Remote Control of COM Ports of the CM574-RS Communication Module

Note

In order to use remote COM protocols for a CM574-RS serial port, the corresponding COM must be set to COMx- Shared within the CM574-RS CPU project.

CM574-RS Communication Module’s COM ports can be configured and used directly in the CPU project as if they were local COM interfaces. Each communication channel can be replaced by a COM port which is linked as follows:

• Channel 1 –> COM1 on CM574-RS Communication Module
• Channel 2 –> COM2 on CM574-RS Communication Module

The following protocols are available:

• ASCII
• M
• CS31-Bus

The protocol selection as well as the configuration of the available parameters is done in the same way as it is known for a local COM interface. See Setting Up the Protocol of a Serial Interface Setting Up the Protocol of a Serial Interface.
