Moore Industries Whitepaper: Extracting HART Data from Smart InstrumentsDownload Now
The “Extracting HART Data from Smart Instruments” white paper from Moore Industries details how the use of a HART interface module, such as Moore Industries’ HIM, can serve as a simple and cost-effective method for gathering HART information that can be used for monitoring instrument status, diagnostic data, alarms, calibration values and alert messages.
HART interface modules can be installed across any termination point on a 4-20 mA process loop without interfering with the analog signal to the control system and can be configured to extract or read the HART variables from the field transmitter. They “break out” these process variables from the HART digital signal, convert them to 4-20mA and discrete signals and send that data to the process control system or other receiving devices. Process variables that are commonly transmitted by HART interface modules from multivariable transmitters include mass flow, temperature, pressure, differential pressure and density or volumetric flow.
HART interface modules can also be used by engineers to monitor critical transmitters and applications. For example, a HART alarm can be set to monitor diagnostic data from a critical process transmitter when it is reconfigured or a field device malfunction occurs.
