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 Settings
Write the PLC Setup (in the DM Area) settings directly from a Programming
Device (e.g., SYSMAC Support Software) according to the host model and
port.
Host Model
RS-232C port of C200HS, C200HX/
HG/HE(-Z)E, CPM2A, CPM2C,
CQM1, CQM1H, SRM1
Port A of C200HX/HG/HE(-Z)E (See
note 1.)
Port 1 of CQM1H (See note 2.)
Port B of C200HX/HG/HE(-Z)E (See
note 1.
CPM1
(1) RS-232C port of the Communications Board
(2) RS-232C port of the Serial Communications Board
For details on operations relating to the PLC Setup, refer to the manual for the
PLC that 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.

Setting the DIP Switches on the Front of a C200HX/HG/HE(-Z)E, CQM1,
CQM1H
When using a C200HX/HG/HE(-Z)E, CQM1, or CQM1H, the DIP switches on
the front panel must be set as shown below in order to make the settings in
the PLC Setup (data memory) effective.
