HART Protocol
The HART (Highway Addressable Remote Transducer) was Developed by Rosemount Inc. as a proprietary digital Communication protocol for smart field instruments in 1986, it was made an open protocol. The HART protocol Provides backward compatible solution for smart instrument Communication as both 4- 20 mA analogue and digital Communication signals are transmitted simultaneously on the Same cable this feature made it the most widely used standard in modern instruments. HART products available now include Analogue and digital process ....etc

HART Communication

For many years, the field communication standard for process automation equipment has been a milliamp (mA) analog current signal. The milliamp current signal varies within a range of 4-2OmA in proportion to the process variable being represented. Li typical applications a signal of 4mA will correspond to the lower limit (0%) of the calibrated range and 2OmA will correspond to the upper limit (100%) of the calibrated range. Virtually all installed systems use this international standard for communicating process variable in ....etc

ABSTRACT
In the world of automation today, the DAQS (Data Acquisition Systems) manufacturers face
a great deal of problems when it comes to the compatibility with the “in-use” control network
in a particular industry. Today, there exist many control networks each one having its own
advantages and disadvantages. So it is really a big headache for the DAQS manufacturers to
decide which type of networks their systems should support and which not. Our project,
STIM (SMART TRANSDUCER INTERFACE MODULE) intends to solve this problem b ....etc

piezoelectric laminate transducer



ABSTRACT
This paper presents an energy harvester employing a cantilever beam and a magnetostrictive /piezoelectric (M E) laminate transducer to transform rotation energy into electrical energy. The harvester has a magnetic circuit attached to the free end of the beam, and the ME transducer is placed in the air gap of the magnetic circuit. When the harvester is attached to a host structure rotating around a horizon axis, the alternation of th ....etc

One of the problems of instrumentation systems is the interconnection between the multiple devices with different protocols. Minimizing the cabling cost and avoid degradation of the signal during transmission are the two typical requirements of the interconnection. Another problem in the field of manufacturing is instrumentation with different communication protocols. This seminar presents the development of a HART communication prototype for instrumentation networks. For many years, the field communication standard for process automation equip ....etc

Hi
I am Swetha,
I have some doubts regarding HART Protocol
If HART devices were connected to the asset management /process control. When device was loaded in the asset management solution, for every particular time it will send health of the device.
For how many seconds it will come?
Device Health contain how many bytes?
