Yes, this works (at least we have it running with Wago PLC and Beckhoff I/O), but the concept works. You need 2 PLC's with at leat 3 network interfaces. And 2 switches (can be unmanaged). See the attached simple diagram for the solution.

Hi! thanks for reply. We tested the configuration you proposed as well; however, when the cable between the controller and the switch was disconnected, the Active and Standby roles were swapped. Did you observe the same behavior in your configuration using WAGO and Beckhoff?

Hello, I think I understand: On my debian gateway I have done: sudo cmu --list cmu - CodeMeter Universal Support Tool. Version 8.30a of 2025-May-06 (Build 6885) for Linux/ARMHF 64-Bit Copyright (C) 2007-2025 by WIBU-SYSTEMS AG. All rights reserved. List all locally connected CmContainers: - CmContainer with Serial Number 130-XXXXXXXX and version 3.00 (empty) - CmContainer with Serial Number 130-XXXXXXXX and version 3.00 (locked) Result: 2 CmContainer(s) listed. The licence has been activated with a computer Name, but the guy who did it make a mistake in the name, so he changed it after to have activate the licence. I think this has created a second container. The licence is actived on the other container.
