Given I have a PV+ and compact logix controller, I need to program three agitators to start in a specific ordered determined by the operators inputs via the PV+. The operator will determine who goes first, second and third (kind of a priority). I was thinking of setting up a register for each agitator where the priority would be stored and the PLC program would act accordingly. My question is how to make sure there is only one priority one, one priority 2 and one priority 3? Once the operator picks a priority, it cannot be used elsewhere. Is there an easy way to accomplish this?
