HART Communication Protocol Architecture
Definition
The HART (Highway Addressable Remote Transducer) communication protocol is a hybrid analog/digital communication protocol that is widely used in industrial automation and process control applications. It supports digital communication via traditional 4-20 mA analog wire, making it compatible with existing systems while simultaneously adding new functions.
HART Communication Protocol Specifications
- It delivers digital signals over the standard 4-20 mA analog signal.
- HART lets you read and write configurations to field equipment like transmitters, valves, and sensors.
- The "Multidrop mode" lets you connect up to 15 devices to a single pair of wires.
- It allows access to device diagnostics, calibration data, and settings without interrupting operations.
- Many instrument manufacturers offer widespread support.
