Standardised nearly 30 years ago, HART (Highway Addressable Remote Transducer) is the most broadly supported protocol in the world for the process industry
HART was originally developed as a way to make analogue process measurement devices “smarter” by superimposing digital data on a 4…20mA signal loop.
The standard continues to develop
Today, more methods of connecting are regularly being introduced – including wireless and Ethernet. Backwards compatibility and manufacturer interoperability means you face no danger of getting locked into vendor-specific or regional solutions.
Phoenix Contact has developed the PL GW…-BUS modular gateway system which provides a simple way to parameterise and monitor HART devices via HART-IP, Profinet, Modbus TCP, and FDT/DTM for easy integration into nearly any host system. It is a modern alternative for traditional RS485 HART multiplexers.
To facilitate easier installation on existing sites Phoenix Contact has developed the Wireless Hart Gateway and Adaptor
RAD-WHG/WLAN-XD WirelessHART gateway
A DIN rail-mounted gateway that provides a simple way to access HART devices for configuration, calibration, and monitoring via HART-IP, Modbus TCP, or FDT/DTM.
In conjunction with the standard Ethernet interface, the gateway also features an integrated 802.11b/g transceiver for backhaul, mobile operator, or HMI connection.
RAD-WHA-1/2 NPT WirelessHART adapter
This rugged field-mount device is ideal for connecting up to four HART devices. The adapter may be loop or 24 V DC powered, and can be retrofitted to an existing installation while maintaining the analogue control system, without reworking marshalling cabinets.
