摘要
论述了在编写梯形图时基本指令和步进指令各自体现的优缺点,举例说明了二者结合后用顺序控制的方法实现基本指令控制给编程带来的方便。
This paper aims to discuss both the advantages and disadvantages that the basic instructions and step instructions showed during the ladder diagram＇s drawing. At the same time, some examples in the paper illustrate that the basic instructions with order-control technique make the programming process more convenient after the basic instructions are combined with the step instructions.
