摘要
针对PLC的顺序控制编程,提出了一种基于任意存储单元的步控制字编程方法,不仅编程简单容易,而且速度快、直观易读、调试方便,还具有很强的通用性和灵活性。阐述了该方法的原理、程序结构,同时给出了常用的分支及合并顺序控制逻辑的程序结构图。
A new method based on step control word is proposed for PLC＇ s sequence control programming. It uses memory location to store the step which is going, not only easy to program, read and debug but also fast, flexible and universal, The principle and the structure are discussed and the flow charts for branch and parallel control are described.
