I'm reviewing our non-safety job handshake for fixture inspection with Fairino FR5 in a PLC-coordinated fixture inspection cell, using an inspection coupon.
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.
Where should request ownership be written down? - fixture inspection

@OmarCarter1013 Does your trace show when the PLC request is raised and cleared relative to application polls, including which side performs the clearing?
