Hi nano, thanks for your answer, it took me some time but finally it works - the make file provided by the SDK takes care of practically everything :)

Raspberry Pi 4 Codesys 3.5.20 sp3 Codesyscontrol 4.15.0.0 based on sdk 3.5.21.0 Hi all, I have found a lot of topics but none of them get me on the right path, therfore i started a new post. Usually i work with plc based systems and codesys but now im trying to create an project where i read out a serial data stream from an arduino connected by an USB port. in the future this need to be more arduino's but first trying to make it work with one I had my program working but i needed to update my raspberry pu to the letest version to get the mimo screen working. Now i tried several rules in the CODESYSControl.cfg and/or CODESYSControl_User.cfg files but i never get the com port opened. At this moment i have an file CODESYSControl_User.cfg with entry: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 I tested the connection with minicom and the data runs fluently. Can somebody help me with what could be wrong? the com port states ERROR_UNKNOWN 5004 when i tried to open.

Problem gelöst: die Größe von Memory habe ich reduziert und die Basis vom Retain Bereich entsprechend nach unten verlegt. Dann konnte ich die Größe vom Retain Bereich um den Betrag vergrößern. Jetzt läuft alles wie es soll.

Hello, Sorry for digging this topic up, but the bitbucket link does not work anymore. Have you changed the location @mondinmr ? I would be really interested in your project, even if you did not finish it. Thank you for your time, BR

You should not use the "open dialog" to change the value. Instead use the input configuration "Write Variable" to change a variable value in the visualization. in the setting of this input command, you can choose the Input type (select dialog).

Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
Thank you for your input! What I'm ultimately trying to achieve is automated test execution as part of a CI/CD pipeline (e.g. in GitLab or Azure DevOps). For this, I need to: Open a CODESYS project via script Build the project Run the Test Manager tests from a .TestRepository.xml Collect test results (e.g., pass/fail + a report) Exit with a proper return code (for pipeline success/failure) To integrate this into automation, I’m using the CODESYS scripting engine via Python (headless), but the issue is that the get_testmanager() function isn't available on the project object — even though Test Manager is installed, licensed, and works interactively in the IDE. Are you suggesting that I should: Use the Test Manager GUI to script the logic with its internal scripting language? Or is there a way to launch the Test Manager in headless/scripted mode, while still being able to control things via Python? If there's a supported way to automate tests with the Test Manager using scripting, especially from pipelines or headless environments, I’d really appreciate any pointers or example workflows. Thanks again!

Update as of 2025: This function (IECStringUtils.FormatDateTime) doesn't make any sense there isn't any parameter that accepts a Date_Time value. I have no idea what's purpose even is. I am going to use StuSprintf from the StringUtils library for this purpose.

Hello If you uncheck 'Auto restart Communication', it will try once and never again. You can manually reset the slave if needed : Slave.xReset (or something similar) Or I have a ModbusRTU library if you want to try it.

Does anybody have a schema.sql so I can create the table myselves? Does anybody know to generate more logging information so I can see the tables names? Do we have a level option or something like that?
