If you use HART instruments in your facility but do not have a plant-wide HART monitoring system, you may not realize how much important HART information you can actually collect and may be missing! The Extracting HART Data From Smart Instruments white paper discusses how you can use HART interface devices to easily acquire HART data and even send it to PLC or DCS controllers or monitoring systems. These HART interfaces can also help automate your partial stroke testing (PST) with Emergency Shutdown (ESD) valves that are part of your safety system.
According to the Fieldcomm Group (formerly the HART®Communications Foundation), there are more than 30 million HART-enabled instruments installed in chemical and process plants worldwide. These instruments superimpose a digital (HART) signal onto their 4-20mA process signal that contains additional process measurements and other variables that usually include device status, diagnostic data, alarms, calibration values and alert messages.
In many cases, HART instruments were installed in a plant solely because they could be easily configured and diagnosed with a HART Handheld Communicator (HHC). However, for a number of reasons, including the prohibitive cost of installing a plant-wide HART monitoring system or lack of familiarity with alternatives, existing diagnostic and process variable data goes unused.
