Rosemount Inc. has held a leadership position in fieldbus
development for over ten years.
We've been an active participant in the SP50 Physical Layer Committee since 1985, and
we've chaired the committee from 1986-1995. We also demonstrated the world's first working
fieldbus at Interkama 1989.
Rosemount Inc. also has field experience with fieldbus. Our Hydrostatic Tank Gaging
(HTG)
system introduced in 1991 uses the fieldbus physical layer, and has systems installed
throughout the world.
Rosemount Inc. invented the HART protocol, and then dedicated the HART patents to the
public.
Similarly, Rosemount Inc. also invented the DDL (device description language), which was
used first for the HART protocol and is now used for fieldbus. We've dedicated these
technologies to the public. Rosemount Inc. was a founding member of ISPF, and we're
currently a sponsoring member of the Fieldbus Foundation.
The Emerson Process Management companies have been leading the fieldbus effort for over ten
years, and we have
spent more development dollars on fieldbus than anyone else. We plan to continue our
leadership role in this effort. As one of the largest field device manufacturers
in the world, we know that everyone wins with an open, interoperable
fieldbus.
