Post by ewi04 on How to upload application file to remote controller (offline) ? CODESYS Forge talk (Post)
Thank you very much for your time and replay! Sounds like a good idea. Unfortunately, I have no other option to run the code from the running plc. So, I can’t stop any services. If anyone has the same problem, I've gotten a little closer to understanding it: Sometimes the copied files are empty after the restart. The update code checks if there are any empty files. Before I turn off the device, everything is okay. But after starting, some files are suddenly empty and that cause the problems. I don't know why this happens.

The stepper supports CiA402 maybe I can use a CiA402 library to controll the stepper motor. Has anybody experience with that?
