Shared ports in the CM574-RS project

In any case the COM port which should be remotely controlled must be “shared” by selecting the port to COMx-Shared within the CM574-RS Communication Module project. This option automatically sets the CPU Communication Module for the corresponding communication channel to Not Used. The ability to program the CM574-RS Communication Module is not affected.

Caution

It is not possible to combine cyclic DPRAM-I/O data exchange with remote protocol functionality.
