*1 One of the following Communications Boards is required: C200HW- COM02/COM04/COM05/COM06-EV1.

*2 A CPM1-CIF01 Adapter is required.

*3 Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1- CIF01 RS-232C Adapter, or CPM1-CIF11 RS-422A Adapter to connect.

*4 A CQM1H-SCB41 Serial Communications Board is required.

*5 CPU Units of CVM1/CV-series PLCs without the suffix -EV@cannot be connected.

Reference: CS/CJ-series CPU Units cannot be connected with the 1:1 connection NT link method. Use the 1:N connection NT link method (standard or high-speed) instead to make the 1:1 connection. For details, refer to Using the NT Link (1:N) Method (page 65) or Using the High-speed NT Link (1:N) Method (page 70).

Settings at the Host

The setting methods for each Unit are as follows.

Connecting to a C-series C200HS, C200HX/HG/HE(-Z)E, CPM1, CPM2A,

CPM2C, CQM1, CQM1H or SRM1 PLC

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.
