所謂順序控制是指生產(chǎn)設(shè)備及生產(chǎn)過程,根據(jù)工藝要求按照邏輯運算、順序操作、定時和計算數(shù)等規(guī)則通過預(yù)先編制的程序,在現(xiàn)場輸入信號(包括開關(guān)量、模擬量)的作用下,執(zhí)行機構(gòu)按預(yù)定程序動作,實現(xiàn)以開關(guān)量為主的自動控制。我廠PLC的設(shè)計安裝就是根據(jù)這一原則來實現(xiàn)的。其輸入主要是靠按鈕、行程開關(guān)、限位開關(guān)、動斷觸點等開關(guān)量為主的控制、信號。輸出為繼電器、電磁閥等驅(qū)動元件。PLC內(nèi)部控制部分有定時器、計數(shù)器、中間繼電器等元器件以及許多的常開、常閉觸點 。而傳統(tǒng)的順序控制是由繼電器控制屏來實現(xiàn)的,由于設(shè)備體積大、功耗高、動作速度緩慢、接線復(fù)雜、通用性、靈活性差、維護工作量大、故障頻發(fā)率高而導(dǎo)致可靠性差,沒有計算和儲存功能,而PLC控制系統(tǒng)克服了繼電器控制的弱點,把計算機技術(shù)與繼電器控制有機地結(jié)合起來,為工業(yè)自動化提供了十分完美的現(xiàn)代化控制裝置,其*性主要表現(xiàn)在:
