Our FR5 CNC handover plan has two events hiding in ready. Machine supplier means request received; integrator means loading area available. How do I get the ordinary job interface agreed without either team winning by renaming the other team's signal?
Walk through receipt while the area remains unavailable. Define separate event meanings, sources and set/clear conditions, including timeout and restart; keep ordinary coordination distinct from safety permissions.
Sent that example to both teams. It makes the disagreement concrete: receipt can happen before availability. The integrator is identifying a separate source for the later condition. No jointly approved interface yet.
