| Abstract: | Visual C has advantages such as powerful functions, quick communication capability, and good Real-time properties. The theory and approach of serial communication based on Visual C are introduced from two aspects-Computer and Omron PLC. According to the multi-thread characteristics of serial communication between interfaces in Industrial control systems, some programming techniques of communication modularization are described in detail with factual application. The application results show these techniques are simple, stable, and reliable. |
