[Se...] Posted August 7 Share Posted August 7 Hello, My add-on needs to run a blocking GOM command while a Modbus polling loop keeps running for a two-station workflow. Since GOM commands can only run on the main thread, I tried using multiprocessing.Process for the blocking scan. This works in the edit mode, but after the add-on is locked and packaged, the child process fails with ModuleNotFoundError when importing the add-on module. Using a temporary .py file with subprocess is not an option because it would expose the source code. I also tried threading, but it sometimes causes unexpected crashes in software, so I would prefer not to use it. Is there an official way to use multiprocessing or a separate Python process in a locked add-on without exposing the source code? If not, what is the recommended way to handle this kind of two-station parallel workflow? Link to comment Share on other sites More sharing options...

[Ma...] Posted 1 hour ago Share Posted 1 hour ago Please sign in to view this username. I've studied services and those are mainly for sharing functions across many add-ons. But it's like for calculations - not for dialogs. If anyone needs a function, which should return calculated result defined by parameters, then this can be used. But i don't think you can hide code or use compiled python code. At least i didn't try "pyc" file Link to comment Share on other sites More sharing options...
