We have a very long conveyor that has multiple Emergency Stops along its route. Over the years, additional equipments were added along the conveyor's route adding more E-stop to the conveyor.
The problem is, whenever someone pushed in a E-stop, we had to search all along the route to find out which E-stop was pushed. This can be resolved by adding one additional pair of input wiring to the PLC and along with a HMI of some sort to indicate the location and status of each E-stop. The HMI would be easy but I hate the idea of running so many pairs of wires for such long distances.
Is there some technical solution out there?
