当所有程序执行完毕后，进入输出处理阶段。在这一阶段里，PLC将输出映
象寄存器中与输出有关的状态（输出继电器状态）转存到输出锁存器中，并
通过一定方式输出，驱动外部负载。

因此，PLC在一个扫描周期内，对输入状态的采样只在输入采样阶段进行。
当PLC进入程序执行阶段后输入端将被封锁，直到下一个扫描周期的输入采样
阶段才对输入状态进行重新采样。这方式称为集中采样，即在一个扫描周期内，
集中一段时间对输入状态进行采样。

在用户程序中如果对输出结果多次赋值，则最后一次有效。在一个扫描周期
内，只在输出刷新阶段才将输出状态从输出映象寄存器中输出，对输出接口进
行刷新。在其它阶段里输出状态一直保存在输出映象寄存器中。这种方式称
为集中输出。

对于小型PLC，其I/O点数较少，用户程序较短，一般采用集中采样、集中输出的
工作方式，虽然在一定程度上降低了系统的响应速度，但使PLC工作时大多数时
间与外部输入/输出设备隔离，从根本上提高了系统的抗干扰能力，增强了系统
的可靠性
