WirelessHART Wins International Approval

With the National Committees of 29 countries participating in the balloting, the International Electrotechnical Commission has approved the WirelessHART Communication Specification (HART 7.1) as a Publicly Available Specification (IEC/PAS 62591Ed. 1). The industrial wireless communication technology is backward compatible with existing instrumentation and host systems, preserving users’ investments in previous Hart technology.

Released by the HART Communication Foundation (HCF) in September 2007, WirelessHART Communication is the first open and interoperable wireless communication standard designed to address the critical needs of the process industry for reliable, robust, and secure wireless communication in real-world industrial plant applications. The standard builds on established and field-proven international standards including the HART Protocol (IEC 61158), EDDL (IEC 61804-3), IEEE 802.15.4 radio and frequency hopping, spread spectrum, and mesh networking technologies.
