Choosing a controller

Hi all, I've been asked to look for a controller that can talk Foundation Fieldbus, HART and PRofibus-DP. I need to get a small DCS setup together with Remote I/O capability. This is an extention to a plant which already uses FF, HART, and PRof DP. I appreciate any help in the matter

You could try National Instruments but not sure if they do all of them. Apart from that AnyBus have a lot of protocol converters - you could also try them.

Here you Go...

Emerson Process Management's DeltaV handles all of those easily, especially the FF and HART.

Foundation Fieldbus puts you into the domain of DCS systems, where the Delta V plays.
