Abstract:It is important to implement the produce line automation of the heat treament in steel factories for improving product quality. This paper introduces the idea of design for the delamination structure in automation system, and delaminate the system and partition the function of the system according to actual circumstances. Based on the communication mechanism of the Profibus fieldbus,this paper expatiates the communication implementation and configration of the system .
Key Words: Profibus; fieldbus; delamination structure; configration soft
