I am using a Micrologix 1100, part number 1763-L16BWA. I have been able to get the input side working, but can’t seem to figure out the output side. I also have an 1762-IQ8OW6 extension.
I have some simple lights that “light up” when I connect them to the DC + and DC- terminals so I know the lights work.
I have created a simple ladder program that has one rung for each output on the PLC and each output on the 1762-IQ8OW6 extension. Each rung has a separate bit that turns on or off that output:
All the outputs on the PLC and the extension are activated:
However, no matter how I have tried to wire it, I can’t get the light to turn on through the output terminals. I have connected the VAC/VDC terminal in the output to DC+ and then connected one end of the light to the other output terminal and the other end of the light to DC-. I have tried the reverse.
I have tried wiring all 12 of the output terminals.
I have watched lots of videos, but they are all doing more complex things. It seems like everyone knows how to do this but me.
