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

STREET LIGHT POWER CABLE MONITORING SYSTEM BASED ON WIRELESS SENSOR NETWORKS USING ZIGBEE COMMUNICATION
Abstract:
In the real time applications Turnoff the street lights on time is a problem where human memory involves. To overcome this problem we use wireless device to monitor the parameters which do the task automatically with predefined time. The fundamental aim of this project is to develop an embedded system to design a ....etc

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

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

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?

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
