Allocation DM Area Settings for CPU Unit
Settings are written from the Programming Device (a Programming Console
or CX-Programmer) directly into the allocation DM area (system setting area)
of the CPU Unit. After the settings are written, they become effective by turn-
ing the power ON, restarting the Unit, restarting the communications port, or
execution of the STUP command.
In the following, the channel numbers of the allocation DM area and the set-
tings are shown.
m=DM30000+100 × unit # (CH)
Compatible Host Units
Some models and series of OMRON PLCs have the NT link (1:1) function
built in. With CQM1H PLCs, a Serial Communications Board can be added to
provide 1:1 NT Link communications. Some C200HX/HG/HE(-Z)E CPU Units
can be connected by the NT link (1:1) method by installing a Communications
Board.
Check the model and series of the PLC against the type of CPU Unit before
making the connections.
