Can anyone tell me if the output indicator LEDs on a 1746-OB16E will illuminate with no load on them?
My technician is telling me the PLC outputs aren't working. They were working previously for longer than I've been alive. My usual first step is to have them look at the output indicator LEDs, if they are turning on the problem is wiring, if not I will connect to the PLC. My company normally uses relay outputs and those little dummies will close their contacts whether theres a load or not. The modules in question are transistor outs so I'm wondering if they only illuminate with a load connected, I believe I have seen this on a different output module before.
The blown E fuse indicator is not on.
Thanks in advance!
