Fieldbus is Dead, Long Live Fieldbus!

Our End User Advisory Council chairman John Rezabek has written a great column in Control about the recent spate of articles and research reports that talk about Ethernet and fieldbus.  First, let me say that we at the Fieldbus Foundation couldn’t agree more about Ethernet.  We knew Ethernet would be widely accepted as an industrial networking technology many years ago when we adopted Ethernet and standard IP for our HSE network.  However, many issues still remain regarding Ethernet deployment at the field device level,  many of which are discussed by John in this article. There’s a difference between Ethernet and fieldbus, and the two aren’t mutually exclusive.
