No, the LonWorks devices PCD2.F240, PCD3.F2400 and PCD7.R582 are no longer available.

The production of the LonWorks interface devices PCD2.F240, PCD3.F2400 and the LonWorks memory device PCD7.R582 was discontinued at the end of 2021 and the devices are no longer available.

As a replacement, we recommend the usage of BACnet.

It is depending of the PCD/PCS used, the rest of the programme and of the memory available:

PCD2.M170/M150 until1000, advised 500 -700        
PCD1,PCS1 advised maximum 400-600         
When Extended Memory isn't used (not advised du to the speed) we can used normally 50 - 150 SNVT. 

In the system catalogue there is a schematic of a PCD connected to a BACnet/IP network which could lead to a missinterpretation. Although BACnet is supported by a PCD3 or a PCD2.M5xx0 and LON on IP will be suppored in future, it won't be possible to run both stacks on the same PCD at the same time.

Why is it not possible to run BACnet and LON at the same time?
This limitation is caused by the rather high usage of ressources (performance and memory) from both these firmware extensions. While there is no problem to run one of these firmware extensions, the currently available PCD systems do not support both firmware extensions at the same time.
It is intended to provide a solution for BACnet and LON on the same PCD but this requires a new PCD system in future.

Why is this schematics printed in the System catalogue?
The aim of this schematic is to show that both protocols are supported, but not to indicate that both protocols can be used at the same time. If the PCD is running the LON stack, the other communication could e.g. be Ether-S-Bus.

How can I realize a gateway from BACnet to LON with PCD systems?
The currently only solution is the realisation with two systems, which could e.g. be connected with Ether-S-Bus.

If a PCS1 does use at the same time a serial communication with > 9’600 baud and the user wants to make a binding with the LonMaker then it’s possible that the binding will not succeed and on the LonMaker there is an error message:

“The device is application less or is not associated with a program record”

To solve the problem and to be able to make the binding either you have to switch off the serial communication or to use a baudrate <= 9'600 baud.

The reason of the problem is, that the PCS1 has not enough CPU power to perform simultaneously a Lon binding and a serial communication with > 9'600 baud.

The PCD must be equipped with a PCD7.F8xx module and RAM is to be mounted on the memory socket, with the "memory use" set to RAM (the binding does not work with a Flash).

The RAM Text and RAM DB have to be set to the following range:
- PCD1: 2000-2499, 2500-2599
- PCD2: 4000-4499, 4500-4999

If 1 Mbit RAM is used the user memory should soon be too small, it is recommended to use 4 Mbit RAM.
For a PCD1 we recommend to use maximal 400-600 SNVT.
For other PCD the theoretical limit is 4095 SNVT.


How to save the binding in a Flash?

Follow these steps:
¨      Bind the network using RAM on all PCD
¨      Execute an upload dBx and rebuild (all)
¨      Replace the RAM with flash on all PCD at wish
¨      Download the program again, this goes now in flash

Problem
After compiling and download of a LON IP project with PG5 2.1.100.0, the error LONIP FAILED 1007 is shown in the history of the PCD and the PCD goes to halt.
This problem is due to a bug in the LONIP configurator of PG5 2.1.100.
With PG5 2.0.220.200 this problem was not yet present.


Solution
Install the patch 1 for PG5 2.1 that can be downloaded from the Support homepage in the section Software / PG5 2.1 Suite.
