VB下的PLC通讯以及在壁面清洗机器人监控中的应用

COMMUNICATION BETWEEN PLC AND PC COMPUTER UNDER VB ENVIRONMENT AND ITS APPLICATION IN CONTROL SYSTEM OF WALL CLEANING MOBILE ROBOT

结合 OMRON CQM1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 PL C与上位计算机通讯程序的设计方法和使用要点 .

This paper describes the design method for the communication program between PLC and PC computer in the monitor system of wall cleaning robot under 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 VB languages. Finally, one application is analyzed to verify the feasibility of this kind of design method.
