　plc與PLD關于大多數(shù)操控行業(yè)的朋友們與單片機愛好者，都不是生疏的名詞?？墒悄私馑鼈兊摹耙蛔种睢眴幔考偃缒鷮Υ烁信d趣，就請看看小編今日介紹的內(nèi)容。

　　1.可編程操控器(PLC)是計算機家族中的一員，是為工業(yè)操控應用而規(guī)劃制作的。前期的可編程操控器稱作可編程邏輯操控器，簡稱PLC，它首要用來替代繼電器實現(xiàn)邏輯操控。跟著技能的開展，這種設備的功用已經(jīng)大大超越了邏輯操控的規(guī)模，因而，今日這種設備稱作可編程操控器，簡稱PC。但是為了避免與個人計算機的簡稱混雜，所以將可編程操控器簡稱PLC(ProgRammable Logic Controller)。

　　PLC的首要特點

　　高可靠性、豐富的I/O接口模塊、選用模塊化結(jié)構(gòu)、編程簡略易學、安裝簡略，修理便利

　　PLC的功用

　　邏輯操控、守時操控、計數(shù)操控、步進(次序)操控

　　PID操控

　　數(shù)據(jù)操控：PLC具有數(shù)據(jù)處理才能。

　　通訊和聯(lián)網(wǎng)

　　其它：PLC還有許多特別功用模塊，適用于各種特別操控的要求，如：定位操控模塊，CRT模塊。

　　2.PLD是可編程邏輯器材(ProgramableLogicDevice)的簡稱，fpga是現(xiàn)場可編程門陣列(FieldProgramableGateArray)的簡稱，兩者的功用根本相同，只是實現(xiàn)原理略有不同，所以咱們有時能夠疏忽這兩者的差異，統(tǒng)稱為可編程邏輯器材或PLD/FPGA。

　　PLD是電子規(guī)劃領域中最具活力和開展前途的一項技能，它的影響一點點不亞于70年代單片機的發(fā)明和運用。PLD能做什么呢？能夠毫不夸張的講，PLD能完結(jié)任何數(shù)字器材的功用，上至高性能cpu,下至簡略的74電路，都能夠用PLD來實現(xiàn)。

　　PLD好像一張白紙或是一堆積木，工程師能夠經(jīng)過傳統(tǒng)的原理圖輸入法，或是硬件描繪語言自由的規(guī)劃一個數(shù)字系統(tǒng)。經(jīng)過軟件仿真，咱們能夠事先驗證規(guī)劃的正確性。在pcb完結(jié)以后，還能夠利用PLD的在線修正才能，隨時修正規(guī)劃而不必改動硬件電路。運用PLD來開發(fā)數(shù)字電路，能夠大大縮短規(guī)劃時刻，削減PCB面積，進步系統(tǒng)的可靠性。

　　典型的PLD由一個“與”門和一個“或”門陣列組成，而任意一個組合邏輯都能夠用“與一或”表達式來描繪，所以，PLD能以乘積和的方式完結(jié)大量的組合邏輯功用.這一階段的產(chǎn)品首要有PAL(可編程陣列邏輯)和GAL(通用陣列邏輯)。

　　關于可編程邏輯器材，規(guī)劃人員可利用價格低廉的軟件工具快速開發(fā)、仿真和測試其規(guī)劃。然后，可快速將規(guī)劃編程到器材中，并當即在實際運行的電路中對規(guī)劃進行測試。原型中運用的PLD器材與正式生產(chǎn)終究設備(如網(wǎng)絡路由器、DSL調(diào)制解調(diào)器、DVD播放器、或轎車導航系統(tǒng))時所運用的PLD完全相同。這樣就沒有了NRE成本，終究的規(guī)劃也比選用定制固定邏輯器材時完結(jié)得更快。

　　選用PLD的另一個要害長處是在規(guī)劃階段中客戶可根據(jù)需求修正電路，直到對規(guī)劃作業(yè)感到滿足為止。這是因為PLD基于可重寫的存儲器技能--要改動規(guī)劃，只需求簡略地對器材進行從頭編程。一旦規(guī)劃完結(jié)，客戶可當即投入生產(chǎn)，只需求利用終究軟件規(guī)劃文件簡略地編程所需求數(shù)量的PLD就能夠了。
