電源中央處理單元
中央處理器由控制器、運(yùn)算器和寄存器組成，這些電路都集中在一塊芯片上，通過(guò)地址總線(xiàn)、控制總線(xiàn)與存儲(chǔ)器的輸入/輸出接口電路相連。中央處理器的作用是處理和運(yùn)行用戶(hù)程序，進(jìn)行邏輯和數(shù)學(xué)運(yùn)算，控制整個(gè)系統(tǒng)使之協(xié)調(diào)。 [6]
存儲(chǔ)器
存儲(chǔ)器是具有記憶功能的半導(dǎo)體電路，它的作用是存放系統(tǒng)程序、用戶(hù)程序、邏輯變量和其他一些信息。其中系統(tǒng)程序是控制PLC實(shí)現(xiàn)各種功能的程序，由PLC生產(chǎn)廠(chǎng)家編寫(xiě)，并固化到只讀存儲(chǔ)器(ROM)中，用戶(hù)不能訪(fǎng)問(wèn)。 [6]
輸入單元
輸入單元是PLC與被控設(shè)備相連的輸入接口，是信號(hào)進(jìn)入PLC的橋梁，它的作用是接收主令元件、檢測(cè)元件傳來(lái)的信號(hào)。輸入的類(lèi)型有直流輸入、交流輸入、交直流輸入。 [6]
輸出單元
輸出單元也是PLC與被控設(shè)備之間的連接部件，它的作用是把PLC的輸出信號(hào)傳送給被控設(shè)備，即將中央處理器送出的弱電信號(hào)轉(zhuǎn)換成電平信號(hào)，驅(qū)動(dòng)被控設(shè)備的執(zhí)行元件。輸出的類(lèi)型有繼電器輸出、晶體管輸出、晶閘門(mén)輸出。 [6]
PLC除上述幾部分外，根據(jù)機(jī)型的不同還有多種外部設(shè)備，其作用是幫助編程、實(shí)現(xiàn)監(jiān)控以及網(wǎng)絡(luò)通信。常用的外部設(shè)備有編程器、打印機(jī)、盒式磁帶錄音機(jī)、計(jì)算機(jī)等。
(2)編程容易。PLC的編程多采用繼電器控制梯形圖及命令語(yǔ)句，其數(shù)量比微型機(jī)指令要少得多，除中、高檔PLC外，一般的小型PLC只有16條左右。由于梯形圖形象而簡(jiǎn)單，因此容易掌握、使用方便，甚至不需要計(jì)算機(jī)專(zhuān)業(yè)知識(shí)，就可進(jìn)行編程。 [8]
(3)組態(tài)靈活。由于PLC采用積木式結(jié)構(gòu)，用戶(hù)只需要簡(jiǎn)單地組合，便可靈活地改變控制系統(tǒng)的功能和規(guī)模，因此，可適用于任何控制系統(tǒng)。 [8]
(4)輸入/輸出功能模塊齊全。PLC的最大優(yōu)點(diǎn)之一，是針對(duì)不同的現(xiàn)場(chǎng)信號(hào)(如直流或交流、開(kāi)關(guān)量、數(shù)字量或模擬量、電壓或電流等)，均有相應(yīng)的模板可與工業(yè)現(xiàn)場(chǎng)的器件(如按鈕、開(kāi)關(guān)、傳感電流變送器、電機(jī)啟動(dòng)器或控制閥等)直接連接，并通過(guò)總線(xiàn)與CPU主板連接。 [8]
(5)安裝方便。與計(jì)算機(jī)系統(tǒng)相比，PLC的安裝既不需要專(zhuān)用機(jī)房，也不需要嚴(yán)格的屏蔽措施。使用時(shí)只需把檢測(cè)器件與執(zhí)行機(jī)構(gòu)和PLC的I/O接口端子正確連接，便可正常工作。 [8]
近年來(lái)，微處理器的使用，特別是隨著單片機(jī)大量采用，大大增強(qiáng)了PLC的能力，并且使PLC與微型機(jī)控制系統(tǒng)之間的差別越來(lái)越小，特別是高檔PLC更是如此。
