Modbus with Digi Transport WR


I’m working on implementing a Modbus application that would read sensor data from a PLC, using Python on a Digi gateway. I browsed the forums a bit and found Lynn’s excellent contribution to integrate Modbus with python using the IA Modbus Engine.

My question is, I would like to use the Digi Transport WR21 for this purpose, but according to the wiki pages that is not possible, am I right? The WR21 specs says it supports Modbus over UDP/TCP though. Is there any way this could be implemented on a Transport WR21 using existing Modbus Client code or would it require to build everything from scratch?
