1、PLC的基本概念

早期的可編程控制器稱作可編程邏輯控制器（Programmable Logic Controller,PLC），它主要用來代替繼電器實現邏輯控制。隨著技術的發展，這種採用微型計算機技術的工業控制裝置的功能已經大大超過了邏輯控制的範圍，因此，今天這種裝置稱作可編程控制器，簡稱PC。但是為了避免與個人計算機（Personal Computer）的簡稱混淆，所以將可編程序控制器簡稱PLC。PLC自1969年美國數據設備公司（DEC）研制出現，現行美國、日本、德國的可編程序控制器質量優良，功能強大。

2、PLC的基本結構

PLC實質是一種於工業控制的計算機，其硬件結構基本上與微型計算機相同，基本構成為：

a、電源

PLC的電源在整個係統中起著十分重要的作用。如果沒有一個良好的、可靠的電源係統是無法正常工作的，因此PLC的制造商對電源的設計和制造也十分重視。一般交流電壓波動在+10%(+15%）範圍內，可以不採取其它措施而將PLC直接連接到交流電網上去

b、中央處理單元（CPU)

中央處理單元（CPU）是PLC的控制中樞。它按照PLC係統程序賦予的功能接收並存儲從編程器鍵入的用戶程序和數據；檢查電源、存儲器、I/O以及警戒定時器的狀態，並能診斷用戶程序中的語法錯誤。當PLC投入運行時，首先它以掃描的方式接收現場各輸入裝置的狀態和數據，並分別存入I/O映象區，然後從用戶程序存儲器中逐條讀取用戶程序，經過命令解釋後按指令的規定執行邏輯或算數運算的結果送入I/O映象區或數據寄存器內。等所有的用戶程序執行完畢之後，後將I/O映象區的各輸出狀態或輸出寄存器內的數據傳送到相應的輸出裝置，如此循環運行，直到停止運行。

為了進一步提高PLC的可靠性，對大型PLC還採用雙CPU構成冗餘係統，或採用三CPU的表決式係統。這樣，即使某個CPU出現故障，整個係統仍能正常運行。

c、存儲器

存放係統軟件的存儲器稱為係統程序存儲器。

存放應用軟件的存儲器稱為用戶程序存儲器。

d、輸入輸出接口電路

1．現場輸入接口電路由光耦合電路和微機的輸入接口電路，作用是PLC與現場控制的接口界面的輸入通道。

2．現場輸出接口電路由輸出數據寄存器、選通電路和中斷請求電路集成，作用PLC通過現場輸出接口電路向現場的執行部件輸出相應的控制信號。

e、功能模塊

如計數、定位等功能模塊。

f、通信模塊

如以太網、RS485、Profibus-DP通訊模塊等。
