Answer Posted / g.venkat
The majority of smart field devices installed worldwide
today are HART-enabled. But some new in the automation
field may need a refresher on this powerful technology.
Simply put, the HART (Highway Addressable Remote
Transducer) Protocol is the global standard for sending and
receiving digital information across analog wires between
smart devices and control or monitoring system.
More specifically, HART is a bi-directional communication
protocol that provides data access between intelligent
field instruments and host systems. A host can be any
software application from technician's hand-held device or
laptop to a plant's process control, asset management,
safety or other system using any control platform.
