Connecting to the RS-232C Port at the Host Section 4-1
*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 Unit cannot be connected with the 1:1 connection NT link
method. Use the 1:N connection NT link method (standard or high-speed) in-
stead to make the 1:1 connection. For details, refer to Using the NT Link (1:N)
Method (page 64) or Using the High-speed NT Link (1:N) Method (page 69).
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 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.

For details on operations relating to the PLC Setup area, refer to the manual
for the PLC which is used.
Connecting to a CPM2C
The CPM2C PLCs do not have the same kind of port connectors found on CS/
CJ-series PLCs. The CPM2C’s communications port handles both RS-232C
and peripheral port connections which are divided internally. Therefore, when
using the CPM2C, it is necessary to select RS-232C or peripheral port con-
nections, according to the kind of cable and port (on the cable) used, as
shown in the following table. Refer to the CPM2C Operation Manual for more
details.
