How does H1 fieldbus differ from the various device-level networks now in use?
H1 fieldbus was designed specifically for process automation. It differs significantly from device-level networks for factory automation in its ability to provide intrinsically safe power for field devices used in hazardous locations. Moreover, thanks to scheduling, H1 fieldbus is isochronous, which is a requirement for continuous regulatory process control. FOUNDATION H1 was designed and developed as a system technology providing significantly more structure and benefit than mere communication networks. FOUNDATION H1 technology delivers true distributed control networking; it provides asset optimization through a broad range of diagnostic capabilities and consistent data structures through the use of Electronic Device Description Language (EDDL). FOUNDATION technology also provides easy and extensive integration capabilities through open and consistent integration to HSE in a single engineering environment. Device-level networks without power and intrinsic safety, and no scheduling, a
