Ok, great! Thank you! This makes sense!

Okay, so do I understund this correctly? On the built in input module the two COM connectors has to be connected to the ground but on the OD214 output module the COM connector should be connected to whatever voltage you want it to output and the 0V connector shold be connected to the ground/0V?

I attached a sketch of my wiring. I hope it helps.

Hi! I am very new to PLC:s and I now have a pretty simple question. I have a CQM1H PLC with a OD214 module connected to it and I have written a simple program making point 01 on the output module turn on when point 00 on the built in input module gets a signal. It looks like everything is working, the indicator for point 01 on OD214 turns on when the signal reaches point 00 on the built in module but when I measure the voltage on point 01 it shovs only 0V. Why is this the case I don't understand what the problem is. I might have done any stupid mistake as I am really new to these things :)
