We have L72 controller of Rockwell make with 4 nos. analog inputs from pressure transmitters. Due to break in cable connection OR transmitter fault,etc. bad value shows in PLC program as -200 which causes automatic startup of standby equipments.
Is there any method by using i can avoid bad value coming from transmitters (non-smart) so as to prevent auto startup of standby equipment?
I checked in Controllogix PLC but could not identify such FB with which requirement can be fulfilled.
