The Research Of PROFIBUS-DP Intelligent Slave Station Technology And The Application In Detecting Oil Products

With the development of enterprise infomationization and automatization, the seamless connection between the management network and the bottom layer control network seems to be very urgent and important.Fieldbus is called as computer local network in automation domain. It is the system which is used in the manufacture field and implements the bidirectional serial multi-node digital communication among measurement and control equipments. Also, it is named as open and digital bottom control network which can implement multi-node communication. Therefore, it can be developed spreadly in automated system in many aspects.FieldBus is a new technology in development,also is one of the focuses of the current technical development in automatic field. The international electrician committee(IEC) passed the international criterion of IEC61158 in Jan 2001, which included eight types of field bus criterion,FF-Hl, ControlNet, Profibus, P-NET, FF-HSE, SwiftNet, WorldFIP and Interbus. PROFIBUS is the very important one of eight types of field bus criterion. It's the field bus of Germanic national criterion DIN19245 and European criterion EN50170. PROFIBUS-DP, PROFIBUS-FMS and PROFIBUS-PA form the series of PROFIBUS. The research on PROFIBUS-DP is the most and the application of PROFIBUS-DP is the most extensive. And it is accepted by the whole...
