基于OPC技术的液压气动实验台监控系统设计

Design of Supervisory and Control System of Test-bed for Hydraulics and Pneumatics Based on OPC Technology

通过对液压气动综合实验台监控系统的研究与开发,介绍了OPC技术及其在液压气动实验台监控系统中的应用。详细阐述了基于OPC技术的液压气动综合实验台监控系统的设计,通过在Visual Basic6.0环境下调用OPC函数建立与OPC服务器的连接,从而实现对S7-200 PLC的数据进行读写。

Through the research and development in supervisory and control system of comprehensive test-bed for hydraulics and pneumatics, this paper introduces OPC technology and the application in the supervisory and control system, and expounds the design of supervisory and control system of comprehensive test-bed for hydraulics and pneumatics based on OPC technology. By calling the OPC functions to establish a connection with the OPC server in Visual Basic 6.0, the data from S7 -200 PLC can be read and written.
