摘要
文章以监控计算机与可编程控制器(PLC)数据通信的研究为理论基础,针对专用行车电气控制装置存在的问题,提出了实时监控的方法,给出了在Visual Basic 6.0环境下实现上位机与西门子S7-200系列PLC通信的思路,通过对相关理论和技术的分析、应用,设计出监控界面,开发了通信程序。实践表明,这种通信方式具有一定的工程应用价值和参考价值。
On the basis of communication between monitoring computer time monitoring mode to the question of line vehicle apparatus and idea and PLC, the paper introduces real of realizing communication between host computer and SIEMENS＇S7-200 PLC with VB6.0. In the paper monitoring interface is designed and the communication program is compiled by analyzing and using some theories and technique. It has been proved by the application that the communication model has certain application and reference value for projects.
