  1. Dear Sir,
    It was really informative topic put up in a very good manner. Explains a great deal of Grey areas as far as the HART protocol is concerned.

    I have a difficulty where in i have a field device which has HART (Active) as output and i need to read the data on DCS or a Recorder with 4-20mA as input. So kindly suggest what interface device i need to use and also state what does HART(Active) mean?
