摘要
在实际工业控制系统应用环境中,研究PLC自由口模式的通信有助于实现PLC与Windows程序开发环境间的实时通信。通过研究PLC自由口模式的通信,系统实现了C++Builder6.0与PLC的实时通信,从而实现工业控制系统中上下位机的通信,将由PLC采集的的数据进行实时显示和控制,并将数据以数据库的形式存储起来以便研究和分析。
In real industry control system application environment, it＇ s helpful to realize the real - time communication between PLC and Windows. According to research on free - mode communication of PLC, this system has achieved real - time communication between C ＋ ＋ Builder 6.0 and PLC： So as to achieve up and down machine communication in industry control system, display and control the data collected by PLC software in real- time and save the data to databese for research and analysis.
