Hart general information l.jpg
HART – General Information

  • HART (Highway Addressable Remote Transducer)

  • MSA device is a slave in a polled network

  • HART is a software protocol running over 4-20mA Hardware

  • Point to point

  • 1200 baud FSK

Hart general information con t l.jpg
HART – General Information con’t

  • HART Communication is a bi-directional industrial field communication protocol used to communicate between intelligent field instruments and host systems.

  • HART provides two simultaneous communication channels: the 4-20mA analog signal and a digital signal. The 4-20mA signal communicates the primary measured value (in the case of a field instrument) using the 4-20mA current loop - the fastest and most reliable industry standard. Additional device information is communicated using a digital signal that is superimposed on the analog signal. The digital signal contains information from the device including device status, diagnostics, additional measured or calculated values, etc. Together, the two communication channels provide a complete field communication solution that is easy to use and configure, is low-cost and is very robust.

Sales support l.jpg
Sales Support

  • Customer requirements

    • HART handheld controller

      • Must be compatible with the Emerson 375

      • Emerson 275 will NOT work

      • HART Rev 6 or Rev 7

    • Latest DD’s downloaded to handheld controller

      • A Device Description (DD) is an electronic data file prepared in accordance with Device Description Language specifications that describes specific features and functions of a device including details of menus and graphic display features to be used by host applications (including handheld devices) to access all parameters and data in the corresponding device.

      • Download from Emerson website (or other handheld controller that subscribes to the HART foundation updates)

      • Through HART membership www.hartcomm2.org

      • Available from MSA
