4-2 1:N Host Connection
@ 1:N NT Links
This section describes the methods used to connect multiple PTs to a single host in a 1:N
connection and provides information on the relationship between the connection methods and
the communications methods.
• The Host and PTs are connected in a 1:N configuration using RS-422A with an RS-
232C/RS-422A Converter. (Refer to page 4-9.)
This connection method can be used for 1:N NT Link connections (normal, high-speed).
PT
Both serial ports A and B cannot be used, however, to connect to PLCs in a 1:N configuration
at the same time.
• Supported Host Units
OMRON PLCs that can be connected in 1:N NT Links are limited to CS/CJ-series CS1G/H,
CS1G/H-H, CJ1G/H-H, and CJ1G, C-series C200HX/HG/HE (-Z), and CQM1H (when using
CQM1H-SCB41 only). The CS-series can also be connected in 1:N NT Links by using a
CS1W-SCU21 Serial Communications Unit. The CJ-series can also be connected in 1:N NT
Links by using a CJ1W-SCU41 Serial Communications Unit.
Check the series and type of the PLC and the model of the Board or Unit that is mounted to
the PLC when connecting the PTs to the host.
