一般講，PLC分為箱體式和模塊式兩種。但它們的組成是相同的，對箱體式PLC，有一塊CPU板、I/O板、顯示面板、內存塊、電源等，當然按CPU性能分成若干型號，并按I/O點數(shù)又有若干規(guī)格。對模塊式PLC，有CPU模塊、I/O模塊、內存、電源模塊、底板或機架。無任哪種結構類型的PLC，都屬于總線式開放型結構，其I/O能力可按用戶需要進行擴展與組合。PLC的基本結構框圖如下：
一、CPU的構成
PLC中的CPU是PLC的核心，起神經中樞的作用，每臺PLC至少有一個CPU，它按PLC的系統(tǒng)程序賦予的功能接收并存貯用戶程序和數(shù)據，用掃描的方式采集由現(xiàn)場輸入裝置送來的狀態(tài)或數(shù)據，并存入規(guī)定的寄存器中，同時，診斷電源和PLC內部電路的工作狀態(tài)和編程過程中的語法錯誤等。進入運行后，從用戶程序存貯器中逐條讀取指令，經分析后再按指令規(guī)定的任務產生相應的控制信號，去指揮有關的控制電路，
與通用計算機一樣，主要由運算器、控制器、寄存器及實現(xiàn)它們之間聯(lián)系的數(shù)據、控制及狀態(tài)總線構成，還有外圍芯片、總線接口及有關電路。它確定了進行控制的規(guī)模、工作速度、內存容量等。內存主要用于存儲程序及數(shù)據，是PLC不可缺少的組成單元。
CPU的控制器控制CPU工作，由它讀取指令、解釋指令及執(zhí)行指令。但工作節(jié)奏由震蕩信號控制。
CPU的運算器用于進行數(shù)字或邏輯運算，在控制器指揮下工作。
CPU的寄存器參與運算，并存儲運算的中間結果，它也是在控制器指揮下工作。
CPU雖然劃分為以上幾個部分，但PLC中的CPU芯片實際上就是微處理器，由于電路的高度集成，對CPU內部的詳細分析已無必要，我們只要弄清它在PLC中的功能與性能，能正確地使用它就夠了。
CPU模塊的外部表現(xiàn)就是它的工作狀態(tài)的種種顯示、種種接口及設定或控制開關。一般講，CPU模塊總要有相應的狀態(tài)指示燈，如電源顯示、運行顯示、故障顯示等。箱體式PLC的主箱體也有這些顯示。它的總線接口，用于接I/O模板或底板，有內存接口，用于安裝內存，有外設口，用于接外部設備，有的還有通訊口，用于進行通訊。CPU模塊上還有許多設定開關，用以對PLC作設定，如設定起始工作方式、內存區(qū)等。 PLC資料網
二、I/O模塊：
PLC的對外功能，主要是通過各種I/O接口模塊與外界聯(lián)系的，按I/O點數(shù)確定模塊規(guī)格及數(shù)量，I/O模塊可多可少，但其最大數(shù)受CPU所能管理的基本配置的能力，即受最大的底板或機架槽數(shù)限制。I/O模塊集成了PLC的I/O電路，其輸入暫存器反映輸入信號狀態(tài)，輸出點反映輸出鎖存器狀態(tài)。
三、電源模塊：
有些PLC中的電源，是與CPU模塊合二為一的，有些是分開的，其主要用途是為PLC各模塊的集成電路提供工作電源。同時，有的還為輸入電路提供24V的工作電源。電源以其輸入類型有：交流電源，加的為交流220VAC或110VAC，直流電源，加的為直流電壓，常用的為24V。
四、底板或機架：
大多數(shù)模塊式PLC使用底板或機架，其作用是：電氣上，實現(xiàn)各模塊間的聯(lián)系，使CPU能訪問底板上的所有模塊，機械上，實現(xiàn)各模塊間的連接，使各模塊構成一個整體。
五、PLC 的外部設備
外部設備是PLC系統(tǒng)不可分割的一部分，它有四大類
1. 編程設備：有簡易編程器和智能圖形編程器，用于編程、對系統(tǒng)作一些設定、監(jiān)控PLC及PLC所控制的系統(tǒng)的工作狀況。編程器是PLC開發(fā)應用、監(jiān)測運行、檢查維護不可缺少的器件，但它不直接參與現(xiàn)場控制運行。
2. 監(jiān)控設備：有數(shù)據監(jiān)視器和圖形監(jiān)視器。直接監(jiān)視數(shù)據或通過畫面監(jiān)視數(shù)據。
3. 存儲設備：有存儲卡、存儲磁帶、軟磁盤或只讀存儲器，用于永久性地存儲用戶數(shù)據，使用戶程序不丟失，如EPROM、EEPROM寫入器等。
4. 輸入輸出設備：用于接收信號或輸出信號，一般有條碼讀人器，輸入模擬量的電位器，打印機等。
六、PLC的通信聯(lián)網
PLC具有通信聯(lián)網的功能，它使PLC與PLC 之間、PLC與上位計算機以及其他智能設備之間能夠交換信息，形成一個統(tǒng)一的整體，實現(xiàn)分散集中控制。現(xiàn)在幾乎所有的PLC新產品都有通信聯(lián)網功能，它和計算機一樣具有RS-232接口，通過雙絞線、同軸電纜或光纜，可以在幾公里甚至幾十公里的范圍內交換信息。
當然，PLC之間的通訊網絡是各廠家專用的，PLC與計算機之間的通訊，一些生產廠家采用工業(yè)標準總線，并向標準通訊協(xié)議靠攏，這將使不同機型的PLC之間、PLC與計算機之間可以方便地進行通訊與聯(lián)網。
了解了PLC的基本結構，我們在購買程控器時就有了一個基本配置的概念，做到既經濟又合理，盡可能發(fā)揮PLC所提供的最佳功能。
