摘要
概述PLC顺序功能图的功能、组成和编程方法。针对顺序功能图编程系统的设计要求,基于IEC61131-3国际标准的编程规则,采用面向对象的思想,设计出了一套全新的完整易用的数据结构。最后给出了顺序功能图编程系统的设计方案及其基于VC++的方案实现。
The function,composition and programming method of Sequential Function Chart （SFC） were summarized.According to the requirement of the SFC programming system and the IEC61131-3 standard,a suit of data structure was designed based on Object-Oriented Thinking.The design scheme and the implementation based on VC＋＋ for the SFC programming system were given in this paper.
