When using a CPM1
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 of a C200HX/HG/HE(-Z)E, CQM1 or 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 area (data memory) effective.
