HART Introduction| 6/17/15

HART IntroductionHART (Highway Addressable Remote Transducer) :
The HART protocol was developed in the mid-1980s by Rosemount Inc.
for use with smart measuring instruments. The registered trademark and all
rights in the protocol were transferred to the HART Communication
Foundation (HCF). The protocol remains open and free for all to use without
royalties.
Features：
 Communicates at 1200 bps.
 Support 4-20mA analog signal (primary measured value) and
digital signal (device information).
 Support point-to-point or multi-drop network. (Max. 15 devices)
 Support 2 wire (Bus Powered) or 4 wire (device ).
 HART is a master/slave protocol (up to two masters).
 HART Instrument with intrinsically safe explosion-proof.
