【功能描述】
在輸入采樣階段，PLC以掃描方式依次地讀入所有輸入狀態(tài)和數(shù)據(jù)，并將它們存入I/O映象區(qū)中的相應(yīng)得單元內(nèi)。輸入采樣結(jié)束后，轉(zhuǎn)入用戶程序執(zhí)行和輸出刷新階段。在這兩個階段中，即使輸入狀態(tài)和數(shù)據(jù)發(fā)生變化，I/O映象區(qū)中的相應(yīng)單元的狀態(tài)和數(shù)據(jù)也不會改變。因此，如果輸入是脈沖信號，則該脈沖信號的寬度必須大于一個掃描周期，才能保證在任何情況下，該輸入均能被讀入。

控制單元（Control Unit）負責程序的流程管理。正如工廠的物流分配部門，控制單元是整個CPU的指揮控制中心，由指令寄存器IR(Instruction Register)、指令譯碼器ID(Instruction Decoder)和操作控制器OC(Operation Controller)三個部件組成，對協(xié)調(diào)整個電腦有序工作極為重要。控制單元可以作為CPU的一部分，也可以安裝于CPU外部

【英文介紹】
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
