Fieldbus technology and rolling process automation

Fieldbus technology is the product of the development automation, computer and intelligence instruments technology. Rolling process automation is improved with development of rolling technology, control theory and fieldbus technology. It reviews the brief description of fieldbus technology. After summarizing the development of its relevant control theory, control technology and control instrument, analyzing the characters of distributed control system and fieldbus control system and considering the characters of rolling process, a new distributed control structure of rolling mill based on fieldbus is presented, and it is meet with the request of expansion, maintenance and manipulation of rolling control structure.
