本章用到的软件是博途15.1，根据实物与指令的结合讲解，PLC选择S7-1200
简单指令：
1、常开触点
PLC中的常开触点对应按钮的常开触点
2、常闭触点
PLC中的常闭触点对应按钮的常闭触点
3、线圈
PLC中的线圈对应接触器及中间继电器的线圈
现有三台电机，要求按顺序启动，逆序停止
第一台电机启动后，第二台电机才能启动，第二台电机启动后第三台电机才能启动。第一台没启动的话，第二台也启动不了。一定是按顺序的。
逆序停止时当三台电机全部启动后，按照逆序停止电机，也就是说第三台电机停止后第二台电机才能停止，第二台电机停止后第一台电机才能停止。
首先画出主回路（简单的画一下，没加热保护，有的断路器是自带保护的）
不用PLC的控制回路
