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，用來在其內部存儲執(zhí)行邏輯運算、順序運算、計時、計數(shù)和算術運算等操作的指令，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)生產的各個領域，機械加工企業(yè)為了提高生產效率，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線。隨著產品機型的更新?lián)Q代，生產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.模塊化的結構,使其在工業(yè)生產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。
