The MOV instruction is used for data transfer between the C500-AD101 and the
CPU Unit in four-word operation mode.

Always set four-word operation if the READ and WRIT instructions cannot be
used because the CPU Unit does not support READ and WRIT or if the
C500-AD101 is mounted to a SYSMAC BUS Slave Rack
Using the MOV instruction, I/O refresh is matched to the CPU Unit cycle time.
