摘要
可编程序控制器 PL C与 PC机组成的集散控制系统 ,越来越广泛地应用于生产过程自动化领域 ,要在 WINDOWS平台下实现上下位机与 PL C网络之间的数据通信 ,可采用多种方案。文章介绍了一种 PL C的通信协议 ,利用 VC+ + 6.0中的 Active控件 MSCOMM6.0通信控件方便地实现了微机与 PL C的简易通信。这是一种投资少、经济可靠。
The distributed control system composed of PLC and co mputer is applied more and more widely in the field of product processing automa tion. We can use many ways to realize data communication between Top-Bottom pos ition computer and PLC in the platform of WINDOWS. This paper presents kind of P LC communication agreement and easy realization of a simple and easy communicati on between computer and PLC using Active control and MSCOMM6.0 communication con trol in VC++6.0. This scheme is low investment, high reliability and high perfor mance price ratio.
