Our application sometimes misses the PLC's brief request for part inspection. I'm reviewing that ordinary, non-safety handshake for Fairino FR10 in a workshop inspection station awaiting commissioning, with a reference plate in the setup.
Signal ownership and clearing conditions aren't clearly documented. The safety functions are independently engineered and separate from this job interface.
Reviewing a missed request without confusing it with rejection - part inspection

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.
