Q. What are the types of HART communicators?

Answer

A HART instrument has two types: the point-to-point mode and the multi-drop mode. When operating in point-to-point mode, only a single instrument can share a given pair of instrument cables. The HART communicator is a potent tool for establishing a two-way data link with process instruments. HART communicators, which utilize an open communications protocol, connect with HART-enabled devices through standard 4-20mA analog cabling, simplifying the process of setting up and calibrating equipment and identifying potential problems. HART communicators shine in situations when several instruments must be monitored or calibrated, or when the instruments are positioned in potentially dangerous environments.
