Connecting to CPM2C PLCs
The CPM2C has a single connector that is the same shape as a CS-series peripheral port.
Internally, the connector has signal lines that are for use with the CPU's built-in RS-232C port
and the peripheral port. Therefore, when using the CPM2C, use the settings for the CPU's
built-in RS-232C port or for the peripheral port according to the converter cable and port
used, as follows: Refer to the CPM2C Operation Manual (W356) for details.
CS1W-CN118 port (D-Sub 9-pin)
