• Host Settings
The methods for setting each Unit are as follows:
Connecting C Series, C200HS, C200HX/HG/HE(-Z), CQM1, CPM2A, CPM2C, or
CQM1H PLCs
PLC Setup Area
Write the settings directly from the Programming Device (CX-Programmer, etc.) to the PLC
Setup Area (in DM Area) according to the host type and port used.

Refer to the manuals of the PLC being used for details on using the PLC Setup Area.
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.
Port for connecting PT PLC Setup
CS1W-CN118 port (D-Sub 9-pin) Set for built-in RS-232C.
Setting the Front Panel DIP Switch
Using RS-232C
When using C200HX/HG/HE(-Z), CQM1, or CQM1H PLCs, set the DIP switch on the front
panel to enable the PLC Setup Area (Data Memory) settings, as follows:
RS-232C port
