摘要
为解决控制领域软硬件之间数据通信困难的问题,提高实时数据访问的性能,本文对OPC数据存取规范进行了深入研究,重点分析了自动化接口标准,结合Visual Basic语言相对容易,开发周期短等特点,故采用Visual Basic作为开发语言,设计并实现了基于VB的OPC客户端应用软件。通过测试,OPC客户端软件取得了不错的通信效果。
With the purpose to solve the difficulties of data communication between software and hardware in control field,and improve thefunction of real-timedata accessing,this papermainlystudies on theOPC data access specification and then analyses deeply the standard of the automation interface.Combing with Visual Basic that is is relativelyeasy,short development cycle and so on.SO the paperuseVisualBasicasdevepment language,design andimplement OPCclient application softwarebased on Visual Basic.Through the test,OPC client software achieved good communication effect.
