I am migrating an Allen-Bradley SLC based system to ControlLogix and need some help with DeviceNet addressing. The SLC system has a 1747-SDN and I am using a 1756-DNB in the new system. The system only has digital I/O on DeviceNet. In the SLC system the 1747-SDN module is mounted in slot 11 so the addressing simply uses O0:11 for the output data table and I1:11 for the input data table. There are no analog I/O. I am not able to scan the DeviceNet network at this point. (It is at a customer location) Is there a way to set up the addressing ahead of time. Do I need to know the part numbers of the specific devices being used? I do know they are selector switches for the inputs and pilot lights and solenoids for the outputs. Any advice would be appreciated.
