基于C#的OPC客户端设计与应用

Design and Application of OPC Clients Based on C#

随着车间智能化程度的日益提升,车间自动化控制设备的信息采集和数据通信日益频繁.为实现自动化设备的数据采集和信息统一管理,基于OPCDA架构设计一款客户端软件,并以传送带控制单元为例验证设备通信的可行性.试验结果表明,通过OPC协议可以实现应用程序和工业控制设备之间高效、灵活的数据采集及读写任务,较好地实现了车间各类自动化设备的数据采集和信息的统一管理.

With the improvement of workshop intelligence,the information collection and data communication of workshop automation control equipment become more and more frequent.In order to realize data acquisition and information unified management of automation equipment,this paper designs client software based on OPC Da architecture,and verifies the feasibility of equipment communication by taking conveyor control unit as an example.The results of the experiments show that efficient,flexible data acquisition,reading and writing can be completed between application procedures and industrial control equipments.This is a way to acquire data of automation equipments among different workshops and to unify management of information.
