在内部处理阶段,PLC检查CPU.模块内部的硬件是否正常,将监控定时器复位,以及完成一些其它内部工作。

在通信服务阶段,PLC与其它的带微处理器的智能装置通信,响应编程器键入的命令,更新编程器的显示内容。

当PLC处于停止(STOP)模式时,只执行以上的操作。PLC处于运行(RUN)模式时,还要完成另外三个阶段的操作。

在PLC的存储器中,设置了一片区域用来存放输入信号和输出信号的状态,它们分别称为输入映像寄存器和输出映像寄存器。PLC梯形图中的其他编程元件也有对应的映像存储区,它们统称为元件映像寄存器。

在输入处理阶段,PLC把所有外部输入电路的接通,断开状态读入输入映像寄存器。外部输入电路接通时,对应的输入映像寄存器为l状态,梯形图中对应的输入继电器的常开触点接通,常闭触点断开。外部输入触点电路断开时,对应的输入映像寄存器为0状态,梯形图中对应的输入继电器的常开触点断开,常闭触点接通。

某一编程元件对应的映像寄存器为l状态时,称该编程元件为ON,映像寄存器为0状态时,称该编程元件为OFF。

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。
