基于工业局域网的微机与PLC数据通信实现方法

Implementing Method for Data Communication between Micro Computer and PLC Based on Industrial Local Network

以美国A－B公司PLC2系列为例，介绍了一种借助VisualBasic通信控件编制微机与工业。PLC之间数据通信软件的方法。对于不同系列的PLC均能用此法简易地开发出实现微机与PLC通信的软件。

Taking PLC2 series of A-B company of U. S. A. as example,the author introduces a method for editing data communication software between micro computer and PLC with the help of visual Basic communication control software. For different series ol PLC,the software for implementing communication between micro computer and PLC can be developed simply and easily by using of this method.
