<div class="markdown_content"><p>Thanks...</p> <p>This is very helpful, however the output contains no COB ID Information or position in message.<br/> Can you suggest some way of extracting it (Some .xml relational structure or something???</p> <p><img alt="IMG: Node_Properites_COdesys.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=913"/></p></div>

For the import, the command is <span>["device", "importcsv"]</span>.</p> <p>HTH, Markus</p> <p>PS: The execute() function on the commands is intentionally not documented, but having a "backdoor" in cases like yours where the scripting API is missing functionality are exactly the reasons why we implemented it.</p> <p><img alt="IMG: mapping" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=581"/></p></div>

<div class="markdown_content"><p>Is it possible to get access (Python/ Other) to CANbus Mapping information at compile time in Codesys 3.5?</p> <p>In our case, we would port it to a Vector(CANalyzer) .DBC file, but it could be ported to any 3rd party format, but csv, xml would also be useful.<br/> There are a number of 3rd party vendors that can use such files directly.<br/> The following and many others use .DBC<br/> 1. SCADA- Matricon/Honeywell<br/> 2. CAN Bus analyzer: Vector CANtec, <br/> 3. Telemtry: LHP Telematics<br/> 4. Data Acquisition: HBM</p> <p>It could also used to create customer documentation (PDF)</p> <p>Perhaps something similar for EtherCAT, UDP Net Var etc...</p> <p><img alt="IMG: CAN_Mapping Table.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=580"/></p></div>
