Configuration of the Serial Interfaces of the CM574-RS

Note

If a COM port should be remotely controlled by the AC500 CPU project it must be set to COMx -Shared. At least an empty boot project with this setting must be deployed on the CM574-RS Communication Module.

In the standard configuration, the 2 Serial Interfaces COM1 and COM2 of the CM574-RS are pre-assigned with the Online access protocol. Thus, online access from CODESYS can occur via one of the two interfaces with the serial driver Serial (RS232) or ABB RS232 AC.

Setting up the driver is described in detail in the documentation “7.1 Programming via the Serial Interface of the CM574-RS” of CM574-RS System Technology Documentation.

To set another protocol, proceed as follows:

Right-click the respective interface and select Plug Device…

-> The Plug Device dialog appears. For more information, see section Device Dialog.

Select the desired protocol and proceed with OK button.

The protocols have the same properties as for the serial interfaces of the AC500 CPUs PM57x, PM58x and PM59x.

The current interface settings can be displayed with the PLC browser command com settings.
