I have several machines connected to a DH485 network. I would like to access this network via the company LAN/internet. What needs to be done to accomplish this?

I would also be interested in answers to this as well, just bought a Digi One IAP and will be playing over the next few weeks also looking at possibilty of using an OPC server and Iconics Scada

Might be something here for you:

I don't know if this is still considered the BEST solution, but RSlinx Gateway can bridge between DH485 (or whatever else) and Ethernet. Might be what you need.

Thanks for this had priced up Datalink and found in UK it would be as cheap to install 5/05 processor with ethernet built in

How about bridging through a controllogix chassis?

Look at redlion controls...datastation plus.
