摘要
介绍了系统的工作原理,建立了信息交流和控制的系统结构,将面向对象和基于事件驱动的处理方法应用于通信协议的建立和通信控制过程。结合具体通信控制单元三菱PLC和FX IN-232-BD与PC串口RS-232C的通信,编写了算法和通信控制的代码,经实验证明,通信控制系统运行可靠。
The principle of system object-oriented and event-based has been introduced, the communication and control architecture has been established, and the methods have been used to set the communication protocol and control process. For the communication among PLC made by Mitsubishi, FXIN 232 BD and RS-232C in PC, the algorithms and communication and control codes have been designed. By experiment testing, the communication and control system can robustly work.
