Connecting to the RS-232C Port at the Host Section 4-1
*1
Set any value between 0000 and 0009 hex for the baud rate. The same
baud rate will be used regardless of the value as long as it is between 0000
and 0009 hex.
Using the High-speed NT
Link (1:N) Method
Compatible Host Units
The high-speed 1:N NT Link method can be used with version 1 (-V1) and
high-speed versions (H) of the CS-series and CJ-series CPU Units. Further-
more, the high-speed 1:N NT Link method can be used in earlier versions of
CS-series and CJ-series CPU Units by installing the latest version of a Serial
Communications Board (CS Series only) or Serial Communications Unit.
Be sure to check the model number of the PLC and Serial Communications
Board/Unit before trying to establish the high-speed 1:N NT Link.
The following table shows which CS-series PLCs can be connected to an
NT631/NT631C with the high-speed 1:N NT Link.
*1
The high-speed 1:N NT Link is not supported in a direct connection to the
CPU Unit of a CS1-series PLC 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-E,
CJ1G/M-CPU@@-E, CJ1GH-CPU@@H-E
Connect the PT to the CPU Unit’s built-in RS-232C port. Use a CS1W-CN118
Connecting Cable, however, if connecting the PT to the peripheral port of the
CPU Unit.
PLC Setup
When connecting to a CS-series CPU Unit, set the following communications
conditions for the PLC Setup area, in accordance with the communications
port to be used.
