Connecting to a CPM2C
The CPM2C PLCs do not have the same kind of port connectors found on CS-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 connections, 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.
