CPU Unit Allocation DM Area Settings
Setting is written from the Programming Device (a Programming Console or
CX-Programmer) directly into the allocated DM Area (PLC Setup) of the CPU
Unit. After the setting is written, it becomes effective by turning the power ON,
restarting the Unit, restarting the communications port, or execution of the
STUP instruction.
