I have not read through the entire thread, so I am unsure as to if someone has already suggested this, but how about using a simple IP to MSTP router (ie Contemporary Controls) and then an open source software such as Mango M2M? I use Mango M2M and have been very impressed with it, though one could always wish for more.
Modbus RTU/TCP Niagara AX driver available from Infocon can discover Modbus Device ID. But not points.. However, this will ease the Engineer at site to know the device is online with the Baudrate, Parity and bits set correctly. both TCP and RTU in a driver at a fraction of cost. A bit late but you can answer Intsys now and get back some beers! Cheers..!
