Two questions really:-
1. How do you force a redundancy switch-over from within the PLC code? I am struggling to find any information on this but believe it is possible.
2. This is related to the first question. For some reason when my secondary Ethernet module (talks to scada) is removed from the primary processor chassis switchover doesn't occur. This module is not currently connected to the scada and not sending or recieveing commands. Not sure if this makes a difference.
Setup. Each processor chassis consists of:-
1756-L71 processor (running on V24.52)
1756-RM2
1756-EN2TR (DLR)
1756-EN2TR (SCADA)
Any help would be much appropriated once again.
