The Fieldbus Foundation registered the first Foundation fieldbus devices based on its H1 Interoperability Test Kit (ITK) Version 6.0, updated in October. Emerson Process Management and Yokogawa supplied the registered H1 (31.25 kbps) devices, which were tested for their functionality and conformity with the Foundation function block and transducer block specifications.
Emerson’s registered devices include the TopWorx D2-FF discrete valve controller and the Rosemount Analytical 1066 pH transmitter. Yokogawa’s registered devices are enhanced pressure transmitters.
All H1 ITK 6.0 tested devices support the latest advancements in field diagnostics per the Namur NE107 recommendation, which build upon the existing diagnostic capabilities of Foundation fieldbus equipment and add a greater degree of organization so field instruments can represent their diagnostics in a more consistent way. For example, non-critical diagnostics can be routed to a maintenance station for future work while critical diagnostics can be routed to operations with specific recommendations on how to resolve an instrumentation issue.
