一、摘要 PLC是一種專門在工業(yè)環(huán)境下應用而設計的數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、計數和算術運算等操作的指令，并能通過數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換代，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已有I/O點數達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。
