Allocation DM Area Settings for CPU Unit
Settings are 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 settings are written, they become effective by turning the
power ON, restarting the Unit, restarting the communication port, or execution
of the STUP instruction.
The following table shows the words allocated in the DM Area and the set-
tings.
