Hi @MarkovicMisa, I marked Alex’s answer as a solution because I think this is the only solution for your use. I am sure you have to update your version of the OPCUA CS module. Please update us anyway. You can for sure continue in the discussion and change the solution reply as needed.
thank you very much for your help and quick responses.
Updating the OPC UA Client/Server package was indeed the key. After reinstalling Automation Studio and upgrading the OPC UA package, the PLC stopped rebooting and the OPC UA configuration works correctly now.
I am still working on the UaExpert side, but the original reboot issue has been resolved.
