    HART protocol (Highway Addressable Remote Transducer) is a widely used communications protocol, amongst all the industrial automation protocols.

    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 build, test, certify and deploy HART enabled products in the market.
