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
