摘要
研究一种实现内装型可编程机床控制器（ＰＭＣ）顺序控制功能的新方法。采用Ｃ语言的双向链表数据结构描述和记录用户所编制的梯形图，从而将梯形图的全屏幕编辑功能转换成双向链表的规范化操作。经汇编后生成内部指令码线性表，实现循环扫描控制，其处理方法简捷，运行稳定可靠。
A new way is developed to realize the se quence control for built-in PMC. Double linked list data structure programmed by C language to describe and record ladder diagram programmed by users, which can convert whole screen function for ladder diagram into standard operation after assembling.Internal code linear table was created and adopted to achieve cycle-scanning control. The processing method is simple and stable in running.
