Research on Profibus and Redundant Profibus-based Supervisory System
Fieldbus is the focus in automatic supervisoryfield, and it stands for the technology orientation. Profibus has many technological advantages, so it is of great importance for protective engineering to study Profibus. At first, the technology characteristics of Profibus are described briefly. On the ground of high reliabilities demanded by protective engineering, a redundant supervisory system based on Profibus is designed. Then the reliability difference is discussed compared with the module-level redundant system. Also a redundant Profibus slave station′s implementation is presented. Finally the article gives the experiment results, which verify that the given redundant system structure is feasible, and the designed redundant slave station has satisfatory performance.
