I have never seen a "MOVE" command on a PLC, but every PLC I've ever worked with has a "Copy" command, although some call their "COPY" command "MOVE".
BTW, which PLC are you referring to?
The PLC I am referring to is a Klockner Moeller
Easy819-DC-RE and I am using the EasySoft6 software. I want to move a number value into a comparator instruction.
