描述

在程序执行阶段，即使外部输入信号的状态发生了变化，输入映像寄存器的状态也不会随之而变，输入信号变化了的状态只能在下一个扫描周期的输入处理阶段被读入。
PLC的用户程序由若干条指令组成，指令在存储器中按步序号顺序排列。在没有跳转指令时，CPU从第一条指令开始，逐条顺序地执行用户程序，直到用户程序结束之处。在执行指令时，从输入映像寄存器或别的元件映像寄存器中将有关编程元件的0／1状态读来，并根据指令的要求执行相应的逻辑运算，运算的结果写入到对应的元件映像寄存器中，因此，各编程元件的映像寄存器(输入映像寄存器除外)的内容随着程序的执行而变化。
在输出处理阶段，CP／7将输出映像寄存器的0／1状态传送到输出锁存器。梯形图中某一输出继电器的线圈“通电”时，对应的输出映像寄存器为1状态。信号经输出模块隔离和功率放大后，继电器型输出模块中对应的硬件继电器的线圈通电，其常开触点闭合，使外部负载通电工作。
若梯形图中输出继电器的线圈“断电”，对应的输出映像寄存器为0状态，在输出处理阶段之后，继电器型输出模块中对应的硬件继电器的线圈断电，其常开触点断开，外部负载断电，停止工作。
