So I got my ML1100 up and running last night, and tonight Im trying to connect an analog in/out module 1762-IF2OF2. The problem is that the green power on light on the module is not coming on consistently with the PLC. I can plug/unplug the PLC 10 times, and the module will only come on maybe 2 times out of the 10. This is causing a fault code saying that the PLC isnt recognizing the module that Ive configured in the logic. Is this a bad expansion module? I have +5v, -5v, and +24v coming from the pins on the ML1100 expansion plug so I know its sending power to the module. It was a used ebay purchase so Im not surprised if it is a bad module, but its rather disapointing.
