I am troubleshooting a PLC 5 hot backup system in which the switchover is not taking place. I noticed that one PLC 5/40 processor has firmware revision K and the other revision H. Is this an issue for hot backup? Do both the processors have to be of the same revision? Any inputs on this will be appreciated.
