I have a Panel view plus 1250 here that is being used to remotely monitor a water/utility process. There are numerous alarms and warnings that pop-up to help the operator, but over time the operators have began ignoring them because "most of the time", they are non-critical or they pop-up during a routine water change. There are also times that a critical warning or alarm occurs and by the time the operator realizes this it is too late/line goes down.
The HMI is a couple hundred feet away from the PLC. I want to add a fault light on top of the HMI enclosure that will only turn on for critical alarms/warnings. Is there an easier, cost effective way to do this besides wiring between the PLC and HMI? The wiring itself isn't a problem, just getting above and around equipment between them.
