VB平台下PLC与微机间通讯程序设计及其应用

The communication between PLC and microcomputer under the VB environment and its application in the control system of the wall cleaning mobile robot

结合ＯＭＲＯＮＣＱＭ１型可编程控制器特点，通过壁面清洗机器人监控系统的具体程序，系统地阐述了ＶＢ下的ＰＬＣ与上位计算机通讯程序的设计方法，以及在使用过程中的要点和技巧。

This paper describes the design method of the communication program between PLC and PC computer in the monitor system of wall cleaning robot under the MS VB environment, referring to the characteristics of PLC' s architecture and programming on the OMRON CQM1 programmable logic computer. The outline and technique in programming are emphasized when the communication interface programs are designed with the VB languages. Finally, an application is analyzed to verify the feasibility of this kind of design method.
