How to show control changeover to customer from primary to coprocessor BMEH582040S

Assuming you mean the changeover between the CPU and the BMEP58CPROS3 co-processor (and not the Primary and Hot Standby CPUs), there is no changeover mechanism between them. The safety co-processor executes the same safety logic in real time using the same input information, independently of the CPU. Both the CPU and the co-processor must arrive at the same result before output commands are validated and passed to the safety I/O modules.

If you want to monitor the changeover between Primary and Standby in a Hot Standby system (standard or Safety) , you can monitor the ECPU_HSBY_1 variable.
