Using the High-speed NT
Link (1:N) Method
Connecting to the Host’s RS-422A/485 Port
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-series Units without
the “-V1” suffix can be connected via a high-speed 1:N NT Link by mounting 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
NT31/NT31C with the high-speed 1:N NT Link through RS-422A/RS-485.

Set any value between 0000 and 0009 hex for the baud rate. The same
baud rate will be used regardless of the value as long as it is between 0000
and 0009 hex.
