采用具有锁存、译码、驱动功能的芯片CD4513驱动共阴极LED七段显示器，两只CD4513的数据输入端A～D共用PLC的4个输出瑞，其中A为最低位，D为最高位。LE是锁存使能输入端，在LE信号的上升沿将数据输入端输入的BCD数锁存在片内的寄存器中，并将该数译码后显示出来。如果输入的不是十进制数，显示器熄灭。LE为高电平时，显示的数不受数据输入信号的影响。显然，N个显示器占用的输出点数为P=4＋N。

如果PLC使用继电器输出模块，应在与CD4513相连的PLC各输出端接一下拉电阻，以避免在输出继电器的触点断开时CD4513的输入端悬空。PLC输出继电器的状态变化时，其触点可能抖动，因此应先送数据输出信号，待该信号稳定后，再用LE信号的上升沿将数据锁存进CD4513

步骤一“输入状态检查”：PLC首先检查输入端元件所连接之各点开关或传感器状态（1 或0 代表开或关），并将其状态写入内存中对应之位置Xn。步骤二“程式执行”：将阶梯图程式逐行取入CPU 中运算，若程式执行中需要输入接点状态，CPU直接自内存中查询取出。输出线圈之运算结果则存入内存中对应之位置，暂不反应至输出端Yn。步骤三“输出状态更新”：将步骤二中之输出状态更新至PLC输出部接点，并且重回步骤一。 此三步骤称为PLC之扫描周期，而完成所需的时间称为PLC 之反应时间，PLC 输入讯号之时间若小于此反应时间，则有误读的可能性。每次程式执行后与下一次程式执行前，输出与输入状态会被更新一次，因此称此种运作方式为输出输入端“程式结束再生”。
