* In case of K7M-DR10UE (/DC) and K7M-DR14UE (/DC), you are not able to use built-in RS-232C/485 at the same time.

When you want to use built-in Cnet, you have to select either built-in RS-232C (Cnet dip switch on) or built-in RS-485 (Cnet dip switch off). In these two types, if you are going to use Cnet I/F module, you cannot use any built-in Cnet channels while built-in Cnet dip switch is on.

* In other economic types, you are not supposed to use built-in RS-232C and Cnet I/F module at the same time. When you turn off Cnet dip switch, you can use Cnet I/F module.
