Hi! Im a newbie to the plc thing and need some help wiring up my "first PLC" 
The plc I have is a AB micrologix 1000 it runs off a seperate 24dc supply. I've got all the inputs sorted out. But im concerned about the grounding terminal on the plc its self. Do I wire it upto the power supplys earth which is in turn connected to the mains earthing system. Or do i wire it to the negative part of the powere supplys input as is done in cars?
This is proably a really dumb question but please im just starting
