Wireless Hart

The HART
Communication Protocol has served as the world’s leading process
communication technology for smart instruments since 1989. Today, more
than 30 million HART transmitters are installed and in service
worldwide.

Industry suppliers are manufacturing and shipping HART products in
record numbers—75% of the smart transmitters installed are HART-enabled.
More HART products are installed in more plants around the world than
any other. No other communication protocol comes close.

Wireless technology allows users to access the vast amount of unused
information stranded in these installed HART smart transmitters— 85% of
the installed HART transmitters. It also provides a cost-effective,
simple and reliable way to deploy new points of measurement and control
without the wiring costs.

Simple

• Reduced installation and wiring costs
• Always on security
• Adjusts as new instruments are added and to changes in plant infrastructure

Reliable

• “Hops” across channels
• Co-existence with other wireless networks
• Optimizes bandwidth and radio time
• Mesh network and multiple access points

Secure

• Protects valuable information with multi-layered security
• Robust multi-tiered always on security
• Protects wireless network with channel hopping
• Reports message integrity failures and authentication failures
