ALSTOM–V0701596-001102 輸出刷新階段則是根據(jù)運(yùn)算和邏輯處理的結(jié)果

ALSTOM–V0701596-001102 可編程邏輯控制器（PLC）的工作原理可以分為三個(gè)階段，即輸入采樣、用戶程序執(zhí)行和輸出刷新。這三個(gè)階段被稱為一個(gè)掃描周期。在PLC運(yùn)行期間，CPU會(huì)以一定的掃描速度重復(fù)執(zhí)行這三個(gè)階段。

在輸入采樣階段，PLC會(huì)讀取所有輸入端子的狀態(tài)，并將其存儲(chǔ)在內(nèi)部存儲(chǔ)器中。用戶程序執(zhí)行階段則是PLC根據(jù)內(nèi)部存儲(chǔ)器中的程序指令進(jìn)行運(yùn)算和邏輯處理，得出結(jié)果。輸出刷新階段則是根據(jù)運(yùn)算和邏輯處理的結(jié)果，刷新所有輸出端子的狀態(tài)，控制設(shè)備的動(dòng)作。

此外，PLC的CPU相當(dāng)于人的大腦，存儲(chǔ)器是存儲(chǔ)文件的，I/O功能則相當(dāng)于人的五官，可以掃描文件并打印出來(lái)。編程器則用于用戶程序的編制、調(diào)試檢查和監(jiān)視，還可以通過(guò)鍵盤(pán)調(diào)用和顯示PLC的一些內(nèi)部狀態(tài)和系統(tǒng)參數(shù)。電源是提供PLC的能源。

總的來(lái)說(shuō)，ALSTOM–V0701596-001102 PLC是一種專門(mén)為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作電子系統(tǒng)。通過(guò)編寫(xiě)程序?qū)懭氪鎯?chǔ)器，然后由內(nèi)部CPU進(jìn)行運(yùn)算、計(jì)算、定時(shí)及算術(shù)等操作來(lái)實(shí)現(xiàn)對(duì)設(shè)備和機(jī)械的動(dòng)作控制。

ALSTOM- V0701596-001102 The working principle of a programmable logic controller (PLC) can be divided into three stages, namely input sampling, user program execution and output refresh. These three stages are called a scan cycle. During the operation of the PLC, the CPU will repeat these three stages at a certain scanning speed.

During the input sampling phase, the PLC reads the state of all input terminals and stores it in internal memory. In the execution stage of the user program, the PLC performs operations and logical processing according to the program instructions in the internal memory and obtains the results. In the output refresh phase, the state of all output terminals is refreshed according to the results of calculation and logical processing, and the action of the device is controlled.

In addition, the CPU of the PLC is equivalent to the human brain, the memory is to store files, and the I/O function is equivalent to the human features, which can scan files and print them out. The programmer is used for the preparation of the user program, debugging inspection and monitoring, and can also call and display some internal status and system parameters of the PLC through the keyboard. The power supply is the energy source that provides the PLC.

In general, the ALSTOM- V0701596-001102 PLC is a digital arithmetic operation electronic system specially designed for applications in industrial environments. By writing a program into the memory, and then by the internal CPU operation, calculation, timing and arithmetic operations to achieve the control of equipment and machinery.
