Hi everyone,
I have a quantum plc with modicon i/o drops. I am a running modbus plus network. Right now I have several problems.
1. One of my 140 DDI 353 input modules has a constant 20 volts on all terminals.
2. Two of my control panels, from Automation Displays Inc., have no indicator lights. The switches open and close doors but the indicator lights do not work.
Any suggestions??
Thanks
