I have problem about DeviceNET configuration at ABB S4C+. I can't create new I/O unit type or change among existing unit as a default. I need to create communication with S4C+ and Beckoff deviceNET bus coupler. I created I/O unit but I need a I/O unit type which inculude Beckoff "vendorid, product type etc.". How can I create a new I/O unit type?
