一、摘要 PLC是一種專門在工業(yè)環(huán)境下應用而設計的數(shù)字運算操作的電子裝置。

它采用可以編制程序的存儲器，用來在其內(nèi)部存儲執(zhí)行邏輯運算、順序運算、計時、計數(shù)和算術(shù)運算等操作的指令，并能通過數(shù)字式或模擬式的輸入和輸出，控制各種類型的機械或生產(chǎn)過程。PLC及其有關的外圍設備都應按照易于與工業(yè)控制系統(tǒng)形成一個整體，易于擴展其功能的原則而設計。在工業(yè)生產(chǎn)的各個領域，機械加工企業(yè)為了提高生產(chǎn)效率，采用機械化流水作業(yè)的方式，對不同類型的零件分別組成的自動生產(chǎn)線。隨著產(chǎn)品機型的更新?lián)Q代，生產(chǎn)線承擔的加工對象也隨之改變，這就需要改變控制程序，使生產(chǎn)線的機械設備按新的工藝過程運行，而繼電接觸器控制器系統(tǒng)是采用固定接線，很難適應這個要求。大型自動生產(chǎn)線的控制系統(tǒng)使用的繼電器數(shù)量很多，隨著PLC的應用日益普及,其使用方法簡單,便于掌握,且可靠性,抗干擾性很強,自身具有完善的功能.模塊化的結(jié)構(gòu),使其在工業(yè)生產(chǎn)線上的應用越來越廣泛。

　　發(fā)展趨勢：1.向高速度、大容量方向發(fā)展

　　為了提高PLC的處理能力，要求PLC具有的響應速度和更大的存儲容量。目前，有的PLC的掃描速度可達0.1ms/k步左右。PLC的掃描速度已成為很重要的一個性能指標。

　　在存儲容量方面，有的PLC可達幾十兆字節(jié)。為了擴大存儲容量，有的公司已使用了磁泡存儲器或硬盤。

　　2.向超大型、超小型兩個方向發(fā)展

　　當前中小型PLC比較多，為了適應市場的多種需要，今后PLC要向多品種方向發(fā)展，特別是向超大型和超小型兩個方向發(fā)展?，F(xiàn)已有I/O點數(shù)達14336點的超大型PLC，其使用32位微處理器，多CPU并行工作和大容量存儲器，功能強。

輸入/輸出滯后時間又稱系統(tǒng)響應時間，是指PLC部輸入信號發(fā)生變化的時刻至它控制的有關外部輸出信號發(fā)生變化的時刻之間的時間間隔，它由輸入電路濾波時間、輸出電路的滯后時間和因掃描工作方式產(chǎn)生的滯后時間這三部分組成。

      輸入模塊的RC濾波電路用來濾除由輸入端引入的干擾噪聲，因外接輸入觸點動作時產(chǎn)生的抖動引起的不良影響，濾波電路的時間常數(shù)決定了輸入濾波時間的長短，其典型值為10ms左右。

      輸出模塊的滯后時間與模塊的類型有關，繼電器型輸出電路的滯后時間一般在10ms左右;雙向晶閘管型輸出電路在負載通電時的滯后時間約為1ms，負載由通電到斷電時的滯后時間為10ms;晶體管型輸出電路的滯后時間一般在1ms以下。

      PLC總的響應延遲時間一般只有幾十ms，對于一般的系統(tǒng)是無關緊要的。要求輸入輸出信號之間的滯后時間盡量短的系統(tǒng)，可以選用掃描速度快的PLC或采取其他措施。
