Profibus is mainly used in factory automation workshop level monitoring and for data communication in layer of field devices. In practical engineering applications, losing stations is the common fault in fieldbus control system ( FCS) based on Profibus technology. There are many factors may cause losing stations, the analysis found that external interferences, especially the electromagnetic interference ( EMI) and the problems in grounding system are the main factors. The factors and mechanism of losing stations are researched through Profibus network experimental platform, the reasons of losing stations are found. Combining with practical engineering application projects, relevant solutions are proposed to guarantee the stable operation of the Profibus network systems.
