Dear All,
I have been using 5561 CPU with redundancy, Few days ago, I have seen the message Disqualified on RM module of secondary PLC. and i can see controller is showing alarm for redundancy is missing, But there is a module 1756-EN2T installed on secondary PLC which is connected with HMIs station, has error for Led NET is blinking green.
My question is
Is it happened because of RM module failure, or it could be other issue. How can i ensure the exact issues.
Pls note down I am New to Rockwell, Earlier i have been experienced with siemens products.
Your kind support will be highly appreciated
