WirelessHART is the first open wireless protocol certified for industrial applications, providing backward compatibility with HART technology. It features a mesh network topology with secure data link layers and utilizes a multi-vendor support system for process monitoring and control. The protocol offers cost savings, easy installation, and improved access to information in hard-to-reach areas.
WirelessHART
- 2. What is? WirelessHART is the first open wireless protocol to be certified for industrial applications. WirelessHART provides a backward compatibility with the widely used HART technology.
- 3. WirelessHART Evolution HART Evolution (HCF) 2010 IEC 62591 2014 Chinese National Standard GB/T 29910.1-6-2013

Reliable strem transport. Negotiated Segment sizes Network Power-Optimized. Redundant Path. Mesh Network Data Link Secure. Time Synched TDMA/CSMA, Frequency Agile with ARQ Physical IEEE 802.15.4 based radios. Up to 10dBm Tx Power. 2.4GHz Wireless
- 5. WirelessHART Network Infraestructure •Modbus •Ethernet •485 interface •OPC
- 6. WirelessHART Main Features Mesh Topology - Routers - Spatial diversity
- 7. WirelessHART Main Features Channel hopping - Frequency diversity - Only nodes in the network know next channel
- 8. WirelessHART Main Features Acknowledgment - Synchronous operation Non broadcast messages have ACK which also is use as a sync mechanism among the nodes in the network.
- 9. WirelessHART It is a simple, reliable and secure protocol! Built on proven industry standards Created by industry and technology experts Multi-vendor support and interoperable devices Uses existing devices, tools and knowledge Process monitoring, control and asset management Health, safety and environmental compliance monitoring
