Redundant AB PLC5 - Switchover by Logic
Forcing switchover of AB redundant PLC5 by logic.

Goodmorning everyone,

I'm working on a control system with redundant PLC 5 through the 1785-BCM modules.

The system is interfaced via 3100-MCM modules with an Intouch HMI.

I cannot find a way to command from HMI, and then from logic in the PLC, a switchover between controllers.

Do you have any suggestions?

Thanks in advance.
