4-3  High-speed 1:N NT Link 
• Supported Host Units  
The OMRON PLCs that can be connected to high-speed 1:N NT Links using RS-232C are as 
follows: 
CS-series PLCs: CS1G/H-V1 and CS1G/H-H  
CJ-series PLCs: CJ1G, CJ1G/H-H, and CJ1M 
 
CS-series PLCs can also be connected in high-speed 1:N NT Links by using a CS1W-SCU21 
Serial Communications Unit or CS1W-SCB21/41 Serial Communications Board. (CS-series 
PLCs without a -V1 suffix can also be connected in high-speed 1:N NT Links if a Serial Com-
munications Unit is used.) CJ-series PLCs can also be connected in high-speed 1:N NT Links 
by using a CJ1W-SCU41 Serial Communications Unit. 
The OMRON PLCs that can be connected in high-speed 1:N NT Links using RS-422A are as 
follows: 
CS-series PLCs: CS1G/H and CS1G/H-H 
CJ-series PLCs: CJ1G/H-H, CJ1G, and CJ1M 
 
CS-series PLCs can also be connected in high-speed 1:N NT Links by using a CS1W-SCB41 
Serial Communications Board. (CS-series PLCs without -V1 suffix can also be connected in 
high-speed 1:N NT Links if a Serial Communications Board is used.) CJ-series PLCs can 
also be connected in high-speed 1:N NT Links by using a CJ1W-SCU41 Serial Communica-
tions Unit. 
Check the series and model of the PLC and the model of the Board or Unit that are mounted 
to the PLC when connecting the PT to the host. For details on the PLCs that can be con-
nected, refer to Appendix 8 Standard Models.
