Things You May Know About HART n n Most smart instruments use HART Communication HART smart field devices are used interchangeably with traditional 4 -20 m. A analog only units Hand Held Communicators are often used to perform device set-up, calibration, commissioning and periodic maintenance functions PC-based instrument management tools can remotely communicate with HART devices to manage calibration and other instrument parameters from central locations (instrument shop or control room) HART = Savings in Installation & Maintenance HART is a registered trademark of the HART Communication Foundation 2

Things You May Not Know About HART n n n All HART smart devices provide process data for plant operation continuously - 24/7 HART provides access to all device data while the 4 -20 m. A analog signal is being used for control Information about the status (health) of the field device and quality of the 420 m. A signal is part of every message The Primary Variable is transmitted as a 4 -20 m. A signal and also as digital value Many devices have process information (measured or calculated) in addition to the Primary Variable This Data is VALUABLE $$$ HART is a registered trademark of the HART Communication Foundation 3

HART Basics 4 -20 m. A Digital FSK allows additional information to be carried on the same pair of wires with the 4 -20 m. A Analog Signal Simultaneously and Transparently HART is a registered trademark of the HART Communication Foundation 4

The HART FSK Signal The Familiarity of 4 -20 m. A… with the Benefits of Digital Communication HART is a registered trademark of the HART Communication Foundation 5

Valuable Data _ 35 -40 data items are Standard in every HART device _ Device Information Basic Calibration Information Process Variables Diagnostic Status Alerts Use this Data to Improve Process Operations and Better Manage Plant Assets All Data is easily available to Plant Systems! HART is a registered trademark of the HART Communication Foundation 6

Digital Process Variables _ Many HART devices support more than one process measurement or calculated value _ HART provides access to All Process Variables in the device _ All Digital Process Variable data includes: _ IEEE Floating Point Value Standard Engineering Units Code Data Quality Status Primary Variable transmitted on the 4 -20 m. A current loop continuously HART is a registered trademark of the HART Communication Foundation 7

Status & Diagnostic Alerts _ _ All HART smart field devices continuously self-assess and monitor their performance Diagnostic status information is returned with every message Status Alerts include quality of 4 -20 m. A signal and process variable data Continuous communication increases integrity of control system information Get early warning of device problems Automatically track and detect changes in Range or Engineering Units Validate PV and Loop Current values at control system with data from the source field device HART is a registered trademark of the HART Communication Foundation 8

Example Applications n n n Is the p. H electrode cracked or coated? Has the temperature sensor failed? Is the measurement accurate? Is the measurement within range? Are the impulse lines clogged? Has the pressure sensor been over-ranged? Has the device been left in “loop test” position? Is the air pressure adequate to operate the valve? Is the control valve operating smoothly over the full range? Has the device failed or locked-up? Will the Emergency Shut Down valve operate if required?
