Offerings for

HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation protocol which is the most widely used communication protocol in the Process Automation Industries. HART communication protocol is maintained by HART Communication Foundation (HCF) earlier now by FieldComm Group (

Utthunga has good experience and expertise in various flavors of HART communication protocols like HART RS 485, Bell-202, HART-IP, wirelessHART and HART MUX.

HART 7 Stack

We offer a ready to use HART 7 communication protocol stack conforming to the protocol that enables faster firmware development of HART-enabled field devices. We offer integration and porting of the stack with the target device application and device platform. This includes:

  • Porting of the stack library to device hardware platforms including micro-controllers and RTOS
  • Integration of the stack library with the device application software or firmware
  • Enhancements to the stack library to support the device family as well as device-specific commands

OPC Solutions

Utthunga’s proprietary framework DPI (Device Programming Interface) with common source base for desktop and mobile (Android and iOS) has been used in developing various Dashboard application, diagnostic and service tools to monitor, parameterize the various instruments using HART Serial (RS 485, Bell 202), HART-IP and HART MUX.

handheld Configurator

Utthunga can develop HART EDDL based solution using DD interpreters like SDC 625 or EDDEngine for handheld Configurator applications.


Utthunga can provide all Device Integration Standard support for HART protocol like HART DD development and registration or HART Device DTM Development, HART-IP Gateway DTM Development or FDI HART Device or Profile package development. Utthunga can also develop HART FDI Communication Server for your FDI host.

HART board and stack

Utthunga can help you to make your legacy 4-20 mA device to be digital by making it HART compatible using retrofit Utthunga’s HART board and stack.

HART Simulator

Utthunga can develop the HART Simulator (H/W and S/W) which can be used to perform load test the Control system by simulating thousands of HART devices.

Mobile-based Dashboard

Utthunga can develop the mobile dashboard application for Android and iOS using its proprietary HART-IP stack and DPI framework which can communicate with HART devices over a network.
