Years ago a commissioning tool for some motion modules (e.g. PCD2.H32x) has been developped and was set to the beta phase. Due to a lack of interest and feedback from the market this tool was never officialized and is not supported any more.

What was MotionX?
The software packet MotionX (PCD8.H50000E) has been created for commissioning complex motion modules such as the PCD2.H32x. The software was designed to support the user to find e.g. the optimal PID settings by visualizing graphs of recorded units such as acceleration, speed etc.
Another feature was a code generator for moving the concerned axis without writing all the initialisations by hand.

Why was MotionX never officialized?
The following reasons were conclusive for the decision not to officialize MotionX:

• During the beta phase which was extended to several years only very little customers were interested in this product (Very weak demand).

• Since the use of the software did also influence the performance of the PCD itself many customers prefered to optimize their installation by the use of an oscilloscope instead of MotionX.

• The usage of the software was rather complicated. The feature to generate code was only used by few beta testers.

• The low demand did not justify the effort to officialize the software.

Can MotionX still be used as "unofficial" software?
Since MotionX was never realized it is not maintained any more and therefore it is not compatible with the latest PG5 versions. It is only compatible with PG5 1.2. This leads to the fact that it can not be used in parallel to a recent version of PG5 (which was the initial aim and target). We therefore don't recommend to use this tool any more.

How to commission a H-module then?
We recommend finding/adapting the motion parameters of a motion module/system by the use of an oscilloscope which is connected to the output of the module. The resulting graphs can be interpreted in the same way as the ones created by MotionX and are more exact.

When using the commande function which allows for example the writing of the hardware clock from PLC to Terminal PCD7.D7-- over Ethernet connection the 2 first words are swapped.

Problem
If the PCD8.K120 is connected to the bus, the bus is disturbed sometimes. The communication stops for a moment.

Origin
Due to the design of the Profibus connector all GND connections are on PIN 1 to 5 (all on the same side of the connector), on the other hand PIN 6 to 9 are the bus signals. If PIN 6 to 9 are connected first, the bus will be disturbed.

Solution
To avoid the disturbances on the bus please pay attention that PIN 1 to 5 are connected first (plug in the connector with a light tilt to one side so that the PIN 1 to PIN 5 side of the connector makes the first contact).

There are several point that can cause problems when using the Profi S-Link cable PCD8.K120.

Recommended firmware and PG5 version:
FW 023 or higher
PG5 1.4.100 or higher

With FW versions below 023 the power supply on the Profi S-IO connecter was not working.
Some improvments regarding the use of the Profi S-IO are implemented in PG5 1.4.100 or higer

Important point:
The Profi S-IO network needs termination resistants on both sides of the network, otherwise the connecting of the Profi S-Link adaptor will interrupt the communication on the bus. Note that if you are using Profibus connectors with internal termination resistant they have to be powered (plugged) otherwise the termination resistant is not active.

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.

It is important to distinguish between a temporary IP address that is stored in RAM (which is foreseen to be able to download a configuration to the PCD8. K120) and a configured IP address that is stored in Flash-EPROM. If your unit "forgets" the IP address during a power down you probably only assigned a temporary IP address, but didn't download a correct configuration.

To power on the PCD8.K120 Profi-S-Link adapter you have to enable the Profi-S-Bus of the corresponding port on the "Profi-S-Bus" folder of the PG5 Hardware settings and you have to downolad the Hardware settings to the PCD.

The PCD8.K120 Profi-S-Link adapter needs to be powered with 24VDC.
The 24VDC for the PCD8.K120 is available on the PIN # 7 of the 9-pol D-Sub connector of the PCD2.M480 /PCD3.M where you connect the PCD8.K120 adapter.
To switch on the 24VDC on the Pin # 7 you have to enable the Profi-S-Bus of the corresponding port on the "Profi-S-Bus" folder of the PG5 Hardware settings and you have to download the Hardware settings to the PCD.

For going online with PG5 using PGU mode a special cable (PCD8.K111) is needed. What is the difference between a normal crossed cable and the PCD8.K111)?

The important thing is that the pin 4 (PC side, DTR) is connected to pin 6 (PCD side, DSR).

When going online in PGU mode, this signal is set high and causes the PCD to unassign the port 0 (if it was assigned before) and reassign it in PGU mode. Therfore it always is possible to go online in PGU mode.

Remark
Please note that in case the option "Full RS-232 handshaking on Port 0" (for modem connections) is checked in the hardware settings of a PCD3.M5 or a PCD2.M5, the PGU signal (DSR) can no longer be detected. In this case, the only possibility for going online in PGU mode is using the USB cable (or using an S-Bus PGU port which had been configured in the hardware settings previously). 

The display has a frozen screen (can be black if in standby mode) and can't be operated. After a powerup the project's start page is displayed but the touch screen doesn't respond, because the calibration has been lost!

Solution
The firmware (PCD7.D761) needs to be updated! The firmware update is done when downloading the project to the panel when the option "Update operating unit firmware" is activated.
If the display can't be forced in transfer mode (download mode) it might be necessary first to recalibrate it as explain in FAQ 100868 (see link below).
Use the latest PCD8.D81W 5.18 version which contains the newest FW!
If you haven't le possibility to use this version and you have the version 5.12 you can also add the new Fw in attachment. So, please execute the following steps:

• Download the files attached to this FAQ and unzip the archives.
• Copy the firmware files "VT155W.BIN" into the following folder:
  "C:\Program Files\SAIA\PCD8.D81W_512\\firmware\"
• Open the VTWIN project, compile it again and download it to the panel and active the download option "Update operating unit firmware".
• When the download has finished, after a powerup of the panel, please verify that the new firmware version is: 1.13.

New: Use the actual programming tool version PCD8.D81W V 5.18 which contains already the new firmware version. So no need to copy the fw files in attachment!

On a Profi S-Bus network when PCD7.D76_ terminals are connected to PCD3.Mxxx or PCD2.M480 PLC's over Profi S-Bus, the terminal loses the communication after some time and get even frozen. This problem is corrected in the new boot, FW and driver. The PCD8.D81 V 5.09 is needed , the attached files have to be copied in it (see procedure below).

It is also necessary to update the PCD3.Mxxx and PCD2.M480 FW with the version PCD3.Mxxx_023.blk / PCD2.M480_$27 or newer! Ask the PCD technical support or your representation for it!

Attached you can find the new boots, firmwares and driver that resolve the problem with the Profi-S-Bus network.
The booter file " BT155MTF" and BT525MTF have to be copied in the following folder
C:\Program Files\SAIA\PCD8.D81W 5.09\Boot

NEWS: In the latest version PCD8.D81W V 5.12 contains all thoses updated FWs, drivers and boots! Ask the technical support or your representation for it!

It is possible to convert all the variable from a S-Bus driver to Ether S-Bus driver if an existing project has to be used on another terminal type (e.g. PCD7.D786 convert to PCD7.D786ET)!

Hereby the procedure to convert your project from VT585W (PCD7.D786) rev 4 to VT585WB ETH  (PCD7.D786ET) in order to save the addresses of the project variable when you change the driver from SBC S-bus to SBC Ethernet S-bus:

Since the version V5.07, it is possible to import the global symbols from a Saia PG5® project. Because the online help doesn't explain the import procedure correctly, you can find a corrected version attached to this FAQ!

If you need an update of your VTWIN version to this beta version, please contact your local Saia-Burgess Controls AG representative.
The beta version 5.09 is now available!
