What is HART Protocol? Industrial Communication Explained
Overview
This video explains the HART Protocol (Highway Addressable Remote Transducer) and its role in industrial communication systems. It shows how HART combines analog (4–20 mA) signals with digital communication to allow monitoring, configuration, and diagnostics of field devices.
HART is widely used in process industries to enable communication between sensors, transmitters, and control systems like PLCs and DCS.
