PLC采用 “ 顺序扫描、不断循环 ” 的工作方式， 这个过程可分为输入采样，程序执行、输出刷新三个阶段 ，整个过程扫 描并执行一次所需的时间称为扫描周期。
输入采样阶段：PLC在输入采样阶段，以扫描方式顺序读入所有输入端的通/断状态或输入数据，并将此状态存入输入状态寄存器，即输入刷新。接着转入程序执行阶段。在程序执行期间，即使输入状态发生变化，输入状态寄存器的内容也不会改变，只有在下一个扫描周期的输入处理阶段才能被读入 。程序执行阶段：PLC 在执行阶段，按先左后右，先上后下的步序，执行 程序指令。其过程如下：从输入状态寄存器和其它元件 状态寄存器中读出有关元件的通 / 断状态，并根据用户程 序进行逻辑运算，运算结果再存入有关的状态寄存器中。
由 PLC 的工作过程可见，在 PLC 的程序执行阶段，即使输入发生了变化，输入状态寄存器的内容也不会立即改变，要 等到下一个周期输入处理阶段才能改变。暂存在输出状态寄存器中的输出信号，等到一个循环周期结束， CPU 集中将 这些输出信号全部输出给输出锁存器，这才成为实际的 CPU 输出。因此全部输入、输出状态的改变就需要一个扫描周 期，换言之，输入、输出的状态保持一个扫描周期。
