INTRODUCTION
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 4-20mA in proportion to the process variable being represented. In typical applications a signal of 4mA will correspond to the lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%) of the calibrated range. If the system is calibrated for 0-100 PSI, then an analog current signal of 1 ....etc

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 communic ....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? ....etc

scope and limitations of student information system

A student information system (SIS), student management system, school administration software or student administration system is a management information system for education establishments to manage student data. Student Information Systems (often abbreviated as SIS systems) provide capabilities for registering students on courses, documenting grading transcripts and results of student test and other assessment scores, build student schedules, track student attendance, and manage many other ....etc

What is HART?
(Highway Addressable Remote Transducer)
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.
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 commu ....etc

Little more than a decade ago, online job searches were primarily the province of a tiny population of hardcore techies. Today, online recruiting forms one of the central pillars of a smart staffing strategy for firms in every economic sector.

Increasingly, job seekers are turning to electronic resources such as corporate web sites, federal, state, and municipal job postings, online job search engines and aggregators, Internet classifieds, and online versions of local and national newspapers to facilitate the job search process. Conversely, ....etc
