What is HART module?

The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.

What is HART transmitter?

Page 1. HART (highway addressable remote transducer) is the global standard for sending and receiving digital information across analog wires between smart field devices and control or monitoring systems, like PLC and DCS systems.

Is Hart protocol still used?

HART is currently the world’s most broadly supported protocol for the process industry. Almost 600 HART-based products are available from different vendors. Even hosts that aren’t designed to handle the digital information from a HART device can still have control interoperability through the 4-20 mA analog signal.

What is Hart protocol used for?

HART (Highway Addressable Remote Transducer) Protocol is an open standard used globally to send and receive digital information using analog wiring between smart devices and control systems. With over 30 million devices installed, it is the most popular protocol used in the field.

What does Hart stand for in communication protocol?

This system is called the HART communication protocol. HART stands for: Highway Addressable Remote Transducer . The HART communication protocol has become a widespread solution, allowing for convenient and efficient parameterization of smart (intelligent) measuring devices.

How is data communication done with a Hart transmitter?

For several years, the data communication was accomplished through 4-20 mA loop transmitters. The data was converted into 4-20 mA current on a two-wire loop system. The main disadvantage of this system is it can monitor only one process variable at any time. This is where HART-enabled smart devices such as HART transmitters can make a difference.

What does Hart stand for in Science category?

HART stands for: Highway Addressable Remote Transducer . The HART communication protocol has become a widespread solution, allowing for convenient and efficient parameterization of smart (intelligent) measuring devices.

Which is the primary Master of HART Communication?

HART provides for up to two masters -primary and secondary. The primary master is generally a distributed control system (DCS), a programmable logic controller (PLC), or a personal computer (PC). The secondary master can be a handheld terminal or another PC.
