Hart protocol

If you have 4-20mA process instrumentation, you probably have. But some new in the automation field may need a refresher on this powerful technology. This course gives a brief . A two-way or bidirectional communication protocol , which addresses this drawback, has been developed with which additional information can be transmitted using an alternating current signal superimposed on the – 20mA analog signal.

No other field communication technology comes close—in size or scope of installation and overall effectiveness.

Field instrumentation in process plants is beginning to come under more sophisticated metrological discipline. Most new field instruments are now smart digital instruments. HART Communication Protocol. With over milliondevices installed it is the most popular protocol used in the field. HART” is an acronym for Highway Addressable Remote Transducer.

The blog post was co-authored by Audrey Dearien. Communications in industrial automation systems enable the transfer of data, commands and other information to streamline process control and factory automation.
