HART Command Set
A series of commands that provide uniform and consistent communication for all master and slave devices; includes universal, common practice, and device-specific commands

HART Communication Protocol
Highway Addressable Remote Transducer communication protocol; the industry standard protocol for digitally enhanced 4–20mA communication with smart field devices

HART Loop
A communication network in which the master and slave devices are HART smart or HART compatible

Host Application
A software program used by the control center to translate information received from field devices into a format that can be used by the operator

Interoperability
The ability to operate multiple devices, independent of manufacturer in the same system, without loss of functionality

Intrinsic Safety

(e.g., flammable) environments; a type of protection in which a portion of an electrical system contains only intrinsically safe equipment that is incapable of causing ignition in the surrounding environment

Intrinsic Safety Barrier
A network or device designed to limit the amount of energy available to the protected circuit in a hazardous location
