[Allocation DM area settings for CPU]
Settings are written from the peripheral tool (a programming console or CX–Pro-
grammer) directly into the allocation DM area (system setting area) of the CPU.
After the settings are written, they become effective by turning the power ON, re-
starting the unit, restarting the communication port, or execution of the STUP com-
mand.
In the following, the channel numbers of the allocation DM area and the settings
are shown.
