USERS' GROUP FORMED TO PROMOTE SMART FIELD INSTRUMENTATION PROTOCOL

Eighteen companies have formed the HART (Highway Addressable Remote Transducer) Users Group. HART, which was introduced by Rosemount Inc. in 1986, allows digital signal communication between a control room and field devices, such as transmitters.

The group was formed in response to a growing global interest in smart field instrumentation protocol. The group's aim is to promote the use of a protocol, to maintain interchangeability among similar or other HART-based devices regardless of vendor, and to ensure that future changes to the HART protocol are consistent with the goal of interchangeability and interoperability.

The member companies include: Applied System Technologies Inc., Asea Brown Boveri Ltd., Camille Bauer Inc., Delft Instruments Tank Gauging B.Y., Eckardt AG, Fischer & Porter Co., and Fisher Controls International Inc. Also included are: Flowtec AG, Hitachi Ltd., Measurement Technology Ltd., NovaTech Inc., Procter & Gamble Co., Rosemount, Schoppe & Faeser GmbH, Smar International Corp., Toshiba Corp., Valtek Inc., and Yokogawa Electric Corp.

Many of the group's members are also active in the formulation of a fieldbus standard and believe there is also a need for a common protocol providing simultaneous analog and digital communications. Membership in the HART Users Group is open to any company.
