We are slave system we are running the plc either hardwired or profibus according to selection. We have six Pumps starting fro master plc. If we start one by one upto 5 pumps are running if we start any pump in last (i.e. sixth) CPU Going to stop Mode with 5 min. We have Changed All analog card and including CPU its going to stop mode. For Your information we have downloaded OB121, OB122 Block also but it is still going to stop mode. Set point for valve we were getting from master plc.
Finally we have changed analog input (set point to valve) in the rack 1 Slot 4(Replaced from Slot11) it was run for six hours then same problem came. What could be reason?
