Using the NT Link (1:N)
Method
Compatible Host Units
The only OMRON PLCs that can be connected using the NT link (1:N)
method are the CS/CJ-series CPU Units and the C-series C200HX/HG/HE(-
Z)E, CQM1H, and SRM1. With the CS/CJ-series PLCs, it is also possible to
connect a 1:N NT Link using a Serial Communications Board (CS Series only)
or Serial Communications Unit.
