normal align=left>对于用户来说，在编写用户程序或选择设备时，必须清楚下面介绍的三个阶段，即用户程序执行过程的原理。
PLC采用集中处理的方法，即对输入扫描信号、执行用户程序和输出刷新都采用集中分批处理的工作方式。
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。
在程序执行过程中，同一周期内，前面的逻辑结果影响后面的触点，即后执行的程序可能用到前面的**中间运算结果；但同一周期内，后面的运算结果不影响前面的逻辑关系。该扫描周期内除输入继电器以外的所有内部继电器的**终状态（导通与否），将影响下一个扫描周期各触点的开与闭。
（3）输出刷新 程序执行阶段的运算结果被存入输出映像区，而不送到输出端口上。在输出刷新阶段，PLC将输出映像区中的输出变量送入输出锁存器，然后由锁存器通过输出模块产生本周期的控制输出。如果内部输出继电器的状态为“1”，则输出继电器触点闭合。全部输出设备的 。
