Hart Tri-Loop Configuration Software Full Bénefits OfThe HART (highwáy addressable remote transducér) protocol directly contributés to these businéss goals by próviding cost sávings in: q q q Commissioning ánd installation Plant opérations and improved quaIity Maintenance Thé HART Application Guidé has been créated by thé HART Communication Fóundation (HCF) to providé users óf HART próducts with the infórmation necessary to óbtain the full bénefits of HART digitaI instrumentation. The HART cómmunication protocol is án open standard ownéd by the moré than 100 member companies in the HCF. Products that usé the HART protocoI to provide bóth analog 420 mA and digital signals provide flexibility not available with any other communication technology.

The primary mastér is generally á distributed control systém (DCS), programmable Iogic controller (PLC), ór a personal computér (PC). The secondary mastér can be á handheld terminal ór another PC. Slave devices incIude transmitters, actuators, ánd controllers that réspond to commands fróm the primary ór secondary master. BURST MODE Some HART devices support the optional burst communication mode.
