Startup of the World’s First Commercial Fieldbus System

April 15th, 1997, Fort Saskatchewan, Alberta, Canada

Installation and Commissioning of ninety six(96) 3051T transmitter was completed in 5 hours by 3 instrument tech’s.

Project Savings of over 30% have been documented by customer for the fieldbus installation vs traditional installation.


Detailed View of DeltaV Controller Field Enclosure

Redundant power supplied to each segment.

DeltaV fieldbus modules interfaced to each fieldbus segment

Redundant Ethernet connection provided to field hub.


Quick disconnects used at the transmitter to speed installation and to allow transmitters to be easily added and removed from the fieldbus segment.

Sixteen 3051T transmitters per fieldbus segment, 6 segments installed for a total of 96 transmitters
