PLC用軟件功能取代了繼電器控制系統(tǒng)中大量的中間繼電器、時間繼電器、計數(shù)器等器件,使控制柜的設(shè)計、安裝、接線工作量大大減少。
PLC的梯形圖程序一般采用順序控制設(shè)計法來設(shè)計。這種編程方法很有規(guī)律,很容易掌握。對于復(fù)雜的控制系統(tǒng),設(shè)計梯形圖的時間比設(shè)計相同功能的繼電器系統(tǒng)電路圖的時間要少得多。
PLC的用戶程序可以在實驗室模擬調(diào)試,輸入信號用小開關(guān)來模擬,通過PLC上的發(fā)光二極管可觀察輸出信號的狀態(tài)。完成了系統(tǒng)的安裝和接線后,在現(xiàn)場的統(tǒng)調(diào)過程中發(fā)現(xiàn)的問題一般通過修改程序就可以解決,系統(tǒng)的調(diào)試時間比繼電器系統(tǒng)少得多。
PLC的故障率很低,且有完善的自診斷和顯示功能。PLC或外部的輸入裝置和執(zhí)行機構(gòu)發(fā)生故障時,可以根據(jù)PLC上的發(fā)光二極管或編程器提供的信息迅速地查明故障的原因,用更換模塊的方法可以迅速地排除故
