输入扫描  在这一阶段中，PLC以扫描方式读入所有输入端子上的输入信号，并将输入信号存入输入映像区，输入映像存储器被刷新。在程序执行阶段和输出刷新阶段中，输入映像存储器与外界隔离，其内容保持不变，直至下一个扫描周期的输入扫描阶段，才被重新读入的输入信号刷新。可见，PLC在执行程序和处理数据时，不直接使用现场当时的输入信号，而使用本次采样时输入到映像区中的数据。如果输入设备能使PLC输入端形成闭合回路，对应输入端编号的内部输入继电器内保存为“1”，即相当于继电器线圈导通。在程序执行过程中，该编号对应的触点动作；如果输入设备能使输入开路，则对应输入端编号的内部输入继电器内保存为“0”，即相当于继电器线圈没导通，在程序执行过程中，该编号对应的触点不动作。如果在PLC处于非输入扫描的阶段，PLC外的输入设备状态发生了变化，内部输入继电器也不会发生变化，要等到下一个输入扫描阶段才能根据此时的输入状态来刷新。所以，对于少于十几毫秒的输入信号，经常采集不到。
