It just worked! Oil and Gas …this wireless technology enabled us to do things we simply could not do before, either because of cost or physical wiring obstacles. Through the trials, we found that Emerson's wireless approach is flexible, easy to use, reliable, and makes a step- change reduction in installed costs." Dave Lafferty BP Brandon Robinson EnCana

32 32 © 2008 Cisco Systems, Inc. All rights reserved.C25-451582-00Cisco Confidential What is the HART protocol? (Highway Addressable Remote Transducer Protocol) Early implementation of Fieldbus. One of the most popular today. Uses 1200 baud Frequency Shift keying (FSK) based on the Bell 202 standard to superimpose digital information on the conventional 4-to- 2OmA analogue signal. Maintained by an independent organization, the HART Communication Foundation, the HART protocol is an industry standard developed to define the communications protocol between intelligent field devices and a control system. HART is the most widely used digital communication protocol in the process industries, with over eight million HART field instruments installed in over 100,000 plants worldwide. HART is supported by all of the major vendors of process field instruments HART preserves present control strategies by allowing traditional 4-to- 2OmA signals to co-exist with digital communication on existing two-wire loops.

All rights reserved.C25-451582-00Cisco Confidential WirelessHART Specification Released for Approval New technology establishes wireless communication standard for process industry applications (Austin TX USA – 17 April 2007) - The HART Communication Foundation (HCF) announces the completion of draft specifications for Wireless HART Communication and their release to HCF member companies for review and approval. Wireless HART 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 combination of HART plus wireless is a major step for the industry. Wireless HART provides new capabilities for users to get information on process parameters and to monitor the performance of plant assets in areas that have previously been technically or cost-effectively difficult to achieve, says Ron Helson, HCF Executive Director. Wireless HART ushers in the next major technology life cycle and makes possible the next generation of HART-enabled productivity solutions.
