Historically, the two primary technologies used for presenting and managing information from intelligent devices are FDT and EDDL. Both technologies are complimentary in some ways and overlap in other ways. Many in the industry felt that rationalizing the two technologies to form a single solution would be a good idea, particularly since all the major suppliers support both FDT and EDDL technology. This was how the Field Device Integration (FDI) project was born.
FDI activities continued, but were somewhat sporadic, until 2011, when all of the five major technology foundations, including FDT Group, HART Communication Foundation, OPC Foundation, PROFIBUS International and Fieldbus Foundation signed an agreement to form FDI Cooperation LLC, a company dedicated to seeing through the development of the FDI specification its associated development tools, and product testing and registration.
We at the Fieldbus Foundation have produced a new white paper that hopefully will take a lot of the mystery out of FDI and provide a clear explanation of what FDI is and where it is headed.
