摘要
针对各PLC生产厂家生产PLC专用顺序控制指令的不同,应用各种型号PLC都具有的计数器指令提出一种通用的顺序控制编程方法。阐述了该方法的基本思想,详细说明了不同顺序功能图结构的程序设计方法。
In view of each PLC Manufacturer which produce a dedicated PLC sequential control instruction is different,applied the counter instruction which each kind of type PLC provides a common programming method for sequential control.Described the basic idea of the method,detailed description of the different structure of sequential function chart programming method.
