Fieldbus Foundation announces first H1 ITK 6.0 registered devices
20 December 2011
The Fieldbus Foundation has announced that it has registered the first FOUNDATION fieldbus devices based on its H1 Interoperability Test Kit (ITK) Version 6.0.
Fieldbus Foundation has announced that it has registered the first FOUNDATION fieldbus devices based on its H1 Interoperability Test Kit (ITK) Version 6.0.
Supplied by Emerson Process Management and Yokogawa supplied the registered H1 (31.25 kbit/sec) devices were tested for functionality and conformity with the FOUNDATION function block and transducer block specifications.
Emerson’s registered devices include the TopWorx D2-FF discrete valve controller, which combines analogue/digital position sensing and monitoring with FOUNDATION fieldbus communications and pilot valve output drivers for on/off applications; and the Rosemount Analytical 1066 pH transmitter, which measures pH and ORP/Redox, and provides sensor, transmitter, and calibration diagnostics to the bus via field diagnostics.
Yokogawa’s registered devices are enhanced pressure transmitters featuring innovations in multi-sensing technology that make optimal use of the characteristics of a single-crystal silicon resonant sensor. They also support AR, IS, SC, IT and PID function blocks; NE107 field diagnostics; and software download function.
All H1 ITK 6.0 tested devices support the latest advances in field diagnostics per the NAMUR NE107 recommendation, which build upon the existing diagnostic capabilities of FOUNDATION fieldbus equipment, and at the same time, add a greater degree of organisation so field instruments can represent their diagnostics in a more consistent way.
Employing NE 107 field diagnostics capabilities, for example, allows non-critical diagnostics to 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. This and other advanced ITK 6.0 features are fully configurable to provide utmost flexibility in user applications.
