Overview


The HART Communications Protocol (Highway Addressable Remote Transducer Protocol) is a bi-directional industrial field communication protocol used to communicate between intelligent field instruments and host systems.

This example program demonstrates communication with HART primary devices using a RS-232 to HART modem.

During development the code was used with a MicroLink HART Protocol Modem (http://www.microflx.com/Microlink.htm) and tested with a Emerson Rosemount 1151 Pressure Transmitter.

You can connect up to 15 sensors to each RS-232 port using the MicroLink modem. It is compatible with devices conforming to HART version 5.
