  1. WirelessHARTTM Expanding the Possibilities Wally Pratt HART Communication Foundation Austin, Texas USA

  2. About HART Communication Foundation • Founded in 1993 – International, not-for-profit organization • Supported by 200+ global companies – all the majors, plus many with unique products • Exist for benefit of industry – provide worldwide support for application of the HART technology • Manage and Control the HART technology and standards • Full time staff with technical/support specialists in 3 offices – USA, Europe, China, others in future • Test programs, tools and registration services to confirm compliance of product implementations • Training workshops, trade show exhibits, website, newsletter and other programs to educate industry on HART Communication • Develop new technology and enhancements to support industry needs

  3. About HART Communication • Leading communication technology for smart process measurement and modulating control devices • Global standard used in process applications around the world • An international standard – IEC 61158 • Large international support and installed base • Traditional use has been with hand-held tools to set-up, configure and troubleshoot smart devices • New DCS systems use HART for continuous monitoring and integration of advanced diagnostic and multi-variable capabilities of smart devices • Wireless is a new enhancement to the HART technology with the HART 7 specifications

  4. Worldwide Installed BaseField Devices - Press, Temp, Flow, Level, Valve Positioners, Analytical ~ 56 Million Devices at Y.E. 2006 Source - ARC Advisory Group, Dedham, MA Smart Non - Smart

  5. HART DA T A HART DA T A Users are Learning the Value of KeyHARTCapabilities • HART smart devices have valuable data for improving plant operation • HART devices are real-time data servers with two simultaneous communication channels • 4-20mA Analog Channel - reliable, robust, instantaneous transfer of PV control signal • HART Digital Channel - real-time device status, diagnostics, multi-variable process information • New DCS systems use both HART communication channels to access device information and validate integrity of the 4-20mA loop current DCS PAM CMMS ERP Control I/O HART Field Devices

  6. Initiative launched by HCF in November 2004 • Objective – Establish a wireless communication standard for process applications • WirelessHART • An open and interoperable standard • As easy as using wired HART • Enable wireless access to existingHART devices • Use the same configuration, maintenance, diagnostic tools and procedures • Require little additional training • WirelessHART – designed by the best minds in the industry to address the critical demands of industrial process plant applications WirelessHART

  7. Wireless Access to HART Device Information Easy Access to Intelligent Device Information Enabled by Wireless Adapter Device Status, Diagnostics, Configuration and more Major Use Case – Wireless Connection to Existing HART Devices

  8. Wireless Access to Additional Process Measurements Wireless Gateway Connection to Plant Systems Minimal Installation Cost - No Wires Battery, Solar or Field Powered Devices Enable New Class of Wireless Devices for Process Applications

  9. WirelessHART Major Enhancement to the HART Technology • New Specifications • SPEC-065 Physical Layer • SPEC-075 Data-Link Layer • SPEC-085 Network Management • SPEC-155 Wireless Commands • SPEC-290 Wireless Devices • Enhanced Universal Commands • Time Stamps, 16 Bit Manufacturer IDs • 27 New Common Practice Commands • Enhanced Burst Mode, Automatic Event Notifications, Measurement Trending, Command Aggregation • WirelessHART User Manual "WirelessHART entails much more than simply adding a radio to HART field devices. It enhances HART functionality, and preserves the viability of HART's future indefinitely."-Wil Chin, ARC Advisory Group, Research Director Automation

  10. Multi-Company DevelopmentUsing Standard HART Practices • Technology Development Process • Started with Proposal – Nov 2004 • Call for member participation • Formed Technical Working Group • Started with Use Cases & Requirements • User Needs & Backward Compatibility - the Top Priority always! • WG decided key concepts – many meetings + diligent effort, consensus • Specifications written by small dedicated team of high knowledge experts • More than 25 companies involved in the developmentMajor contributions from ABB, Dust, Emerson, Honeywell, Siemens plus Endress+Hauser, MACTek, Omnex, Pepperl+Fuchs, Yokogawa and others • Draft Specifications Reviewed at multiple Meetings • Extensive Member Review & Approval period with formal Ballot Following Member Approval and Ratification by the Board of Directors – the Approved HART Specifications are openly available

  11. Self Organizing & Self Healing Wireless Mesh Network • Reliable - Messages routed around interference, obstacles • Simple - Same wireless capabilities for all field devices • Flexible - User chooses topology, speed, application • Preserves the HART User Experience – Same tools and practices as wired HART • HART Command structure - Compatible with HART-enabled control systems and EDDL • Robust Security - Uses industry-standard AES-128 ciphers & keys • IEEE802.15.4 Radio at 2.4GHz - Frequency hopping for reliability and coexistence WirelessHART:Secure, reliable wireless communication for process measurement and control applications

  12. WirelessHART Devices • Total Solution • Wireless Field Devices • WirelessHART Adapters • Gateway / Access Points • Network Manager • Wireless Handhelds • WirelessHART >> HART + Wireless • DD-enabled Application Access to all Capabilities • Smart Data Publishing and other enhancements "The HART protocol is a good match for emerging wireless mesh networks in part because it does not place heavy throughput or latency demands on the physical layer," says Harry Forbes, ARC Advisory Group Senior Analyst. "The HART Communication Foundation is doing good work that will accelerate the adoption of wireless process instrumentation."
