Introduction
The HART
many 4 ... 20 mA transmitters to enable digital communication for diagnosis and maintenance
purposes. Many device parameters, but also measurement values, can be transmitted digitally
to and from the device. Until now, HART
4 ... 20 mA loop as physical layer.
WirelessHART
employable worldwide, WirelessHART
wireless network) as physical layer. All WirelessHART devices form a mesh network in which
every device is not just a measurement point, but also a repeater. This results in a bigger range
of the whole network as well as an increased reliability through redundant communication
paths.

Host applications
The WirelessHART network is built up, organized and maintained by the WirelessHART
Gateway and is therefore self-organizing and self-healing. The WirelessHART Gateway also
takes care for connection to different host systems through different industrial protocol bus
interfaces.
The WirelessHART Gateway supplies WirelessHART Temperature Converters and
WirelessHART Adapters with the necessary information for seamless network operation.
