HART (Highway Addressable Remote Transducer) is a Global industry standardized protocol. It communicates over existing 4-20 mA analog current loops, extending communication capabilities without the inconvenience of installing additional wiring.

Utthunga HART Slave Stack (uHSS) is a system independent stack, which can run in any environment. It is a generic stack, which can be used to develop ‘N’ number of embedded applications of HART devices. It is developed as per the global industry standard specifications provided by FieldComm Group (FCG).

uHSS is the fast way to create a field device with HART7 Features. We also provide Customized HART Stack according to your requirement.

Specifications:

  • Supports all HART7 standard Universal, Common Practice and Device specific commands.
  • Supports Request and response mode
  • Supports Burst  mode
  • Supports multi drop mode
  • Supports Single / Multi Point-to-Point communication mode
  • Supports Error detection in the received frames
  • Supports Respond to communication errors
  • Supports Extended Manufactures codes
  • Supports Private Label Code and Device Profile
  • Supports Time Stamped Data
  • Supports Expanded number of device variables in Command 9
  • Supports Upgraded Command 38 & 48 

HART IP Stack Protocol

HART IP Stack facilitates to transmit HART data over Internet protocol (IP) using Transmission Control Protocol (TCP). With this, all the HART data can be made available over IP network. It provides quick and easy way to configure, monitor and diagnose HART devices over the HART multiplexer network and WirelessHART networks from anywhere in the world with existing Ethernet network. Simply we can also call it as HART over Ethernet.

In this protocol, the actual HART message will be added with a HART IP header and TCP Header. The resultant PDU will be sent across the network. It permits the usage of Power over Ethernet (PoE) networks also. Supports several speeds like 10 Mbit/s, 100 Mbit/s, and 1 Gbit/s etc.

HART host system: Client

The HART client allows a user application to implement information exchange with a remote device. The client builds a HART request with information sent by the user application to the client interface. The request is then sent to the UDP or TCP port of the server.

HART TCP device: Server

A HART Device (server) listens for a HART request on particular port. The request is processed and a response is returned to the client that made the request.
