Research And Development On The Profibus Fieldbus Interface

This paper is origin cf "Research and Development on the Profibus_PA Fieldbus Interface", carried on by Machinery Industry Beijing Instrument Technology and Economical Institute and supported by National Science Committee special fund. This project mainly research and develop on the technology of Profibus_PA Fieldbus interface and design an interface according to Profibus_PA protocol.Now. Profibus fieldbus is the most popular fieldbus in industry procedure controlling area. Its application area not only includes manufacturing automation, Flow_Industry automation , floor_building automation , traffic and electric power automation, but also includes food processing and chemical automation. In the world, more than hundred countries had developed a lot of varieties Profibus fieldbus products, but in China, to this day, no corporation or institute can develop and provide Profibus_PA fieldbus product by themselves. So, in our country, all of the Profibus fieldbus products in the market are imported and very expensive. Under this background, the research in my paper fills up a blank in our country in developing Profibus fieldbus products area, the research should accelerate the development in the automatically control area and reduce the different between our country and foreign country in technology.
