DM Area Allocation Settings
From the Programming Device (i.e., a Programming Console or CX-Program-
mer), write the settings directly to the CPU Unit's DM Area Setup Area. After
the settings have been written, they will be enabled when the power supply is
cycled, the Unit is restarted, the communications port is restarted, or a STUP
instruction is executed.
The DM Area words that are allocated and the contents of the settings are
given in the following table.

Compatible Host Units
Only OMRON’s CS/CJ-series PLCs support the high-speed 1:N NT Link
through RS-422A/RS-485. The high-speed 1:N NT Link must be established
through a Serial Communications Board/Unit. (Even CS/CJ-series Units with-
out the “-V1” suffix can be connected via a high-speed 1:N NT Link by mount-
ing a Serial Communications Board/Unit.)
Be sure to check the model number of the PLC and Board/Unit before trying
to establish the high-speed 1:N NT Link.
The following table shows which CS-series PLCs can be connected to an
NT631/NT631C with the high-speed 1:N NT Link through RS-422A/RS-485.
