【功能描述】
在输入采样阶段，PLC以扫描方式依次地读入所有输入状态和数据，并将它们存入I/O映象区中的相应得单元内。输入采样结束后，转入用户程序执行和输出刷新阶段。在这两个阶段中，即使输入状态和数据发生变化，I/O映象区中的相应单元的状态和数据也不会改变。因此，如果输入是脉冲信号，则该脉冲信号的宽度必须大于一个扫描周期，才能保证在任何情况下，该输入均能被读入。

控制单元（Control Unit）负责程序的流程管理。正如工厂的物流分配部门，控制单元是整个CPU的指挥控制中心，由指令寄存器IR(Instruction Register)、指令译码器ID(Instruction Decoder)和操作控制器OC(Operation Controller)三个部件组成，对协调整个电脑有序工作极为重要。控制单元可以作为CPU的一部分，也可以安装于CPU外部

【英文介绍】
In the input sampling phase, the PLC successively reads all input status and data by scanning and stores them in the corresponding cell in the I/O image area. After the end of the input sampling, the user program execution and output refresh phase. In both phases, even if the input state and data change, the state and data of the corresponding unit in the I/O map area will not change. Therefore, if the input is a pulse signal, the width of the pulse signal must be greater than one scan cycle to ensure that the input can be read in any case.

The Control Unit is responsible for the flow management of the program. Just like the logistics distribution department in a factory, the control unit is the command and control center of the entire CPU, It is composed of three parts: Instruction Register IR(Instruction Register), instruction Decoder ID(Instruction Decoder) and Operation Controller OC(Operation Controller), which is extremely important to coordinate the orderly work of the whole computer. The control unit can be part of the CPU or installed outside the CPU
