    HART Stack

    Bring seamless communication within Industrial devices

  • softHART
  • Overview

    HART protocol (Highway Addressable Remote Transducer) is a widely used communication protocol in the industrial automation industry. HART is advantageous because it can communicate over the existing traditional 4-20mA signal by extending system capabilities for a two-way digital communication with ‘smart’ field instruments.


    Softdel provides a complete package that helps OEMs and ODMs speed up and simplify the process of building, testing, certifying and deploying HART-enabled products in the market.

    The ready-to-use HART protocol slave stack, compliant with revision 7.6, is available for a one-time licensing fee. The royalty-free HART stack comes with its source code and is pre-tested using HCF kit 192. The one-year warranty can be extended by selecting flexible support models after the warranty period.
