Hi, We are investigating available libraries and frameworks for automated PLC unit testing in Schneider EcoStruxure Machine Expert. Specifically, we are looking for: Assertion libraries or test frameworks compatible with Machine Expert CODESYS‑based solutions that are not TwinCAT‑specific Any official or community‑recommended approach for unit testing FB/FC logic offline We have found several open‑source examples, but many appear to be TwinCAT‑dependent and therefore not compatible. Are there any known libraries, best practices, or recommended approaches for implementing unit tests in Machine Expert? Thanks in advance.

If the Professsional Developer Edition (which includes the Test Manager) is not supported by Schneider, then an option is to use the Open Source Unit test framework. See: https://forge.codesys.com/lib/counit/home/Home/

Ok, I think I understand. The problem is my language-setting being "swedish". I will check if I can switch to english. Update/confirmed. Change LANG to en_GB, this enabled the architechture to be correct and the control SL again to appear and to be possible to be updated. Thanks!
