Using the 1:N NT Link Compatible Host Units
The OMRON PLCs that can be connected using the 1:N NT Link are the CS-
series (CS1G/H or CS1G/H-H), CJ-series CJ1G, C-series C200HX/HG/HE(-
Z)E, CQM1H, and SRM1 only. With the CS/CJ-series PLCs, it is possible to
connect a 1:N NT Link using a CS1W-SCU21 or CJ1W-SCU41 Serial Com-
munications Unit.
Check the model and series of the PLC as well as the model of Serial Com-
munications Board or Unit being used before making the connections.
The hosts that can be connected to the NT20 by the 1:N NT Link using the
RS-232C ports of both Units are indicated in the table below.
