Fieldbus Foundation Announces First H1 ITK 6.0 Registered Devices

Emerson and Yokogawa devices support NE 107 field diagnostics

AUSTIN, Texas, December 13, 2011 – The Fieldbus Foundation today announced that it has registered the first Foundation fieldbus devices based on its H1 Interoperability Test Kit (ITK) Version 6.0.Emerson Process Management and Yokogawa supplied the registered H1 (31.25 kbit/s) 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, which combines analog/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 comprehensive 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 makes optimal use of the powerful 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 advancements in field diagnostics per the NAMUR NE107 recommendation, which build upon the existing, powerful diagnostic capabilities of Foundation fieldbus equipment, and at the same time, add a greater degree of organization so field instruments can represent their diagnostics in a more consistent way.

For example, employing NE 107 field diagnostics capabilities, 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. This and other advanced ITK 6.0 features are fully configurable to provide utmost flexibility in user applications.
