One of the following Communications Boards is required:
C200HW-COM02/COM04/COM05/COM06-E(V1)
*5
A CQM1H-SCB41 Serial Communications Board is required.
Reference: With version 1 (-V1) and high-speed versions (H) of the CS-series CPU Units
and any versions of the CJ-series CPU Units, the high-speed 1:N NT Link
method can be used as well as the standard 1:N NT Link method. Furthermore,
the high-speed 1:N NT Link can be used in earlier versions of CS-series CPU
Units (pre-version-1 and non-high-speed) by installing a new version of a Serial
Communications Board or Unit. For details, refer to Using the High-speed NT
Link (1:N) Method (page 69).
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. SYSMAC support software) in accordance with the host
model and port.

RS-232C port on the Communications Board
*2
RS-232C port on the Serial Communications Board
*3
When using a C200HE (-Z)E, the maximum PT unit number is 3.
Refer to the PLC’s operation manual for details on changing PLC Setup set-
tings.
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.
Connecting to CS/CJ-series CPU Units
CS/CJ-series CPU Unit: CS1G/H-CPU@@-E(V1), CS1G/H/D-CPU@@H-E,
CJ1G/M-CPU@@, CJ1G/H-CPU@@H
The PT is connected to the built-in RS-232C port on the CPU Unit. It can also
be connected to the peripheral port on the CPU Unit, but a CS1W-CN118
Peripheral Port Connecting Cable must be used.
