The WirelessHART network is built up, organized and maintained by the WirelessHART
Gateway and is therefore self-organizing and self-healing. The Gateway also takes care for
connection to different host systems through different industrial protocol bus interfaces.
The WirelessHART Gateway supplies the WirelessHART field devices with the necessary
information for seamless network operation.
2.2 Functional Overview
The WirelessHART Gateway enables WirelessHART devices to communicate with each
other and manages network security and connectivity. The Gateway device converts
wireless device data to a format that is compatible with other systems.

WirelessHART (HART 7.1) specification
Interfaces: RS485 and Ethernet with support of HART communication protocol and
Modbus protocol on both interfaces
Configuration, parameterization via FDT/DTM, EDDL or Web-Interface
Fully galvanically isolated external interfaces; open-enclosure access to switches and
LEDs
Intrinsically safe antenna port (planned)
Local or Remote antenna options
Redundant supply option
Integrated web server for remote Gateway configuration and device variables
monitoring
Functionality
Measurement
•Protocols:
