The Development And Research Of OPC Data Access Server

OPC( Ole for Process Control) technique from an emergence suffered the favor of the personage of Industrial Process Control realm because of its advancement,but how to develop OPC application is a very complicated work.The mission that this article want to solve is how to develop the OPC application.First the article introduces the producing background, main characteristics and development condition of OPC technique, then analyzes its core COM/DCOM technique. Second the article analyzes the theories foundation and the method of design OPC application,then immediately introduces how to use ATL to design the OPC server application,and this is the core of this article. Finally the article introduces how to test OPC server application and the spot application of Fuji frequency changer OPC server application. This article still involves some other techniques, such as the usage of ForceControl software and the solution of rs485 serial communication double machine converting problem etc., among them double machine converting problem is very big bright point of this article.Zhu Yaochun (control theory and engineering) Directed by associate prof.
