It takes about 30min. until the supercap is fully charged (5T). To keep the RAM content at least 2V are needed. The supercap contains 2V after about 5min. After this time the PCD1 will keep the data in RAM for a short time. The  buffer time (30 days for PCD1.M110 and 7 days for PCD1.M120) can only be guaranteed if the supercap is fully charged, that means after at least 30 minutes runtime.

PCS1
It takes about 45min. until the supercap is fully charged (5T). To keep the RAM content at least 2V are needed. The supercap contains 2V after about 6min. After this time the PCS1 will keep the data in RAM for a short time. The full buffer time (5..15 days) can only be guaranteed if the supercap is fully charged, that means after at least 45 minutes runtime.

PCD3
It takes about 6min. until the supercap is fully charged (5T). To keep the RAM content at least 2V are needed. The supercap contains 2V after about 1.5min. After this time the PCD3 will keep the data in RAM for a short time. The full buffer time can only be guaranteed if the supercap is fully charged, that means after at least 6 minutes runtime.

If the PIN-code is activeted on the SIM-card the following init-string is needed: ATS0=2+CPIN=nnnn\r Unfortunately this string does not work on the PCD3.

Problem
The init-string with PIN-code "ATS0=2+CPIN=nnnn\r" does not work on the PCD3.

Reason
There is a problem in the firmware. It will be corrected in the next version >030.

Solution
Until a new version is available the GSM-modem will only work if the PIN-code is deactivated on the SIM-card. In urgent cases contact pcdsupport. A bugfix version will be available soon.

There is a problem when placing a communication module PCD3.F1xx and a memory module (PC3.Rxxx) on the same PCD3.

Problem
If a communication module is per example on slot 0 of the PCD3 and a memory module is per example on slot 1, it is possible that one of them will not work. If one of the modules is removed, the remaining one will work correctly.

Reason
There is a problem in the firmware. As soon as more than one intelligent module (e.g. PCD3.F1xx, PCD3.F2xx, PCD3.R5xx or PCD3.R6xx) are plugged on the PCD3.Mxxxx the detection of the module can fail.
This problem will be corrected in firmware version 031 (but is is existent also in version 030 / $31).

Solution
As long as firmware 031 is not released the two modules will not work properly together. A workaround could be to put the memory module PCD7.R550M04 directly on the communication module. Open the memory module PCD3.R550 and remove the card PCD7.R550. Open the communication module PCD3.F1xx and plug the card on this module.

With PG5 1.4.120 and PCD3.M5/M6 it is not possible to use the internal backup memory

Problem
With PG5 1.4.120 it is not possible to configure 256MByte memory size on the PCD3.M5 / M6 therfore no backup to the internal flash is possible.

Reason
It is not supported by the current firmware

Solution
The problem will be solved with the next official firmware 030. In urgent cases ask the support team for the inofficial version $28.

the minimum firmware version for PCD3.M5540 hardware version D is V023

As written in the manual the PCD3 User LED should work like the Error LED on the battery module. That means, if an error is present it should be lit and if no error is present it should be amber. The user is able to force the LED with a SYSWR instruction.

Problem

With firmware version 024 or lower the LED is working wrong. That means the LED is off when a error is present and the LED is on when no error is present. In the next official firmware it will be corrected.

It is possible to use a SYSWR instruction in the program or in the debugger to force the LED to a USER defined status:

SYSWR instructions:

With FW 024 or lower:
SYSWR  9000
                   K 1                 ; Force the LED to off

 SYSWR  9000
                   K 0                 ; Force the LED to on

With the next official FW:
SYSWR  9000
                   K 0                 ; Force the LED to off

 SYSWR  9000
                   K 1                 ; Force the LED to on

In some cases it is the same hardware, but due to the fact that the system contains a system ID written in EEPROM we can not guarantee that a xx7 PCD works properly with Classic firmware and invers.

Therefore it is not possible to download a Classic firmware to Classic PCDs and xx7 Firmware to xx7 PCDs.

General
A PCD CPU is bought as xx7 system or as Classic system. As described above, the possibility of a conversion is not guaranteed or offered by Saia-Burgess Controls AG.
There is no service "Convert from xx7 to Classic" or similar available at the repair service.

Additional details

• PCD2.M1xx, PCD1.M1xx
  The xx7 hardware is not identical to the classic PCD hardware, as result it can not be converted by a firmware change.
• PCD2.M5, PCD2.M480 and PCD3
  While it could be possible to run a Classic PCD as xx7 PCD (depending on the hardware type etc.), it is e.g. not possible to load a Classic PCD if it was bought as xx7 system (because in this case PG5 will not accept downloading the hardware configuration as the system ID is not correct).

For the correct handling of the new flash modules PCD3.Rxxx an and the PCD3.Fxxx communication modules an "I/O module check" has been implemented in the firmware. Unfortunately this check can cause problems on older hardware versions if more than two PCD3.Cxxx modules (extension cabinets) are used.

Symptom
The communication module PCD3.F121 as well as memory modules PCD3.Rxxx do not work when more then 2 extension cabinets PCD3.Cxxx are connected to a PCD3.
It is possible that the same PCD3 was working correctly but after an update of the PCD firmware this symptom appeared. In this case with the firmware update a new I/O module check has been introduced (please refer to the table below to find out in which versions this I/O module check is implemented).

Reason
An I/O module check has been introduced for the correct identification of the modules. In this way it is possible to avoid e.g. flickering outputs of an output module if a modem is (unintentionally) configured on this I/O slot. Also flash modules can be identified properly before accessing their content.

Unfortunately this check does not correctly recognize the modules plugged in to the PCD if the PCD is equipped with an old CPLD (Complex Programmable Logic Device) version as soon as more than two extension cabinets PCD3.Cxx0 are connected to the PCD.

Solution
Upgrading the CPLD version will solve the problems as the modules will correctly be recognized by the firmware. The upgrade of the CPLD corresponds to the hardware modification 8 on the PCD3 CPUs.

Hardware version D or above
The hardware version D has a correctly programmed CPLD and will therefore also detect intelligent I/O modules if more than 2 PCD3.Cxxx extensions are connected to the PCD3 CPU. No further action is to be taken.

Hardware version
These CPUs need to be updated to hardware modification 8 (CPLD update). Once this is done these PCD3s will support all PCD3.F1xx on slot 0 and also newer intelligent modules like per example the new flash moduls PCD3.Rxxx.
The update can be done with the "Firmware download Assistant in the following ways:

Yes, it is possible to use the S-Net MPI port on the PCD3.M5xxx as free RS 485 port (S-Bus or Mode C per example).

Requirements
- Firmware Version $12 or higher is needed.
- The port has to be assigned as port 3

The PCD3 ethernet communication stops after a few days/weeks. It doesn't respond to a ping anymore.

Problem
After a few weeks the Ethernet communitation on the PCD3 is not working anymore. No ping is possible. The rest of the program is working properly.

Reason
The problem is related to a firmware problem. A task is blocked. It happens normaly after 3 weeks. After a restart of the PCD the communication is running again.

Solution
A firmware update to version 020 is recommended when using IP-communication.

No the XOB 5 is only supported by the PCD4 and PCD6

Reason
The reason is, that the "IO Bus Quit fail" is a hardware interrupt created by the PCD4 and PCD6 I/O modules. On the PCD3 and also PCD2 I/O modules it is not supported and therfore not available.

Yes, it is implemented in the PCD3 with FW Version $12 or later. On the PCD2.M5xx0 it is supported with every firmware

The S-Net MPI-Port has to be configured as Port 3 instead of Port 10. It can be used as free standard RS 485-Port for S-Bus, to add a Bus-Terminal etc.

The wiring is:

D-Sub S-Net MPI                           S-Bus / Terminal ...
Pin
    3 RxD/TxD-P  --------------------- /TX /RX
    5 GND           --------------------- GND         
    8 RxD/TxD-N  --------------------- TX RX

After an Ethernet module has been replaced (and the IP address remained the same), it is often not possible connecting to the according PCD. The reason is that the PC "remembers" the old MAC address (which is different on every Ethernet module) and tries to connect to the old MAC address.

Symptom
After exchanging a PCD7.F65x or a PCD with Ethernet port, the communication between PC and PCD doesn't work any more. The same phenomenon can also be observed if the PCD is connected via a router (which also has a table where all IP addresses are listed together with its MAC address).

Reason
IP stations do address each other over its MAC address and not over its IP address. The first time a telegram is sent to a IP address, an ARP (address resolution protocol) telegram is sent which queries the MAC address for the relevant IP address. The destination station will then respond with its own MAC address (which will be stored by the originator of the telegram). After the MAC address has been received once, it will be stored on the originator for future use.
If the MAC address of a device changes, but the IP address remains the same, the originator of the communication (or a router or a switch in-between) needs to refresh its MAC table!  

Solution
To make the PC aware of the new MAC address, the PC needs to delete the MAC entry of the according IP address (for that it qureies it again for the next telegram). This is done automatically by the PC but takes some time.
To force a refresh of the MAC entry of an IP addres, the MAC adress of the concerned IP address in the local PC cache has to be deleted by using the arp command in the Windows Command Prompt. This can be done with the command "arp -d Entry_To_Delete":

The command prompt (screenshot above) can be launched from the Windws Start menu; Select "Execute" and type "cmd".

Short discription of  useful  ARP commands

• arp -a   display the  contents of the local cache
• arp -d   claer all contents of the correspond  IP- Adress
• ARP /?  display all possible parameter of ARP-Command
  

Remark
In case there are routers and switches in-between the PC and the PCD, also their cache needs to be deleted. This can be done by restarting the device.

No. Changing modules under tension can result in damage to the modules and CPU.

Remark
Please note that not only the PCD Power supply but also the tension on the I/Os themself (and the power supply of the I/O modules) must be removed before the modules can be removed without risk.

The problem may be related to a loose contact on the PCD3.K010 connectors used to connect the PCD3.M/Txxx CPU's and the PCD3.Cxxx expansion modules.

In this case, various error patterns may occur, such as

• - If an input is set to 1, then several inputs are set to 1 at the same time.
• - If an output is set to 1 in the application program, then the output is not set on the output module.
• - The status of the inputs is not correctly recognised in the application program.

The affected PCD3.K010 modules have a manufacturing date of 2028 (year 2020, week 28).

If the symptoms described above occur and a PCD3.K010 module with fabrication date 2028 is used, replace the PCD3.K010 module with a new PCD3.K010 module.

Order new PCD3.K010 modules and create an RMA request with the error description and the remark: CRABBMS-430 and select the option 'Advanced replacement'.

The date of manufacture can be seen on the white sticker on the PCD3.K010.

No, one master can only handle PCD3.T665/T666 or PCD3.T660 Rio's.

It's not possible to mix PCD3.T665/T666 and PCD3.T660 on the same master PCD.

The PCD3.T660 is no more available.

If existing PCD3.T660 Rio's networks need to be expand with new T660 Rio's then please do contact Saia-Burgess Controls AG:

When using a PCD3.A860 on a remote I/O station some points needs to be considered.

PCD3.T760
With the Profibus RIO PCD3.T760 the Blinds/Lightning module can be used. In the Fupla program the FBox with the ending “_RIO” is to be used. These FBoxes configure the module and control the in/outputs when communicating over Profibus. 


PCD3.T660
Is not to be used with a PCD3.A860. The Ethernet RIO PCD3.T660 is, because of his I/O mapping not able to control Blinds/Lightning module. 


PCD3.T665/T666
With a SmartRIO PCD3.T665/T666 the program for the module PCD3.A860 can be written directly on the remote I/O station. Therefore the FBoxes PCD3.A860 without the ending “_RIO” are to be used. If the system communicates via Ethernet these RIOs are to be used.

Overview

Since summer 2010 the PCD3 family (PCD3.M2xxx, PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx) do support the "full-duplex mode" and Auto-MDIX on the Ethernet port.

The PCD systems PCD1.M2, PCD2.M5 and the PCD3.T665/665 as well as the MB Panels PCD7.D4xx do support the "full-duplex mode" and Auto-MDIX since the first hardware version.

PCD3
The easiest way to detect wheter a PCD3 features the full duplex mode as well as Auto-MDIX is checking whether the RJ45 plug is equipped with LEDs. If it is, the PCD supports the full duplex mode as well as the Auto-MDIX feature (auto-crossing the signals).
In detail the following hardware version or later are required in order to support full duplex and Auto-MDIX:

• The PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx since hardware F.
• The PCD3.M2x30A4T1 and PCD3.M2x30A4T3 since hardware B.
• The PCD3.M2x30A4T5 since hardware C.

Before these hardware versions the PHY which was mounted on the PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx CPUs was configured by hardware to work in half-duplex mode and not to support Auto-MDIX. As result, the half duplex mode was used even if the partner device was configured in auto negation mode and the port should be initialized in full duplex mode.
This was the case on all PCD3.M3xxx and PCD3.M5xxx up to hardware version E 4.

Remark

• With "half-duplex": The data throughput is not devided by two because of this configuration as the limiting factor is not the the full/half duplex mode of the ethernet interface but rather the time it takes for the PCD to treat the received telegrams. The data throughput of the whole network is not affected either, since the next switch/hub will have an own port configuration for every port used (so on one port half-duplex can be used, and on another port full duplex can be used at the same time).
• If the Auto-MDIX is supported it is not necessary to use a crossover cable for directly connecting e.g. a PC to a PCD, or a MB Panel to a PCD.

Also it is possible connecting the Web Server of a PCD3.T760 using WebConnect 2.x, it is not automatically possible downloading a new I/O configuration.

Symptom
After having connected to the WebServer of a PCD3.T760 RIO, it is possible identifying e.g. the firmware version. But it is not possible to download a new I/O configuration (e.g. for monitoring/writing the I/Os without a Profibus DP or Profi-S-I/O master). After clicking the button "Download", the button "Start Monitoring" remains inactive.


Reason
The reason for this behaviour is that WebConnect 2.x does cash the content of the page by default. The refreshing method in the Web connect settings, section "setting webconnect" is set default to "Cache fill once".

Solution

• If it is possible, just update the SBC.Net WebConnect to version 2.0.16.4 or newer (please contact your local SBC support for the latest version). Starting with this version, the pages are never cached, if the connection type is "RIO". 
• In case SBC.Net WebConnect older than version 2.0.16.4 is used, change the WebConnect Caching strategy from "Fill Once" to "Don't cache pages from the PCD".

When using the modules PCD3.W800 and A810 on T760, it is necessary to know the address mapping which may be different that when they are used on a PCD3.Mxxx processor or on a LIO module (PCD3.Cxxx)!

In PG5 when the SIO or DP file is build, network variables are created in a new tag of the symbols editor. Those network variables (flags and registers) are at disposal in the different editors.

Attached the example done with PG5 1.4 110 contains a SIO file and a Fupla file!

PCD3.A810 on RIO module PCD3.T76

PCD3.W800 on RIO module PCD3.T760

Yes they are and starting in PG5 1.4 these modules are included in the S-Net Configurator by default. When using PG5 1.3 an import of a recent version of the GSE (or GSD) file is necessary. The firmware of the PCD3.T760 must be V 1.019 or later.

Problem
In the S-Net Configurator of PG5 1.3 (DP or S-I/O) the modules PCD3.W800, PCD3.A810 and PCD3.A860 are not implemented.
 
Reason
The mentioned modules are not implemented because at the time PG5 1.3 has been released the modules have not been available.

Solution
Upgrade the firmware of the PCD3.T760 to V 1.019 or later and with right-mouse-click on the T760 device in the SIO-configurator 'Remove Device ...' , delete the actual GSE-file. Then, import the new GSE file into the S-Net Configurator. Note that the new GSE file has to be named exactly 'PCD3.T760'. If the name is different, the S-I/O configurator will not use the new version. Old projects will also work correctly with the new GSE file.

Yes it’s possible to connect a PCD directly to the internet, but you have to protect your PCD against unauthorised access or cyber-attacks.

To protect the PCD against unauthorised access or cyber-attacks, it’s imperatively needed to take some protective measures.

Information about protective measures can be found on the support hp

If you need a PCD with cyber security levels SL3+ and based on ANSI ISA 62443 then checkout our PCD3.M6893 (QronoX PCD), this PCD was developed for cybersecure applications.

Information's can be found here.

Symptoms
Programmable PCD devices that act as S-BUS master on RS485 with PCD Firmware >= 1.28.20 and <= 1.28.33 get no answer from Slave devices on some of the S-Bus master requests, although S-BUS address, baud rate, polarity and line termination are ok.

Possible effects of the issue

Until now we have found that E-Line RIO communication seems to be more concerned of this problem than e.g. RS485 S-Bus data communication between CPU's.

In some of the cases the effect was, that it was not possible to write to the outputs of the E-Line RIO's or the change of values on the E-Line RIO Inputs was not transfered to the S-Bus master.

With the concerned Firmware it might be very difficult or impossible to download the user program over a gateway connection.

PCD Firmware 1.28.x for all programmable PCD types are concerned.

Reason

The reason of the issue is a error in the Firmware of the S-Bus master.
The problem on the Firmware is, that telegrams which contain DLE characters (B5 or C5) as last character of the telegram (CRC) where malformed because the last character is missing.

Since the CRC is calculated during runtime this malformed S-Bus request occurs depending of the content of the S-Bus request.

The (malformed) CRC is transfered with the S-Bus request from the master to the slave.

If now the slave receives the S-Bus request and the received CRC does not fit with the calculated CRC, then the S-Bus slave reject the S-Bus telegram.

Solution

In case you use the concerned Firmware on an installation with RS485 S-Bus Data communication, update the S-Bus master PCD to the newest available Firmware >= 1.28.34.

This Firmware do fix the issue CVE-2017-9628 related to Ethernet frame padding information leakage.
To avoid any problems in relation to this leakage we do recommend strongly to update to the latest Firmware
1.28.16 / 1.24.69 or newer as mentioned on the security upgrade section on this web-page.

Impact of the CVE-2017-9628
IEEE 802 specifies that packets have a minimum size of 56 bytes.
The Ethernet driver is expected to fill the data field with octets of zero for padding when packets are less than 56 bytes.
Resident memory and other data are used for padding in some implementations that could cause information leakage.
This attack is passive; the attacker can only see data that the affected devices sent out as part of a packet.

Vulnerability overview of the CVE-2017-9628
The previous implementation of firmware allowed other data from a known area of memory to be used in this field and could exfiltrate or leak data.

With Firmware >= 1.26.00, after Power off / on of the PCD, the LON bindings are lost.

Symptoms

The LON communication don’t works anymore after power off/on. In the commissioning tool, e.g. NL220  the Lon node is getting “red” after the function Network –>Test

Reason

In the FW 1.26.xx there is a problem with the file update on the Flash cards, the bindings are only updates in the memory but the operation to save them to the filesystem fails. Therefore the binding information is lost after power off / on.

Solution

The correction is done with >= 1.26.24. The firmware of the PCD and the LonIP FW have to be updated.

In the commissioning tool e.g. NL220 a Network -> Repair function has to be executed on the node.

Only the FW >= 1.26.00 are concerned. (e.g. FW 1.24.xx is not concerned of this problem)

The firmware 1.26.xx or later can be used only on the following PCD's with 8 MB onboard firmware memory:
PCD1.M0xx0/M2xx0, PCD2.M4x60, PCD3.Mxx60, PCD3.M6880 and PCD3.T665/T666/T668

The table below does show the hardware dependencies in relation with the COSinus firmware versions

Do use at least the PG5 firmware downloader version 2.1.311 or newer (included in PG5 patch 2.1.311 or newer) to prevent the loading of the FW 1.24.xx or 1.26.xx to a not compatible PCD.

It’s possible that after a FW update of the PCD to the FW 1.20.xx, 1.22.xx or 1.24.xx there is a entry in the FW history ‘FWDnld UnknownFW’ after the history line ‘FWDnld 1.2x.xx PLC CLASSIC’ as shown on the image below.

The history message ‘FWDnld UnknownFW’ was caused by an error in the old FW of the PCD and does have no signification.

Just ignore this message and clear the history messages.

This error is in fact a kernel error produced when different systems of the PCD are called simultaneously and get pointed on a invalid address. As the result the PCD goes in halt unless the software watchdog has been programme!                 

According to our experience the error happens very very rarely and most probably won't happen again!

In case an FBox library (or an IL program) uses a functionality which is not implemented in the PCD firmware, the PCD will not go in run but display the error message "SF not loaded" (e.g. in the PCD history or in the Online Configurator).

Symptom
After the download of a program a SBC-NT based PCD (e.g. PCD3) does not go in run but remains in halt. When going online with the Online Configurator a message "SF not loaded" is displayed.


Reason
The user program uses a functionality which is not implemented in the firmware (and therefore the PCD can not run the user program).

Solution
The solution is either updating the firmware, or avoiding the CSF which leads to the problem.
In case it is not know which CSF is responsible for the "SF not loaded", the SF library can be found based on the program line indicated by the Online Configurator (the program line is indicated with "Halt at xxx" in the Status; in the screenshot above the CSF is on program line 4). By using the Online Debugger, this CSF can be displayed by typing "DP4C10"):

   Display Program 4 Count 10 (Enter)
  

In this case, the CSF calls the SF library 26 (which is not implemented in the Firmware 1.10.51 which is used above).

How to know the functionality based on the library number?
Below you can find a list of the most commonly used System Function libraries (and in which FBox libarary they are used):

• SF library 0: S.SF.IP (e.g. Open Data Mode)
  Used by several IP communication drivers such as EIB/Net and for reading or writing the IP address of the PCD.
• SF library 2: System library
  Used by FBoxes for reading the Serial number
• SF library 4: S-Net library
  E.g. Used by FBoxes for Profi-S-Bus and Ether-S-Bus
• SF library 6: S.SF.DBLib (e.g. CopyTextBytes), previously the "ApplicationLib" for CopyText
  E.g. used by the Modem FBox library, HDLog to File library.
• SF library 7: File System library
  E.g. used by the FBoxes for the File System or "HDLog to File"
• SF library 9: IP Services (EMail, PPP, DNS, SNMP etc.)
  E.g. used by the EMail library and the WAA (Wide Area Automation) FBox library
• SF library 10: S-Web Alarming library
  E.g. used by the S-Web Alarming FBoxes and the DDC Suite
• SF library 13: Modbus library
  E.g. used by Modbus and the P-Bus FBox library
• SF library 19: LON over IP library
  used by LON over IP functions
• SF library 22: SPI framing protocol for PCD2/3.F2xx(x)
  e.g. used by the M-Bus library 2.6.100 and later
• SF library 23: Energy Manager library
• SF library 25: LON FT library
• SF library 27: ELine library for ELine modules
  Since PCD firmware version 1.24.xx

The single function codes (second line of the CSF call, "0" in the screenshot above) of the relevant libraries can be found in the definition files in folder
   c:\Documents and Settings\All Users\Saia-Burgess\PG5_20\Libs\SF\*.lib
(e.g. SFModbusLib_en.lib for the functions of the Modbus library.

As the "original" Instruction List Set (with the mnemonics STH, OUT etc.) could not be extended by an unlimited amount of new instructions, the call of new features such as the Open Data Mode, Sending of EMails etc. is realised with so called SFs (which stands fro "System Function"). These SFs are called using CSF instructions (Call System Function).

What is a SF library?
A System Function library is a a set of functions which are implemented in the firmware and which can be called with the IL mnemonic CSF. Usually one SF library contains several functions which are related to each other. A CSF expects the SF library and the function from this library, together with a set of parameters (described in the online help of the SF library which can be found in the IL Editor SEdit from PG5 2.0).

How is a CSF used?
In the user program a SF function is called using the mnemonic CSF, followed by the library, the function and the parameters:
CSF     [cc]     Library
                    Function
                    Parameter 1
                    Parameter 2
                    ...


This can be done from inside an FBox, or directly from an IL program (as the engineering is faster using the FBoxes, the most CSFs are called from FBox libraries).
The "translation" between meaningful names (e.g. S.SF.DBLIB.CopyTextBytes) and the code which is used by the firmware is done by PG5. For a list of the most commonly used SF libraries, please refer to FAQ 101568.

In July 2010 the firmware 1.14.23 has been introduced into production for the PCD2.M5xx0 and the PCD3.Mxxx0. This FAQ lists the main differences between versions 1.10.51 and 1.14.23.

New features
please note that in order to take advantage of these new features PG5 2.0 SP1 (PG5 2.0.150) is required.

• Increased amount of available flags (14335 instead of 8191), see FAQ 101447
• S-Web and FTP Server as well as the IP Enhancements (DHCP, DNS, SNTP and PPP) can be configured in the Device Configurator, see FAQ 101464
• Webserver access levels can now be configured in the Device Configurator (was before in the WebBuilder settings), see FAQ 101613
• IEEE floating point values can be displayed on the S-Web server (display format is “e”), see FAQ 101188
• Number of COBs increased to 32, see FAQ 101467

Main corrections

• SYSWR for DB backup failed after a lot of backups, see FAQ 101466
• STXT with more than 512 bytes sent a wrong text, see FAQ 101468
• The IP address for the Open Data Mode System Function “ConnectTCP” could not be given as constant 

Hardware compatibility of firmware 1.14.23 with PCD3 systems
The firmware 1.14.23 requires a PCD equipped with 4 MB onboard flash. Therefore the minimal hardware versions for installing the 1.14.23 and later are:

For PCD3 systems older than listed the firmware 1.10.61 is the last firmware which can be installed on these systems. This firmware is and remains available on the support site in parallel to the 1.14.23.

Remarks 

• When updating from 1.10.xx
  Please note that the user program as well as the communication settings are lost during the firmware update from 1.10.xx to 1.14.xx (or 1.16.xx) 
• BACnet applications
  The BACnet firmware 1.14.26 is compatible to this new production firmware. Please download the latest BACnet firmware package for PCD firmware 1.14.xx from the support page (link below).

In case a text with more than 512 bytes is sent with a firmware older than 1.14.23 the according text has not been sent correctly.

Symptom
When sending a text with a length of more than 512 bytes on a PCD3 or a PCD2.M5 with a firmware older than 1.14.23 the text which is sent is not correct.
In case the text to be sent contains sub-texts which are introduced using interpreted text (e.g. the $Lnnnn) and the final length to be sent is more than 512 bytes, the same phenomenon can be observed.

Solution
Please update the firmware of your PCD to version 1.14.23 or later.

Up to firmware version 1.14.23 the maximal amount of COBs (Cyclic Organization Blocks) has been 16. In firmware 1.14.23 the amoung of COBs has been increased to 32. Thus on PCD2.M5 and PCD3 and newer systems up to 32 COBs can be used (COB to 31).

Remark
Please note that PG5 2.0 Service Pack 1 (PG5 2.0.150) is required in order to program the COBs 16 and higher.

In some cases, usually after a lot of backups which have been executed, the error bit 7 (flash task already started) or 8 (flash error) is set with firmware older than 1.14.23.

Symptom
A backup DB to flash (IL instruction "copy TEXT/DB to flash card", SYSWR 3000 or 3100) fails and the error bits 7 and/or 8 are set. This error remains, even after waiting several minutes without re-attempting a backup to flash.

Solution
This problem is corrected in firmware 1.14.23 or later. Please update your PCD firmware in order to solve this problem.

In May 2010 the firmware 1.10.51 has been introduced into production for the PCD2.M5xx0 and the PCD3.Mxxx0. This FAQ lists the main differences between these versions.

New features

• The Serial-S-Bus mode “Parity master” is now supported on all serial ports of the PCD, see FAQ 101103

Main corrections

• Increased stability for BACnet upload/merge (requires BACnet firmware version 1.10.50), see FAQ 101417
• Correction which avoids potential data loss on the SD cards when a card with more than 256 kBytes capacity is filled by 70%, see FAQ 101377
  In case an SD card is used on the PCD, the update of the firmware to the version 1.10.51 is strongly recommended!
• Avoided inter-character delay on port 2 and 3 (PCD2.M5) or 0 and 3 (PCD3) which could lead to communication problems, see FAQ 101382
• A Bus Error could occur in some specific cases, see FAQ 101418
• Reading Ni1000 sensors with a PCD2/3.W340 by the media mapping returned wrong values, see FAQ 101416
• Profi-S-I/O and Profibus DP Master did not work, see FAQ 101244

For writing data to files on the PCD file system and for sending SMS or EMails it is possible to enter the content of medias (registers, flags etc.) into the text to be written or sent. This is done by placing e.g. a $R0100 into the text to be sent. At the time of writing, the "$R0100" will be replaced by the content of the register 100.

While in the beginning only points could be used as seperators in interpreted texts, it is also possible using the comma as separator with recent firmware versions. In this case, instead of a point a comma is to be used:


Firmware dependencies
The comma separator can be used starting with the following firmware versions:

Under certain circumstances (if the file system is occupied by more than 70%) data losses on SD cards bigger than 256 MBytes have been observed.

Symptom
Under certain circumstances data losses on SD cards bigger than 256 MBytes have been observed. By analyzing these reports we have seen that in case more than 70% of the available memory on such a card is used it is possible that data is lost on the next power-up of the PCD or after the card has been re-inserted into the memory module holder (R600 / R6000) or opened by the SD Flash Explorer.
In case of many delete operations executed by the module the mentioned data loss can also occur if less than 70% of the available memory is used (due to the ware-out management of the SD card which varies the used memory areas).

Solution
An additional safety mechanism in the PCD firmware 1.10.51 as well as in the SD Flash Explorer in order to avoid future potential data loss on concerned cards has been implemented.
As soon as the system is rebooted (or the SD card is re-inserted into the R600 / R6000 mounted on a PCD with a new firmware versions) actions are taken in order to avoid the mentioned potential data loss.

The according firmware 1.10.51 (for PCD2.M5xx0 and for PCD3.Mxxx0 systems) with the new safety mechanism can be found on the support site www.sbc-support.ch.

In addition to the safety mechanism a new SD Flash Explorer version 2.0.215.0 features a “Backup” and a “Restore” feature which allows the creation of a backup of the file system.
This SD Flash Explorer can be downloaded from the support site from the section for the PCD7.R-SDxxx and will be distribued with the SP1 for PG5 2.0.

Remarks

• Even if the file system on a SD card is already filled up by more than 70%, it is still possible to download the data over FTP as long as the PCD is NOT switched off. This method is recommended before updating the firmware in order to guarantee that no data is lost.
• SD cards delivered by Saia-Burgess Controls AG after week7 of 2010 contain a mechanism that avoids the above mentioned data loss (as long as the card is not formatted with a firmware older than 1.10.51).
  

Since summer 2010 the PCD3 family (PCD3.M2xxx, PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx) do support the "full-duplex mode" and Auto-MDIX on the Ethernet port.

The PCD systems PCD1.M2, PCD2.M5 and the PCD3.T665/665 as well as the MB Panels PCD7.D4xx do support the "full-duplex mode" and Auto-MDIX since the first hardware version.

PCD3
The easiest way to detect wheter a PCD3 features the full duplex mode as well as Auto-MDIX is checking whether the RJ45 plug is equipped with LEDs. If it is, the PCD supports the full duplex mode as well as the Auto-MDIX feature (auto-crossing the signals).
In detail the following hardware version or later are required in order to support full duplex and Auto-MDIX:

• The PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx since hardware F.
• The PCD3.M2x30A4T1 and PCD3.M2x30A4T3 since hardware B.
• The PCD3.M2x30A4T5 since hardware C.

Before these hardware versions the PHY which was mounted on the PCD3.M3xxx, PCD3.M5xxx and PCD3.M6xxx CPUs was configured by hardware to work in half-duplex mode and not to support Auto-MDIX. As result, the half duplex mode was used even if the partner device was configured in auto negation mode and the port should be initialized in full duplex mode.
This was the case on all PCD3.M3xxx and PCD3.M5xxx up to hardware version E 4.

Remark

• With "half-duplex": The data throughput is not devided by two because of this configuration as the limiting factor is not the the full/half duplex mode of the ethernet interface but rather the time it takes for the PCD to treat the received telegrams. The data throughput of the whole network is not affected either, since the next switch/hub will have an own port configuration for every port used (so on one port half-duplex can be used, and on another port full duplex can be used at the same time).
• If the Auto-MDIX is supported it is not necessary to use a crossover cable for directly connecting e.g. a PC to a PCD, or a MB Panel to a PCD.

This FAQ contains an overview over the firmware versions currently used in production (which means that this firmware version is installed in our production facility).

Firmware versions used in production
The following firmware versions are currently used in production. For more information regarding the relevant firmware, please refer to the version information document of the according page.

PCD firmware versions

MB Panel firmware versions

RIO firmware versions

When working with PCD systems you will cross the expression "Saia PCD® COSinus" sooner or later. This FAQ explains what "Saia PCD® COSinus system" stands for.

The expression "Saia PCD® COSinus"
In general the expression "Saia PCD® COSinus" stands for PCD systems which are equipped with Freescale (previously Motorola) Coldfire CPU technology. The "non-Saia PCD® COSinus" systems from Saia-Burgess Controls AG are based on Freescale 68k CPU technology (e.g. PCS1, PCD2.M170 etc.).
The Coldfire CPU technology is a new and more performant CPU generation, new development is generally realized on Coldfire CPU (while the 68k CPUs still are available in parallel).
The first PCD system based on the Saia PCD® COSinus technology has been the PCD2.M48x. For this system the whole firmware has been re-written. The firmware of new systems is built up based on the firmware developed for the PCD2.M48x platform (having the same core modules). New firmware functionalities (e.g. Modbus which is implemented in the firmware) are basically designed for the Coldfire CPU technology and thus for Saia PCD® COSinus systems.

Saia PCD® COSinus based systems
The following list contains the main PCD systems which are based on Saia PCD® COSinus technology.

• PCD3.Mxxx
• PCD2.M48x
• PCD2.M5xxx
• PCD7.D4xx
• PCD1.M2xx (currently under development)

Does this mean that all Saia PCD® COSinus systems support the same firmware features?
No! Although the same base modules of the firmware are used, it is depending on the PCD system whether a specific feature is supported or not. For example the http protocol is supported by PCD3 and PCD2.M5xxx systems, but not on PCD2.M48x.

With an activated software watchdog the processor monitors itself and restarts the PCD in the event of a malfunction or a loop.

Description (extract from the hardware manual)
The hardware watchdog provides maximum security. However, for non-critical applications, a software watchdog may be suffcient, whereby the processor monitors itself and the CPU is restarted in the event of a malfunction or a loop.
The core of the software watchdog is the instruction SYSWR K 1000. When this is first issued, the software watchdog function is activated. This instruction must then be issued at least every 200 ms, or the watchdog will trigger and restart the controller.

Usage

• Placing a "Watchdog"-FBox in a FUPLA-file is the easiest solution:
  
• Instead of using the FBox it is possible calling the Software Watchdog in IL (using the instruction SYSWR K 1000)
  

If there is a SIO-Master and a DP-Master configured the SIO-Master does not go in the "Operate" state to make the data exchange.

Symptom
It can happen with the firmware version 1.10.16 that a PCD3 or a PCD2.M5 does not work as SIO-Master if they are also DP-Master.

Solution
This behavior is solved with the version 1.10.51 or newer (the first version which corrected this situation was 1.10.20). Please update the firmware of your PCD in order to solve this issue.

The WebServer2 is a re-implementation of the previous WebServer on Saia PCD® COSinus systems and of course compatibel to the previous version.

History
The first implementation of a Web Server on PCD systems has been realized around the year 2000. With growing experience additional features and higher performance have been requested. In order to fullfil this requirement, the WebServer has been re-implemented (with the result of the WebServer2).

What is new in the WebServer2?
In general the WebServer2 is functionally compatible to the previous implementation. In addition the following new features are supported:

• HTTP 1.1 support
• HTTP caching is supported. As result the in FAQ 100708 is no longer to be applied; It is recommended to enable the caching for the JVM (option "keep temprary files on PC") when working with the WebServer2.
  
  Remark: If the caching is not enabled, you will not profit from the supported caching; it will then work as it has before with the previous WebServer. 
• Better performance
• Parallel acces to files is properly supported (acces is no longer interrupted if another client loads the IMaster applet)
• Multiple Web clients can access the Web Server on the same physical interface with (Ether-S-Bus or Profi-S-Bus)
• Easier understandable error messages
• When texts are entered, the length of the text is specified (and no longer filled up with space characters)
• The WebServer2 does provide more information on the default page and has a nicer look. By viewing this page it is easy figuring out whether the WebServer2 is running on a PCD

Firmware (FW) supporting the WebServer2
The table below indicates the first firmware versions supporting the WebServer2. Systems not listed in this table do not feature the WebServer2.

^*) Please note that in the first pilot firmware not all features have been supported.

Remark
The only incompatibe difference between the previous WebServer and the WebServer2 concerns users that use the "HTML forms":

• The previous Web Server used:
  %%TAG%
• The WebServer2 expects (the "value" is no longer automatically added by the Web Server):

Yes, a new set of instructions for calculation with IEEE floating point values (single and double) has been added to the firmware of PCD2.M480, PCD2.M5xx0 and PCD3.

Introduction
Motorola FFP (Fast Floating Point) has been used for floating point calculations since the beginning of PCD history. In order to simplify the interface against systems which do not support FFp but IEEE format for floating point values the instruction set of the PCD has been extended. All "twin" of all instructions available for the calculation with FFP values are now also available for IEEE calculations.

What are the instructions in detail?
Each of the existing instructions for FFP (the default) do also exist for IEEE Float and IEEE Double data. 

• For IEEE Float, precede the mnemonic with an 'E' character, for example EIFP, EFADD (instead of IFP or FADD) etc.
• For IEEE Double, precede the mnemonic with 'D', for example: DIFP, DFSUB.

Minimum Firmware (FW) requirement for this feature

PCD systems not listed in this table do not support this function.

Remarks

• These instructions can only be used with PG5 2.0.
• There is also a new instruction for the conversion from IEEE single to IEEE double (and vice versa):
  EFPD (single to double) and DFPE (double to single). These instructions are supported by firmware version 1.10.15 and later.
• The instructions for convertig a IEEE double value to an integer value and vice versa (DFPI and DIFP) are working correctly starting with firmware 1.14.23.
• IEEE single values can be displayed by the S-Web Server using the format "e" (e.g. 172.16.1.127/cgi-bin/readVal.exe,e) 

For "reading" a value from a PCD text (e.g. copying "1234" from a PCD text with content "The next number is: 1234" into a Register) a new System Function has been added for PCD3 and PCD2.M5xx0.

What does this System Function (SF) do?
The new function "S.SF.DBLIB.ReadANumberFromText" allows reading a number from a text and copy it into a register. Starting from a provided pointer, the next number will be searched and copied.

Where do I find the documentation for this function?
This function is documented in PG5 2.0. The easiest way to open the documentation is opening the SEdit, selecting the "SF DB Access Library" and hitting "F1":


Minimum Firmware (FW) requirement for this feature

PCD systems not listed in this table do not support this function.

Remark
This feature can only be used with PG5 2.0.

For parsing a PCD text for a specific expression (e.g. finding "world" in a PCD text with content "Hello world") a new System Function has been added for PCD3 and PCD2.M5xx0.

What does this System Function (SF) do?
The new function "S.SF.DbLib.SearchText" allows searching a text for a specific expression. If this expression is found, the SF returns the position of the expression within the text.

Where do I find the documentation for this function?
This function is documented in PG5 2.0. The easiest way to open the documentation is opening the SEdit, selecting the "SF DB Access Library" and hitting "F1":


Minimum Firmware (FW) requirement for this feature

PCD systems not listed in this table do not support this function.

Remark
This feature can only be used with PG5 2.0.

The XOB 8 who is called when the firmware detects an invalid instruction (Invalid OPC) in the user program is no longer called on the systems Saia PCD® COSinus (PCD3, PCD2.M5, PCD2.M480).

On the new systems, the control of the Invalid OPC is executed at the startup during the precompilation. So the XOB 8 will never be called.
This new mechanism is implemented to increase the speed and the flexibility of the systems Saia PCD® COSinus.

If the communication on both ports of a PCD3.F281 does not work then it's possible that the PCD3 does contain a FW which not does recognise the PCD3.F281 module.

Symptom
The communication on both ports of the PCD3.F281 does not work at all. The firmware installed is 1.08.23.

Reason
The firmware does not recognize the Belimo MP Bus module.

Solution
To solve the problem please install PCD3 firmware version 1.10.16 (the first firmware solving the problem was  version 1.08.51).

In very special situations a PCD can get overloaded because of external influences in a way that a "KERNEL ERROR" or a "SWTO ERROR" (System Watchdog Timeout Error) is causing the PCD to restart automatically.

Symptom
In some very special circumstances (if a PCD is stressed by extreme external influences) the PCD3 automatically executes a reboot and then goes in HALT (if the software watchdog is programmed, the PCD automatically goes in RUN after the restart).
When going online and reading the PCD history, an entry "KERNEL ERROR" (on firmware versions 1.08.xx and earlier) or "SWTO ERROR" (on firmware versions 1.10.xx and later) can be found.

Reason
For saftey reasons the PCD executes a reboot in case the System Watchdog is no longer called within a specific time (this is the same behavior as the Software Watchdog, but directly on firmware level). In case of the Kernel Error a task-overload has been detected (FW indicating a Kernel Error (1.08.xx and earlier) do not feature the System Watchdog). 
Such a situation could e.g. be caused by an Ethernet telegram bombardement of several thousend telegrams per second or if a connected FDL network is disturbed heavily over a long time. In such a situation the PCD (with FW older than 1.10.xx) does only treat the interrupts generated by e.g. the IP telegrams and no longer executes the rest of its tasks (for security reasons, this state is interrupted by the automated reboot of the system).
 
Solution
A new Kernel together with other improvements which can avoid situations leading to SWTO Errors have been implemented in firmware version 1.10.xx (or in the special firmware with new kernel 1.08.19.12). Thanks to these improvements the PCD is even more robust against the mentioned influences which can cause a "SWTO Error" (or a "KERNEL ERROR").

Important

• Please note that in case a Software Watchdog is programmed, the PCD does automatically go in RUN after the restart executed by the System Watchdog (if no Software Watchdog is programmed, the PCD goes in HALT after the reboot caused by the System Watchdog)
• In general it is recommended using firmware version 1.10.16 or later rather than 1.08.19.12.

The PCD3 systems equipped with an Ethernet port and the PCD2.M5540 are able to send emails. But sending e-Mails is not only depending on the CPU itself.

The PCD3 systems equipped with an Ethernet port and the PCD2.M554x support SMTP (Simple Mail Transfer Protocol). Sending emails does not only depend on this feature but as well on the ISP (Internet Service Provider), the firewalls and router configurations between PCD and ISP.

The attached checklist with the criterias to verify with your provider and / or your IT support shall help to check whether sending E-Mail is possible.

This error message appears if the used firmware on the CPU does not support the "active and non ACK" filter for the S-Web alarming functionality (e.g. a PCD2.M150 with firmware 0D3).

Symptom
Instead of the alarm list of the S-Web alarming macro, the message "Failed to get data on alarm.exe" is displayed on the alarming page.

Reason
The reason is that the macro tries receiving the alarms filtered by the "active and not acknowledged" state of the alarms. This does only work if this feature is implemented in the according firmware.

Solution
Please update the firmware (FW) of your PCD system to the firmware supporting the according feature (see table below).

^*) On PCD3 and PCD2.M480 systems the "active and not acknowledged" filter has already been implemented in previous versions, but has been improved this indicated version.

Yes, this is possible by calling the system function (CSF) "IPGetLocalConfig".

Introduction
For having the possibility to read the current IP configuration from the user program, a specific System Function has been added to the firmware. This function does return the IP address, the subnet mask as well as the default gateway (each address in one register). The returned value contains the full IP address in one register (each byte or the register contains one octed of the IP address):

Example
This System Function is part of the IPD Library. In order to use these functions, the file "IPLib.inc" is to be included to the source file where the function is called. This can be done with the line:

$INCLUDE "IPLib.inc"

The IP configuration can then be read in th following way:

Returned IP address (hex):               0xAC100179h
IP address in "Dot-decimal notation": 172.16.1.121 (0xACh = 172, 0x10h = 16, 0x01h = 1, 0x79h = 121)

Firmware versions supporting the GetLocalIPConfig
Please refer to the table below for the first firmware versions that support the "IPGetLocalConfig" function.

Remark
The include file "IPLib.inc" from PG5 1.4.300 and earlyer versions needs to be updated in order to "know" this feature. Therefore please download the file "IPLib.inc" attached to this FAQ and replace the existing file from PG5 which is located in the "Libs/App" of PG5:

c:\Program Files\SAIA-Burgess\PG5 1_4\Libs\App\IPLib.inc

In firmware version 1.08.xx for systems running the Saia PCD® COSinus firmware, the system watchdog has been introduced. If a PCD reboots because of the system watchdog, the message "SWTO ERROR" is entered in the PCD history.

What for is a system watchog?
The system watchdog is a security measure which avoids a situation where the system (PCD) is blocked and does not properly execute the program any more. If the OS (Operating System) is "locked" in a loop and does no longer properly execute its tasks (among others, the user program), the PCD is automatically re-started. 

What does the system watchdog do?
The (internal) system watchog is configured directly on the CPU and will cause a re-boot if it is not triggered in a cyclic manner. Every reboot caused by the system watchdog is entered in the PCD history with the message SWTO ERROR (SWTO stands for System Watchdog TimeOut).
The behaviour after the automatic reboot caused by the system watchdog is depending on the software watchdog which can be programmed in the user program:

• If the software watchdog in the user program is enabled, the PCD will automatically go in RUN after a reboot caused by the system watchdog. 
• If no software watchdog is programmed in the user program, the PCD will go to "Halt" after it has rebooted because of the system watchdog.

Does the system watchdog conflict with other watchdogs?
No, the system watchdog does not conflict with e.g. the software watchdog programmed in the user program or with a hardware watchdog.  
 
When has the system watchdog been implemented?
The system watchdog has been implemented in firmware version 1.08.xx. The first production versions for the relevant systems can be found in the table below:

Remark
Note that the system watchog does not detect a bogus user program (e.g. an infinite loop) and therefore the usage of the software watchdog in the user program is still recommended.

The information provided in the history or the "Diagnostic file" of the PCD does not always give enough information for the firmware developpers to find the reason for e.g. a crash of a PCD. If more information is required in order to trace back a crash, a dump of the whole memory (SRAM, DRAM and FLASH) of a PCD can be done. This FAQ does apply to PCD1.M2, PCD2.M480, PCD2.M5xxx, PCD2.M45x0, PCD3 (including PCD3.Mxx60) and PCD7.D4xxxT5F (Programable MB-panels).

Working principle
For dumping the memory of one of the following systems a dedicated small executable SaiaDump.exe is available as standalone tool.

• PCD1.M2
• PCD2.M480
• PCD2.M5
• PCD2.M45x0
• PCD3
• PCD3.Mxx60 (fast CPU)
• PCD7.D4xxxT5F (programmable MB-panels)

Usage of the stand alone tool SaiaDump.exe:
This tool is called by a batch file which will call an executable (SaiaDump.exe) with hardware specific parameters. The executable will establish an USB connection to the PCD and will read out the memory content. This content will be stored in 4 files and all these files will automatically be stored in a *.zip archive.

General remark:
In order to obtain all necessary information it is important that the dump is made while the CPU's memory still contains the last information.
Since this information is lost (overwritten) when the PCD re-boots, it must be achieved that the PCD does not reboot in case of a crash (e.g. Bus Error or Kernel Error).
Therefore a specific SYSWR has been implemented.
This command is to be executed on the PCD e.g. in XOB 16 before a crash occurs (on every boot, because it is reset on each power off).

Software installation of SaiaDump.exe tool

• Download the archive "SaiaDump_V1_3_006_Rev211101.zip" from this FAQ
• Unpack the *.zip archive on your PC or Laptop
• In the extracted folder "SaiaDump" you'll find several batch files (e.g. RUN_DUMP.bat or RUN_DUMP_PCD1M2xx0.bat).
  By double-clicking on the file RUN_DUMP.bat, a dump is started (make sure that PCD is connected with a USB cable and no PG5 is running)
  
  After a successful dump a new *.zip archive with the name "PCDDump_date" will be stored in the same directory.
  Please send this archive (it should contain four files with the extension *.blk or *.bin and a log file) to the support. 

Preparing the PCD
In order to cause the PCD not to reboot in case of a crash, add the following lines to the code of your CPU (and remove the watchdogs, if present).
Alternatively, you can also add and link the file "DontRestartAfterCrash.src" which is contained in the folder "PCD_Preparation" off the "SaiaDump_exe.zip" to the concerned CPU in your PG5 project.

$INIT                   ; Add the following lines to the XOB 16
SYSWR K 9999     ; Instruction to cause the PCD not to
K 1                       ; reboot after a crash
$ENDINIT

This instruction has been implemented first in PCD3 firmware version 03A.
Therefore please also make sure that FW version 03A or higher is installed on the system.
The SBC Dump tool can only dump the memory of a PCD that has boot loader version 035 (created in April 2006) or higher installed.
In case your PCD has a too old boot loader or if you are in doubt of the boot loader version of your PCD, please refer to FAQ 100680 in order to learn more about how to find out the boot loader version and how to update the boot loader version. 

Dumping the PCD memory
After the next crash, the PCD will not re-boot anymore and will blink with all tree LEDs simultaneously instead. Please note that the SYSWR K 9999 (see above) must have been introduced before the crash and the LEDs must blink in this state! In this (and only in this) situation it is possible dumping the memory of the PCD:

Use of the stand alone tool SaiaDump.exe:
Launch the SaiaDump.exe for retrieving valuable debug information (it is also possible dumping the PCD if the PCD is in boot loader state or run for test purposes, but no valuable debug information can be retrieved from these files).
For launching the SBC Dump is should be enough to double-click the file RUN_DUMP.bat.

Additional information for PCD3.Mxxx7
The same tool can also be used for dumping the memory of a PCD3.Mxxx7. But note that the usage of the SYSWR listed above is not to be used.

In firmware 03B and 03C an S-Bus broadcast telegram will block the communication interface until the next reboot of the PCD.

Symptom
When using firmware version 03B or 03C on either a PCD2.M480 or a PCD3.Mxxx0, the communication stops working after a sent broadcast. This only applies if the concerned PCD is acting as master on the S-Bus network.
This phenomenon occurs on S-Bus (Serial-S-Bus, Ether-S-Bus or Profi-S-Bus).

Reason
In firmware 03B and 03C an S-Bus broadcast telegram will block the communication interface until the next reboot of the PCD.

Solution
In order to resolve this problem, please update the firmware of your concerned PCD.

The first versions of the PCD3.M5340 controller have been delivered with a firmware that does not support the usage of the RS485 port on port 3.

Problem
The communication RS 485 on port 3 of the PCD3.M5340 is not working correctly. 

Reason
Due to a problem in the firmware, the port is not correctly initialized to RS 485.

Solution
Upgrade the PCD3 firmware to version 1.08.23 or higher.

Remark
There is no problem for the usage of the port 3 as RS422 port.

If a wrong or invalid firmware is downloaded to a PCD3, the firmware download progress bar reaches 100%. After the download finished, an error message appears indicating a failure caused by a NAK response.

Symptom
After the download of a firmware file the following error message from the Firmware Downloader (FWDnld) appears. The message is "Download failed on END command. Error: NAK response."
§ix100527§

Reason
The reason for this message is a "NAK" (Not Acknowledged) response from the PCD. Before the PCD loads a new firmware, it is verified by the PCD. If this verification fails (because of e.g. a wrong checksum of the firmware of because the firmware is not intended for this CPU type), a NAK response is sent by the PCD to the Firmware Downloader.

Solution

• Make sure the firmware you download is created for the CPU type you have attached (a firmware for e.g. the PCD2.M480 will not run on a PCD3.Mxxx0 system)

• Make sure the file you have downloaded is not corrupted (e.g. while the download from the internet or similar). In case of doubt, re-download it.

In order to simplify the interpretation of firmware versions and to avoid confusion regarding implemented features and bug fixes in different firmware versions, a new firmware version format for Saia PCD® COSinus based systems will be introduced.

Arguments for the new format
The new firmware version naming allows a clear and easy comparison between the different versions and their implemented features (PCD type specific) and bug fixes.
Questions like "Why is the Alarming functionality of the PCD3 Web Server implemented in firmware version $31 but not in version 031? - They both do have the same number..." should be past (however, if you're interested in the answer, please refer to FAQ100176)

Format description
The new firmware version name does consist of a major version, a branch version and a minor version separated by a dot (.).
Note that the prefix characters “0”, “$” or “#” are no longer used in this notation.

Concerned systems
The new firmware version format is applied to the systems based on Saia PCD® COSinus firmware (Classic and xx7). These are

• PCD1.M2xxx
• PCD2.M48x
• PCD2.M5xxx
• PCD3.Mxxxx
• PCD7.D4xx (MB Panels)

While the firmware names for the MB Panels and PCD1.M2xxx do have this format from beginning, it was introduced on the PCD3 and PCD2.M480 systems with the firmware version after 03B.

Version flow example
Below an example for a version flow. If e.g. a bug is corrected in the version 1.06.01, also version 1.07.02 and all following 1.06.xx versions do/will have this correction implemented.


Version types

• Released beta- or maintenance versions (equivalent to the current “Bxx” or “#xx” versions).
• Released Production versions (equivalent to the current “0xx” versions): These versions are introduced in the production.
• New function versions (equivalent to the current “$xx” versions).

Compatibility with PG5
The new firmware names are fully supported by PG5 V 1.4.200:

Previous versions of PG5 will only show the first three digits of the firmware version (e.g. “106” instead of “1.06.08”). The full firmware version can always be read by displaying byte F0F0 in the “Online Debugger” (type DYF0F0 ):

While the serial PGU port of systems before the PCD3 did always work as PGU port when connecting a PCD8.K111, the serial PGU port of the PCD3 can be configured for using a modem. If this is done, it is no longer possible attaching a PCD8.K111 and establishing a PGU connection.

Symptom
It is not possible going online with the PGU communication mode using a PCD8.K111 programming cable plugged in on the D-SUB labeled "Com/PGU" of a PCD3.M5xx0.

Reason
The port "Com/PGU" of the PCD3.M5xx0 can be used as either PGU port for programming the PCD or for connecting an external modem to the PCD3. In case a modem is connected, the full handshake must be enabled and by doing so the detection mechanism for a PGU connection established with a PCD8.K111 is disabled.
A second reason could be that the firmware 039 is installed on the PCD3. In this case a firmware problem avoids a successful serial PGU connection.

Solution
Connect to the PCD using a USB cable (which always works as programming connection) and upload the current hardware settings of your PCD3.
§ix100519§
After having uploaded the current configuration of the PCD3, check that the checkbox "Full RS232-handshaking on Port 0" is not checked. If it is checked, uncheck it and download the modified hardware configuration in order beeing able going online with a "serial PGU" connection.

If it is still not possible going online with the PCD3, please check the firmware version of the PCD3. Note that the version 039 has a known problem that avoids going online over the Serial PGU connection. In case you are concerned by this problem, please contact your local sales office and request a firmware that fixes this problem (e.g. 03A).

Due to a firmware problem the clock of a PCD3.Mxxxx equipped with a firmware x3x older than version 037 can be corrupted in run time.

Symptom
The clock value of a PCD3.Mxxxx equipped with a firmware x3x older than version 037 can run "accelerated" while the PCD is in run. After a power off / on of the PCD, the clock will be set correctly again.

Reason
This behaviour is caused by a problem in the firmware and is related to the "Soft RTC" which has been introduced in version 030.

Solution
This problem is corrected in firmware version 037. Please refer to the support site where you can find the latest version of the PCD3 firmware in the section "Product information --> PCD3 --> Mxxx0"

Depending of the PCD type and the used port it's possible to use the XON/XOFF protocol.

Symptom
A SASI (Assign Serial Interface) in mode MC2 (Character mode with Xon/Xoff protocol) fails. The error flag is set after the SASI instruction.

Reason
The XON/XOFF protocol is not supported on this PCD or port.

List of supported ports
PCD3.M5xxx: the mode MC2 is supported on port 0 (Com/PGU) and also on the PCD3M5340 in RS422 on port 3 (S-Net/MPI).
PCD2.M5xxx: the mode MC2 is supported on port 2.
PCD1.M2xxx: the mode MC2 is not supported.


Remark
Please note that on the PCD2/3.F2xx modules, the XON/XOFF mode is not yet supported (which is not correctly documented in the manual 26/789).

When downloading a recent PCD3 firmware (e.g. 031) over e.g. USB it can occur that the error message "Download failed on END command" is shown at the end of the download. The LEDs of the PCD remain blinking in the "Firmware download" sequence.

Symptom
At the end of the firmware download (in S-Bus USB mode) of e.g. version $33 the "PCD Firmware Downloader" an error message window pops up saying "Download failed on END command, Error: No response."
After a reboot the PCD boots properly and has loaded the new firmware version.
§ix100473§

Reason
The PCD does answer the "END command" telegram too slowly. This is because the PCD first needs to calculate the CRC of the firmware wich takes a bit longer than 250 ms (which is the default timeout on S-Bus PGU).

Solution
In order to avoid this error message please increase the timeout of the "S-Bus USB" to e.g. 500 ms:

• Go offline with your PCD3

• In the "Online Settings" of the relevant CPU click the button "Setup" behind the channel selection "S-Bus USB"

• Change the default value of 250 ms to 500 ms

• Accept with "Ok" and close the "Online Settings"

Note
The same symptom can also appear when using other communication channels, e.g. Ethernet. In case the same message apperas also on Ethernet, please also update the accoring settings.

In case a PCD3 has installed a firmware version older than version 020 the download of a recent firmware version (e.g. 031) fails. The error message of the "PCD Firmware Downloader" in this case is "NAK response".

Symptom
It is not possible downloading a firmware newer than $25 (e.g. 031) to a PCD3 having installed a firmware version older than 020 (e.g. 018). The progress bar of the "PCD Firmware Downloader" nearly reaches 100% but then a message pops up saying "Download Failure, Error: NAK response".

Reason
The firmware download fails because the installed firmware (e.g. 018) first stores the downloaded firmware file to the onboard RAM (before copying the new firmware to the flash). The space required on this RAM is not sufficient for firmware versions newer than version $25.

Solution
The new firmware can only be loaded if the PCD is first switched to the "Loader State". In this state not the firmware itself but the boot loader handles the downloaded firmware file (and the boot loader does not copy the firmware to the RAM first).

Procedure for switching the PCD3 into "Loader State"

• Switch the power of the PCD on.
• On a PCD3.M5xx0
  Switch the RUN/STOP switch up and down as soon as the green RUN LED starts flashing.
  On a PCD3.M3xx0
  Press the RUN/STOP push button and release it as soon as the green RUN LED starts flashing.
• Verify that the PCD is switched to the “Loader State”:
  In case the PCD was successfully switched to the “Loader State” the “Run/Halt” LED will blink in an infinite sequence (dark-red-green-red) which is the indication of the “Loader State”.
  On the PCD3.M5xxx additionally the LED’s on the battery module will blink in the sequence “Run-Halt-Error-Halt-Run”.

Note
This procedure is only required for updating the firmware to a recent version. Once the firmware is updated this procedure is not required any more.

Remark
In case the booter version installed on the PCD is older than or equal to 024 it is only possible downloading the firmware in PGU mode using a PGU cable (PCD8.K111).

The diagnostic flag TBSY of the "Character Mode" (used for sending characters over a serial line) is not handled the same way on a PCD3 compared to "older" systems like e.g. PCD2.M170.

Symptom
If the relevant port is assigned in MC mode, the diagnostic flag TBSY is indicating that the serial port is busy sending characters. This is the case on e.g. a PCD2.M170.
This behaviour is not the same on a PCD2.M5xxx or a PCD3.Mxxxx, especially not when using a PCD3.F121 or a F2xx(x) modules. On a PCD3/PCD2.M5 the TBSY flag is not any more high during the whole time the port is busy. Instead, it is only high a short time at the very beginning of the send task.

Reason
The reason for this difference is a new manner to access the UART of the port. On older systems the characters were directly written to the UART while on the PCD3 a buffer is placed in-between. Instead of indicating the "send-state" of the UART like on older systems, the TBSY represents the state of this buffer (the size can be found at the end of this FAQ) on the PCD3 or the PCD2.M5.

Solution
This difference shouldn't lead to problem is most cases. However, in some applications the state of the TBSY is used to control e.g. the RTS signal of the line (using the instruction SOCL). In this case the communication (working on a PCD2.M170) won't work any more on a PCD3 or a PCD2.M5.
In this situation one of the following workarounds could be applied:

• Instead of assigning the port in MC0 it could be assigned in MC4 (MC4 is usually described as "MC for RS485"). In this mode the UART is managing the RTS autonomously (and therefore there is no more need to set the RTS by the user program). Note that in this case the SOCL commands are to be removed from the program!
• The duration while the RTS is to be set could be calculated beforehand (based on the amount of characters to be sent) and loaded into a timer. While this timer is high, the RTS can be set using the SOCL command.
  Note that this solution is not really a "nice" one and can only work with very low baud rates.

Notes

• All firmware versions of the PCD3xxx and PCD2.M5xxx do treat the TBSY as described in this FAQ.
• The buffer size is depending on the port used:
  PCD3 port 1 and 2: 24 characters
  PCD3 port 0 and 3:  2 characters
  PCD2.M5 port 0 and 1: 24 characters
  PCD2.M5 port 2 and 3:  2 characters
  

There is a problem when placing a communication module PCD3.F1xx and a memory module (PC3.Rxxx) on the same PCD3.

Problem
If a communication module is per example on slot 0 of the PCD3 and a memory module is per example on slot 1, it is possible that one of them will not work. If one of the modules is removed, the remaining one will work correctly.

Reason
There is a problem in the firmware. As soon as more than one intelligent module (e.g. PCD3.F1xx, PCD3.F2xx, PCD3.R5xx or PCD3.R6xx) are plugged on the PCD3.Mxxxx the detection of the module can fail.
This problem will be corrected in firmware version 031 (but is is existent also in version 030 / $31).

Solution
As long as firmware 031 is not released the two modules will not work properly together. A workaround could be to put the memory module PCD7.R550M04 directly on the communication module. Open the memory module PCD3.R550 and remove the card PCD7.R550. Open the communication module PCD3.F1xx and plug the card on this module.

the minimum firmware version for PCD3.M5540 hardware version D is V023

For the correct handling of the new flash modules PCD3.Rxxx an and the PCD3.Fxxx communication modules an "I/O module check" has been implemented in the firmware. Unfortunately this check can cause problems on older hardware versions if more than two PCD3.Cxxx modules (extension cabinets) are used.

Symptom
The communication module PCD3.F121 as well as memory modules PCD3.Rxxx do not work when more then 2 extension cabinets PCD3.Cxxx are connected to a PCD3.
It is possible that the same PCD3 was working correctly but after an update of the PCD firmware this symptom appeared. In this case with the firmware update a new I/O module check has been introduced (please refer to the table below to find out in which versions this I/O module check is implemented).

Reason
An I/O module check has been introduced for the correct identification of the modules. In this way it is possible to avoid e.g. flickering outputs of an output module if a modem is (unintentionally) configured on this I/O slot. Also flash modules can be identified properly before accessing their content.

Unfortunately this check does not correctly recognize the modules plugged in to the PCD if the PCD is equipped with an old CPLD (Complex Programmable Logic Device) version as soon as more than two extension cabinets PCD3.Cxx0 are connected to the PCD.

Solution
Upgrading the CPLD version will solve the problems as the modules will correctly be recognized by the firmware. The upgrade of the CPLD corresponds to the hardware modification 8 on the PCD3 CPUs.

Hardware version D or above
The hardware version D has a correctly programmed CPLD and will therefore also detect intelligent I/O modules if more than 2 PCD3.Cxxx extensions are connected to the PCD3 CPU. No further action is to be taken.

Hardware version
These CPUs need to be updated to hardware modification 8 (CPLD update). Once this is done these PCD3s will support all PCD3.F1xx on slot 0 and also newer intelligent modules like per example the new flash moduls PCD3.Rxxx.
The update can be done with the "Firmware download Assistant in the following ways:

This is related to a firmware problem in the PCD3 FW 018. Update to the next official version.

A firmware bug in version 018 does disable the power supply for the PCD8.K120 (Profi-S-Link cable) after a firmware download. A reboot of the controller is needed in order to get the adapter running again.

Symptom
After a firmware download to the PCD3.Mxxx0 the Profi-S-Link adapter doesn't work. No online connection over this cable is possible any more until the PCD3 is rebooted.

Reason
This is a bug of the firmware version 018 for the PCD3.

Solution
Upgrade the firmware to the next version (downloadable from the support site www.sbc-support.com). In case you cannot find the firmware there, contact support@saia-pcd.com.

Configuration:
PCD3
PCD3.F121 Port 1
or on Port 0 (just with FW $26)

Problem
When using a Sasi Slave F-Box for the configuration of channel 1 and choosing RS Type RS 232, it will generate an error and the communication will never work. Otherwise the same configuration works on a PCD2.

Reason
There is a difference in the Firmware of the PCD3 which doesn't allow this configuration

Solution
Choose RS Type Default in the Sasi Slave F-Box and it will work.

If you use the instructionlist command "TEST 10" for controlling the real time clock in the PCD3, the

systemcycletime will get down to approximitally 2 or 3 cycle. The bug will be fixed in the next FW_Version

check before Firmware download over a network TCP/IP or Modem:

before you update the PCD- firmware, check that your hardwaresettings and user program is stored in to the flash memory 

There are firmware depending differences in the handling of the Serial-S-Bus communication diagnosic flags TDIA and RDIA. Those flags are refreshed continuously by older FW versions but not by the Saia PCD® COSinus Classic PCD firmware (used for PCD2.M480 and PCD3 controllers).

Symptom
The diagnosic flags do indicate whether there has been a communication error. The flags are directly depending on the diagnostic register RDIA. If the RDIA holds any value not equal to 0, the according diagnostic flag is set.
The state of the diagnostic flags is refreshed every ms by conventional FW versions (used for PCD1, PCD2.M1x0, PCD4, PCD6).
The Saia PCD® COSinus Classic PCD firmware (used for PCD2.M480 and PCD3) does not any more refresh the diagnostic flags cyclically. On this FW, the diagnostic flags are only refreshed on a communication event (such as e.g. a SRXM instruction).

Reason
Basically the diagnositc flags are refreshed by the communication routine of the FW. Conventional FW is polling the communication routine cyclically (every ms).
The Saia PCD® COSinus Classic PCD dosn't call the communication routine cyclically but only on interrupt (e.g. the communication instruction SRXM does generate such an interrupt). This means that the diagnostic flags are only refreshed on a communication event.
The advantage of this method is a minimized CPU load due to the communication task.

Conclusion
This change of the behaviour of the diagnostic flags isn't conflicting with any description or manual. However, there could be some program code that bases on the automatic refres of those flags. In this case the code has to be adapted when intended to use on a PCD running Saia PCD® COSinus Classic PCD FW.
The adaption could be realized in the way that on reset of the RDIA (which has to be done anyways) also the diagnostic flags are reset.

There is an Error Led on nearly every PCD system that can indicate a problem on the system. Read this FAQ to learn more about the different reasons for a lit Error LED and how to find the problem causing the lit error LED.

What causes the Error LED to get lit?
There are different reasons for a lit error LED. The most common reasons are listed below:

• A problem while assigning a communication port (e.g. missing communication module or wrong parameters)
• A problem while sending an S-Bus telegram (e.g. missing port assignation or invalid data array or media)
• Invalid mathematical operation (e.g. division by zero or value overflow after a multiplication)
• Index register overflow

How to find the problem in the code/configuration?
One fast way to find the problem is reading the history entries of the PCD. This may be done by using either the Online Configurator or the Online Debugger (type "Display History"). In the History some of the problems are listed explicitely (e.g. IPM not present) for further information regarding the History entries, please refer to the PG5 Help. The chapter "Messages" contains "Halt and History messages".
If only an "Error Flag" is mentioned the next task is to find the program part where the Error status-flag is set. This is to be done by using the Online Debugger:

• Go online with your Fupla- or IL program.
• Open the Online Debugger and type "Restart Cold All CPUs".
• Still in the Online Debugger, type "Run Until Status-flag Error". As soon the Staus-flag "Error" is set, the PCD will be stopped. Therefore the Fupla Editor will jump to the page which actually is processed (only this page is part of the current Fupla file! If the Error isn't caused by this Fupla file, it will jump to any other page which doesn't cause the problem. Have a look at this page and the FBox with the "stop"-box on it and decide whether the problem could have been caused by this FBox!
  If there isn't any FBox that could cause any problems mentioned above, repeat the procedure while beeing online with the next Fupla file of the CPU).
• If you can't find the problem directly in a Fupla file, switch to the Online Debugger again. After having stopped, a line similar to the line written below will be shown:
  *001234  STH       I/O       48                                  A1   Z0     N0     P1    E1     IX      COB2
  This first number of this line indicates on which line of the code the problem happened: the last instruction BEFORE the line shown caused the problem (the error LED is lit after the problem).
• Type "Display Program <line indicated -10> Count 15". Now you can see the instruction that caused the problem: Refer to the IL instruction Set (Online Help of IL Editor SEDIT) in order to figure out what this instruction exactly does.

If a SASI instruction causes the problem, check out the following possible reasons:

• The port is already assigned (have a look at the HW configuration and search for further SASI instructions by typing "Locate Instruction SASI" in the Online Debugger!).
  Hint: Also have an eye on the SASI FBoxes you used as well as on the HMI Settings tab.
• The port doesn't exist
• The SASI text isn't valid
• S-Bus support isn't enabled in the Hardware Settings but an S-Bus assignation was executed. This won't work because in this case the PCD doesn't have an S-Bus address (which is required for S-Bus communication).

If it seems as a mathematical operation caused the error, use the online debugger to run shortly before the problem-causing part of the code by typing "Run Until Instruction-Pointer Equals <instruction line shortly before problem-line>" (note that the instruction line must contain an instruction!). Once reached this line, type "sTep". In the Step-mode, you will see the contents of the PCD medias [brackets].

Remark:
The Error LED is lit in case the Status Flag E (Error status flag is set high) and no XOB 13 is programmed. In case the XOB 13 is programmed, the Error Led won't get lit but this XOB is processed immediately.

Use caution when downloading FW to a PCD3.Mxxxx controller because it is possible downloading a wrong FW (e.g. the one for the PCD2.M480).

Once the wrong FW is downloaded follow this procedure for downloading the correct FW:

Once a FW which is written for the PCD2.M480 is downloaded into a PCD3, there is only one way to get the PCD running again:

1. PLC power on
2. Switch the RUN/STOP switch two times up and down while RUN LED is blinking. Then download the FW via PGU cable (PCD8.K111) in PGU mode.

Or "What is the difference between 0-, $- and #-firmware versions?". PCD firmware for non-Saia PCD® COSinus Systems (PCD1, PCD2.M1x0, PCD4, PCD6 and PCS) are named with 3 letters (e.g. 010, B0W or #31). This FAQ explains the meaning of these version and how to figure out which one is more recent.

The firmware version naming of non-Saia PCD® COSinus systems
In general the 3 letters (abc) are used for the following indications:

• a
  Definition of the kind version this firmware is. The possible versions are the following
  - 0xx versions are "official production versions" (010 is the first official production version)
  - Bxx versions are Beta versions which contain new features compared to the previous production version
  - #xx versions are "customer bug fix versions" of an official production FW version.
  - $xx versions (Pilot version) include new functionalities which are not yet fully tested. Therefore a $-version should only be used in field if the developement gives their ok!
• b
  The second letter defines the main production version (starting with 01x wich stands for first official production version, followed by 02x (where the 02x has important new features compared to the 01x version
• c
  The last letter is incremented for each build of the firmware (best observed for the bug-fix versions; #21 is based on the 020 firmware and contains corrections for the 020 firmware version) 

To figure out which version the base version of a bug fix- or pilot version is, have a look at the second character of the corresponding version (e.g. the "1" of the 013). This character indicates the official production version on which the bug fix or pilot version is based on.

Examples
010    is the official production version
018    is the production bug fix version of 010; no new functions
#19    is a customer bug fix version based on 018 (and therefore also on 010); no new functions
$19    is a pilot version based on 010 with new functions. The bug fixes done for e.g. 019 probably aren't implemented in this version! (the new features will be added to the production firmware versions in 020 or later.

Remark
Early versions of the Saia PCD® COSinus systems (PCD2.M480, PCD3, PCD2.M5) up to 039 were named with this system as well. In order to reduce confusion concerning features of a firmware the new firmware naming a.bb.cc has been applied (see FAQ 100741).

Some history entries introduced in new firmware versions can't be found in the Online Debugger Help nor in the online help of the Online Configurator.

Below you can find recently introduced History entries that can't be found in the Help files of PG5 versions older than PG5 1.3:

Error Messages concerning PCD1.M2, PCD2.M480, PCD2.M5xx0 and PCD3.Mxxx0 systems (SBC-NT)

The IL instruction DSP (display value on PCD7.F530 display) is not supported on Saia PCD® COSinus systems. When downloading it to a Saia PCD® COSinus system, the PCD will not go in RUN and give an error message such as "Invalid instruction" (e.g. a PCD2.M480), "Precompiler error" or "Invalid OPCODE" (on a PCD3.M5xx0 with firmware 1.10.16).

Why is the DSP instruction not supported on Saia PCD® COSinus systems?
Since it isn't allowed or even possibe to mount a PCD7.F530 card on a Saia PCD® COSinus system (e.g. a PCD2.M480, a PCD2.M5xx0, a PCD3 or a PCD1.M2xx0) the instruction for accessing the display of the PCD7.F530 is not supported by the CPU.

Remarks

• The PCD7.F530 can't be mouned on a PCD2.M170 or on a PCD2.M480 because it could cause a short circuit on the internal bus connector placed right under the slot B1.
• If a user program containing a DSP instruction is downloaded the PCD2.M480 won't run the program and the error message "Halt reason: invalid instruction" will be entered in the CPU's History.

No, for PCD3.T665/T666/T668 devices, it is not possible to define own FTP users, the Service key and the web-server password on the PG5 device configurator.

It’s possible to access to the PCD3.T665/T666/T668 with FTP by using the default FTP user and password.

Problem:

In the case of Ethernet network interruption, a diagnostic flag 'S.RIO.NameXY.Diagnostic' is set in the  Ethernet Smart-RIO manager, which indicates that communication to the Ethernet Smart RIO's (PCD3.T665 / T666) is perturbed or interrupted.
If the network interruption between the Smart-RIO manager and the Smart-RIO is longer than the timeout defined in the PG5 device configurator of the Smart-RIO then the diagnostic  flag 'S.RIO.NameXY.Diagnostic' is set to 0 automatically afterword that the network interruption is no more there.
If the network interruption is shorter than the timeout which is defined the PG5 device configurator of the Smart-RIO, then the diagnostic flag 'S.RIO.NameXY.Diagnostic' remain 1.

As a result, the master can also detect very short interruptions of the Ethernet communication.

It’s necessary to set the flag to 0 with the code attached to this FAQ

Solution:

To set the diagnosis flag 'S.RIO.NameXY.Diagnostic' to 0 by the user program, the following IL sequence can be programmed in PG5 or the enclosed code can be used:

            COB    0
                       0
; if there is a error on the Smart-RIO and the diagnostic should be set to 0
            STH    ClearESIODiag
            ANH    S.RIO.GlobalDiagnostic
            CPB    H CheckClearDiag

            ECOB

; PB to clear the Smart-RIO diagnstic information
            PB      CheckClearDiag
            STH    S.RIO.RIO_00.Diagnostic
            JR       L next
            RDP    S.RIO.RIO_00.DiagnosticID
                      RIO0_rDiag
next:
            EPB

When trying to open the symbol editor, Rio Configurator, Device Configurator or Web Editor Project this error message is displayed:

The program memory on the PCD3.T666 is suitable for communication control and online parameterization via the DALI Config FBox but not for storing the configuration data.

All media at the PCD3.T666 are volatile, means the content is lost on power down.

It's not critical for the operation because the DALI parameters are stored in the DALI ballast devices.

But also the web application couldn't be loaded on the PCD3.T666 because of the limited flash size.

Conclusion:
Use DALI on the PCD3.T666 if:
- on the PCD3.T666 only online DALI configuration via FBox and send / receive of control commands are required
   then it's possible to use up to 4 DALI interfaces on the PCD3.T666

Do not use DALI on the PCD3.T666 if:
- the full DALI functionality with ballast configuration via web pages is required
  For such cases we recommend to use a PLC with SD Flash for example PCD3.M3330 (R600 Module + 3x DALI),
  or PCD3.M5560 for up to 4 DALI modules.

Problem:
After building a PG5 2.1 project which does include smart RIO Network the error message
"Fatal Error 2004: File specified more than once: Device1.obj" appears.



Reason:
This error occurs if one of the program files of the smart RIO manager does have the same name as the smart RIO manager. (On the picture above 'Device1')

Solution:
The name of the smart RIO manager and the names of the program files of the smart RIO manager have to be different.
-> Change either the name of the smart RIO manager or do change the name of the program file of the smart RIO manager so that they are different.

When the smart RIO PCD3.T665 (or T666) with FW 1.20.36 is connected to a smart RIO Manager PCD3.Mxxx with FW 1.16.69 then the data exchange doesn't work!

Reason:
There is an incompatibility between the Smart RIO FW 1.20.36 and the older FW version 1.16.69
of the Smart RIO Manager PCD3.Mxxxx or PCD2.M5xx CPU.

Solution:
It is necessary to update the FW of the Smart RIO Manager PCD3.Mxxx or PCD2.M5xx to the version 1.20.25 (or newer) available on our support web site.
It is also possible to downgrade the FW of the Smart RIO to version 1.16.69 but we advise to update the FW of the Smart RIO Manager instead!

Remarks:
If a FW for Security Upgrade is needed and PG5 2.0.220.200 is used, please update the Smart RIO Manager with the FW 1.22.17 in attachment or a newer version if available (due to some Device Configuration download problem in PG5 2.0.220).
Using PG5 2.1.210 the FW >=1.22.10 for Security Upgrade can be also used!

No, one master can only handle PCD3.T665/T666 or PCD3.T660 Rio's.

It's not possible to mix PCD3.T665/T666 and PCD3.T660 on the same master PCD.

The PCD3.T660 is no more available.

If existing PCD3.T660 Rio's networks need to be expand with new T660 Rio's then please do contact Saia-Burgess Controls AG:

In January 2014 the COSinus FW 1.22.28 was introduced into production for the systems PCD1.M0xx0, PCD1.M2xx0, PCD2.M5xx0, PCD3.Mxxx0, PCD3.Mxx60, PCD3.T665/T666 and PCD7.D4xxxT5F.

The Ethernet Smart-RIO devices PCD3.T665 and PCD3.T666 can execute a user program.

It's also possible to make small webeditor projects on this devices.

But it is not possible to use the Alarming feature (Alarming Macro and the associated FBoxes) because the firmware of the Smart-RIO don't support this feature.

In case that Alarming FBoxes are placed in a Fupla-File of a Ethernet Smart-RIO device PCD3.T665 or PCD3.T666, then
there will be no error message shown on PG5 during the build of the project.
But after the download of the project to the Smart Automation Manager there will be an invalid configuration on the Smart-RIO and the Status-LED on the PCD3.T665/T666 will blink Red/Green and the program on the Smart-RIO will not be executed.

On the patch 1 of the PG5 2.0.220 there is a error which does lead to the situation, that data’s which are defined by the user as ‘data transfer array’ where no more exchanged between the PCD3.T66x and the smart automation manager. This error occures during compilation of the project, but doesn't corrupt the original project.

The configured I/O’s of the PCD3.T66x are exchanged without problems between the devices.

The patch 2 for PG5 2.0.220 will fix this error and will be available soon.

In case of a configuration problem with an Smart Ethernet RIO (PCD3.T665 or PCD3.T666) an according error message is displayed in the PCD history and the PCD stays in HALT. This FAQ lists the signification of the number after the "ESIO CFG FAIL" message.

The following table lists the signification of the number of the ESIO CFG FAIL nn

Remark
Please note that the first PCD firmware which provides this information is the version 1.16.69; previous firmware versions did not correctly indicate the "nn" number but only 0 or 1.

No.

While it is possible to stop the programm execution of a "normal" CPU such as a PCD3.Mxxx0 (e.g. using the Online Configurator from PG5), stopping a Smart Ethernet RIO (PCD3.T665 or PCD3.T666) is not possible.

This is a limitation of the firmware of the Smart Ethernet RIO.

After downloading the program into the manager CPU, the diagnostic Flag of the Smart RIO connected to the master CPU will be high during a short period of time, approx 0,5 second. This is not an error, it's implemented like this. 
The RIO-diagnostic flag in the user program of the manager has to be ignored during some seconds after a restart of the manager.
This can be done very easily with the help of the F-Box start delay.

After downloading the program into the manager, the RIO’s are configured again.
During the time of the configuration there is no data transfer between the manager and the RIO's.
All RIO’s are re-configured when downloading a program to manager, doing a re-start of the manager with the Run/Stop switch or from the PG5 and this is independent if the configuration has changed or not.
During the time of the configuration, the diagnostic flag of the RIO is active (because the RIO does not know that the program is being charged into the master) and the Diagnostic Flag of the RIO is "1" in the manager. 

When working with the RIO firmware 1.16.42 the Smart Ethernet RIO does not detect a missing manager at start-up of the RIO.

Symptom
The diagnostic flag "ManagerNotPresent" from the programmed Smart Ethernet RIO PCD3.T665 or PCD3.T666 is working fine if the RIO manager is present on start-up of the RIO (e.g. if the connection is removed).
But if the RIO is started without the connected master it is not detected by the RIO that the manager is missing (and the flag "ManagerNotPresent" together with all other diagnostic flags is not updated on the RIO).

Reason
Due to an error in the firmware 1.16.42 for the PCD3.T665|T666 the missing master is only detected in runtime but not at start up.

Solution
Please update the firmware of your PCD3.T665|T666 to version 1.16.47 or later.

On the programmable Smart Ethernet RIO PCD3.T66x there is a diagnostic flag available which can be used to detect whether the RIO Manager CPU is exchanging data with the RIO. However, when using PG5 2.0.200 this flag is not correctly addressed.

Symptom
When having programmed the Smart Ethernet RIO with PG5 SP2 the indicated flag "ManagerNotPresent" is not the relevant flag to detect the presence of the master.

Reason
PG5 assigns the address of the "base diagnostic flag +3", but it should be the "base diagnostic flag +7":


Solution
Please use PG5 2.0.210 for the creation of a Smart Ethernet RIO Project.

If this is not possible, you can copy the attached file "pcd3txxx.saiaxml" into the folder:
    c:\Program Files\SAIA-Burgess\PG5_20\DeviceTemplates\pcd3txxx.saiaxml

With PG5 2.0.210 generated RIOS will have the diagnostc flags correctly assinged:


Remarks

• With PG5 2.0.210 the flags are correctly addressed 
• In case the project has been created with PG5 2.0.200: Please note that the RIO must be re-created in PG5 in order to have the correction applied (because the saiaxml file copied to the project while the creation of the RIO in the project). 

In case the Smart Ethernet RIO manager is a PCD2.M5 or a PCD3 (with firmware 1.16.42) the data exchange between the RIO station and the manager is not running after a program restore has been executed on the manager.

Symptom
The data exchange between the Smart Ethernet RIO (PCD3.T665 or PCD3.T666) does no longer work after the user program from the manager station has been restored (e.g. due to a missing or empty battery).
Only PCD2.M5540 or PCD3.Mxxx0 with firmware 1.16.42 are concerned by this phenomenon.

Reason
The reason for this situation is an error in the firmware 1.16.42 for the PCD2.M5 and the PCD3.Mxxx0.

Solution
Please use firmware 1.16.45 or later on the Smart Ethernet RIO manager (if it is a PCD2.M5 or a PCD3; for a PCD1.M2 the firmware 1.16.42 can be used).

Remarks

• PG5 2.0 SP2 (PG5 2.0.200) is shipped together with firmware 1.16.42; please do not use this version on an Ethernet RIO manager (when using Ethernet RIOs)
• For the RIO the 1.16.42 can be used; they are not concerned by this problem
• The firmware which corrects this problem (1.16.45 or later) can be downloaded from the support site.

In July 2012 the firmware 1.16.69 was introduced into production for the systems PCD1.M2xx0, PCD2.M5xx0, PCD3.Mxxx0 and PCD3.Mxx60.

This FAQ lists the main differences between this firmware and the version 1.14.23 (and 1.16.69).

The main reasons for the introduction of the version 1.16.69 are the following improvements and corrections.

Firmware 1.16.69 (July 2012)

New features

• Support of PCD7.R582 module

Main corrections

• 'Resistors fails' error on the port 3 of the PCD3.M5340 (FAQ 101722)
• Wrong 'ESIO' history entry for smart Ethernet RIO’s see (FAQ 101778)
• Sporadically wrong temperature values on W745 Module if used without F-Box
• Not possible to read values from specific M-Bus devices (FAQ 101762)
• Restore from Flash (PCD3/7.R500) does not work if performed in PG5 (FAQ 101779)
• The mapped input data from the IO's are not cleared correctly
  During start-up of the PCD, instead of clearing the correct media some other random medias where set to 0
• Different enhancement and corrections on Modbus

Firmware 1.16.52 (November 2011)

New features

• Support of the M-Bus modules PCD2.F27x0 and PCD3.F27x
• Support of firmware download to F2xx modules

Main corrections

• The restore from flash works correctly also if no extended header is present (see FAQ 101680)
• Configuration of analogue modules PCDx.W525 in the Device Configurator lead to “No Response” on program download
• S-Bus password could not be set in Parity mode over a gateway station
• Heavily disturbed FDL networks could lead to a BUS ERROR of the PCD 
• The onboard digital outputs (from PCD1.M2 and PCD3.M2) were cleared even if "don't clear outputs" was selected
• Profi-S-I/O master did not work with more than 10 slaves (but "SIO FAIL 000" is indicated in the history)
• Profi-S-I/O master did not work on PCD1.M2 and PCD3.Mxx60 if the master station address was higher than 22
• The modem signal DCD on port 1 of a PCD3.Mxx60 was not read correctly

Firmware 1.16.45 (July 2011)

Main corrections

• After the program has been restored on the Smart Ethenet RIO Manager the data exchange to the RIO was no longer working (only concerns PCD2.M5 and PCD3.Mxxx0) , see FAQ 101640

Firmware 1.16.42 (July 2011)

New features

• Support of Smart Ethernet RIO PCD3.T665 | PCD3.T666
• Media mapping data (for Ethernet RIO and local Media mapping) is cleared at the same time as the I/O reset is done (including Power-on)

Main corrections

• When using a slow connection for an FTP transfer of big files the transfer could fail due to a timeout in the send process
• Change the backup file name to: "progname_yymmddhhmm.sbak" (before the year was in the middle, making sorting more difficult)
• PCD as Modbus RTU server (and a Siemens RTU is master) can stop answering requests after hours of operation
• PCD as Modbus IP client could go in halt due to a Bus Error if an invalid Modbus frame has been received (with only the Modbus IP header but no data)

Firmware 1.16.27

New features

• Program backup to file system including media content, see FAQ 101622
• Extension memory backup size to flash has now a fixed size (256 kByte) without re-ducing the available memory for the user program, see FAQ 101623
• The maximal length of an SMTP user name and password is extended to 128 characters, see FAQ 101590

Main corrections

• If the file system of a blue memory card was filled to the last byte, it was possible that the file system was no longer available after a reboot, see COM11031 / FAQ 101559
• If the SMTP servers stopps working while an Email is transmitted, the SMTP client could block, see FAQ 101610
• The HMI Editor option "Support all media types" was not supported on the PCD1.M2120, see FAQ 101549
• CSF InitDBItems could overwrite the subsequent DBs
• USB connection failed sometimes after a firmware download
• Answer to FTP command CWD returned the code 250 instead of 200
• Download in Run of changed Steps or Transitions could lead to “INVALID OPCODE”
• The IL instruction WTIME wrote an impossible time when called with an invalid value

Hardware compatibility of firmware 1.16.27

The firmware 1.16.27 requires a PCD equipped with 4 MB onboard flash (like the firmware 1.14.23). Therefore the minimal hardware versions for installing the 1.16.27 and later are:

For PCD3 systems older than listed the firmware 1.10.61 is the last firmware which can be installed on these systems. This firmware is and remains available on the support site in parallel to the 1.16.27.

Remarks 

• When updating from 1.10.xx or 1.14.xx
  Please note that the user program, user program backup as well as the communication settings are lost during the firmware update from 1.10.xx or 1.14.xx to 1.16.xx 
• BACnet applications
  The BACnet firmware compatible to firmware 1.16.42/45 is version 1.16.41. Please use the “Latest BACnet Firmware Package” (version 2) from the support site for PCD1.M2, PCD2.M5 and PCD3 systems in BACnet applications as usual (link below).

This Ethernet RIO can be equipped with special modules for communication and fast counting features.

Following modules can be plugged on a PCD3.T666:

• PCD3.F27x (M-Bus)
• PCD3.F1xx (Communication modules for slot 0)
• PCD3.H1xx
• PCD3.F261 (DALI)
  

We currently support the following PCD3.F1xx modules (slot 0):
PCD3.F121 (RS-232), PCD3.F110 / PCD3.F150 (RS-485/RS-422), PCD3.F180 (Belimo MP-Bus)

With the PCD3.T666, it's also possible to use the onboard RS-485 communication port. On the contrary, this communication port isn't supported on the PCD3.T665.
