Abstract

The research on Profibus-based decentralized supervisory control apparatus of hydropower plants is a new task based on the research on MB series PLC,using fieldbus and embedment technologies.The architecture of the new type of supervisory control apparatus and the communicating mechanism of the Profibus-DP are introduced.The design of the Profibus-DP master is discussed in detail.The application of Profibus and embedment technologies according with the international standards improve the openness,real-timeness and reliability of the system.
