Connecting to the RS-232C Port at the Host Section 4-1
The following table shows which CS-series PLCs can be connected to an
NT31/NT31C with the high-speed 1:N NT Link.
*1
The high-speed 1:N NT Link is not supported for a direct connection to the
CPU Unit of a CS-series CPU Unit without the -V1 suffix.
*2
A CS1W-SCB21 or CS1W-SCB41(-V1) Serial Communications Board or
CS1W-SCU21(-V1) Serial Communications Unit is required.
*3
A CS1W-SCU21(-V1) Serial Communications Unit is required. A CS1W-
SCB21/41(-V1) Serial Communications Board cannot be used.
*4
One of the following Communications Units is required:
CJ1W-SCU21/41(-V1)
Settings at the Host
The Settings required for each Unit are described below.
■ Connecting CS/CJ-series CPU Units
CS/CJ-series CPU Unit: CS1G/H-CPU@@-EV1, CS1G/H/D-CPU@@H,
CJ1G/M-CPU@@, CJ1G/H-CPU@@H
Connect to the built-in RS-232C port on the CPU Unit. A special Peripheral
Port Connecting Cable (CS1W-CN118) can be used to connect to the periph-
eral port.
PLC Setup
When connecting to a CS/CJ-series CPU Unit, set the following communica-
tions conditions for the PLC Setup area, in accordance with the communica-
tions port to be used.
Using the CPU Unit’s Built-in RS-232C Port
Using the CPU Unit’s Peripheral Port
