I take care of several draw bridges and have a problem with our gates, when there is an electrical problem the operators have to crank these gates back up manually, the problem is they will crank to much or to little and not know it till later. Often the drum limit will roll back over and force the traffic signals red or not allow some other function to occur. So I want to add a pilot light in parallel with a plc input. At the gate I have two cams, one raised and one lowered indication circuits that go back to plc inputs is it possible to add a pilot light in parallel with the plc input or will this cause problems. I'm looking for a solution with the least amount of wiring to pull off so I wanted to see if this could be done. They PLC system is an PLC-5
