HART (Highway Addressable Remote Transducer) is a digital networking facility that allows any instrument, field device, or controller to be accessed for configuration and diagnostics from any point on the network. It uses frequency shift keying to send and receive data to connected devices using only two wires, without affecting the 4-20mA signal also carried by those wires. This enables centralized diagnostics and configuration of devices while retaining conventional analog signal transmission, providing the best of both digital and analog worlds.
