I'm reviewing our non-safety job handshake for sample verification with Fairino FR5 in a training inspection cell with an ordinary job interface, using a reference plate. The PLC sends a brief request, and our application sometimes misses it.
I can't find anything clear about who owns each signal or when it gets cleared. Safety functions are independently engineered; this is the ordinary job interface.
A request pulse disappears between polls (sample verification)

@RobinArcher0425 Can you compare the request trace with your application's polls? Also note which side clears the request.

Our trace shows it rising and falling between two polls. The PLC clears it without an observed acknowledgement. No wonder the application misses it.
