摘要
利用VisualC ++开发PLC梯形图编辑功能的仿真软件 ,模拟PLC编程器的功能。该软件能够实现梯形图符号的编辑、语法检查、逻辑错误检查等功能 ,具有学习和应用的实际价值。本软件使用二叉树和链表数据结构 ,实现了梯形图语言和语句表语言的互换算法。
The simulation software which can simulate the function of PLC program tracer is developed with Visual C++ This software can realize the function of editing, syntax checking and logic errors checking with Ladder Graphics, and has the practical value of learning and applications Using the data structure of Binary Tree and catenulate table, this software realize the arithmetic of interchanging between the Ladder Graphics language and sentence table language
