  1. HART communication protocol Submitted by Manoranjankumar Branch-ETC Reg.no-0901223511

  2. INDEX • 1. Introduction • 2. How HART works • 3. Benefits of Using HART Communication • 4.Device Commissioning • 5. Device Configuration • 6. WirelessHART Overview • 7. Wireless HART - How it works • 8. Wireless HART Applications

  3. INRODUCTIONWHAT IS HART? • the HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system • HART is a bi-directional communication protocol that provides data access between intelligent field instruments and host systems • A DIGITAL UPGRADE FOR EXISTING PLANTS • A CRITICAL, DIGITAL ROLE

  4. How HART Works

  5. Two communication channel

  6. Primary and Secondary Masters

  7. Multidrop Configuration

  8. Benefits of Using HART Communication • Increase Plant Availability • Reduce Maintenance Costs • Improve regulatory compliance • Worldwide support by leading suppliers 

  9. Universal Handheld Communicators

  10. PC-Based Device Configuration and Management Tools  Connecting a PC to a HART device

  11. Backed by the Power of HART • Built on proven industry standards • Created by industry and technology experts • Multi-vendor support and interoperable devices • Uses existing devices, tools and knowledge Flexible Applications • Reduced installation costs – no wires! • Process monitoring, control and asset management • Health, safety and environmental compliance monitoring Supports All Phases of the Plant Life Cycle • Fast engineering, deployment and commissioning • Cost-effective move from scheduled to predictive maintenance • Easy diagnosing and troubleshooting

  12. WirelessHART Overview • Simple. • Easy Installation and Commissioning • Automatic Network Features • Reliable. • Standard Radio with Channel Hopping • Coexistence with Other Wireless Networks • Self-Healing Network • Secure. • Protects Valuable Information • Protects Wireless Network

  13. Wireless HART - How it works Each WirelessHART network includes three main elements: • Wireless field devices  • Gateways • A Network Manager

  15. Wireless HART Applications • Equipment and process monitoring • Environmental monitoring, energy management, regulatory compliance • Asset management, predictive maintenance, advanced diagnostics • Closed-loop control (when appropriate)

  16. From Wired to Wireless Wired or wireless, HART technology provides the tools and the flexibility you need to better manage your field measurement assets. Wired

  17. Wired + WirelessHART Adapter

  18. CONCLUSION • A Practical Digital Communication Tool for AnalogInstallations • proven successful for smart devices • proven in practice, simple design, easy to maintain and operate • simultaneous analog and digital communication • sufficient response time of approx. 500 ms • support for implementation and operation
