WirelessHART is the intelligent further development of the proven 4 to 20 mA HART technology of the HART Communication Foundation as part of specification 7. WirelessHART is backward compatible with the cable-based HART technology and therefore offers the maximum investment security of hardware, software, tools and
experience.

WirelessHART is designed to communicate measured process variables or setpoints as well as diagnostics and
maintenance information and parameters over the network. WirelessHART uses state-of-the-art security technologies to protect the network and the data, such as meshed network topologies including
redundancy, data encryption, data integrity verification, etc.
