ABB communication with CitectSCADA via MODNET

Hi Bradley,

In order for anyone here to help you, you need to give us more details, such as how have you set up the PLC and scada (RS232/RS485, baudrate, master/slave, cable length etc) and do you get any exception response? Are they both using Modbus RTU?

The more details, the better...:)

Hi Patrick,

I managed to get comms between the two using modbus tcp/ip (MODNET). I haven't worked with ABB before so I didn't configure the ethernet port on the cpu correctly. Thanks for your response.

Regards.
Bradley.
