SFC则是根据机械的动作流程设计顺序的方式完成编程，适合于机械动作设备的编程。ST结构文本具有与C语言等相似的语法构造、文本形式的程序语言，可以采用条件语句进行选择分支、利用循环语句进行重复，程序编辑很简洁、清楚，适合于具有计算机基础的人员。结构化梯形图可以使用触点、线圈、功能、功能模块等回路符号，将程序以图形的形式描述的语言，容易直观理解，因此普遍用于顺控程序。按照工程类型，简单工程一般采用指令表、梯形图和SFC这三种语言，其中梯形图应用的比较多，结构化工程可以采用梯形图、ST、SFC以及FBD。

下面我就这两点进行解释。电线规格电线的规格，就是线方了——电线的横截面积，单位平方毫米，简称平方或方——这句话精简成了两个字“线方”。线方的排列是跳跃性增长的，且没有规律可循。比如有1平方的电线，1.5平方的电线，却没有2平方的电线；有2.5平方的电线，却没有3平方和3.5平方的电线。好在家用电线的线方不超过10平方，而10平方以内的电线一共只有五种，所以记忆起来并不难：1平方、1.5平方、2.5平方、4平方、6平方。
