Omron NT631 Setting the DIP Switches of a C200HX/HG/HE-ZE, Connection to Word # Writing Setting

Connecting to the RS-232C Port at the Host Section 4-1

Reference: Version 1 (-V1) and high-speed versions (H) of the CS-series and CJ-series CPU Units support the high-speed 1:N NT Link method in addition to the standard 1:N NT Link method. Furthermore, the high-speed 1:N NT Link method can be used in earlier versions of CS-series CPU Units by installing the latest version of a Serial Communications Board or Unit. For details, refer to Using the High-speed NT Link (1:N) Method (page 70).

Settings at the Host

The Settings required for each Unit are described below.

• Connecting a C-series C200HX/HG/HE(-Z)E, CQM1H, or SRM1

PLC Setup Area Settings

Write the PLC Setup area (data memory) settings directly from a Program- ming Device (e.g. CX-Programmer) in accordance with the host model and

port.

Setting the DIP Switches of a C200HX/HG/HE(-Z)E

When using a C200HX/HG/HE(-Z)E, the DIP switches on the front panel must be set as shown below in order to make the settings in the PLC Setup area (data memory) effective.

RS-232C port communications condition setting

Set DIP SW5 to OFF to make the settings made in

PLC Setup effective.

Connecting to CS/CJ-series CPU Units

CS/CJ-series CPU Unit: CS1G/H-CPU@@-E(V1), CS1G/H/D-CPU@@H,

CJ1G/M-CPU@@, CJ1G/H-CPU@@H

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 Area Settings

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.
