工業上經常使用的PLC種類繁多，對于低端的PLC而言，梯形圖指令大同小異，對于中機，如S7-300，許多程序是用語言表編的。實用的梯形圖有中文符號注解，否則閱讀很困難，看梯形圖前如能大概了解設備工藝或操作過程 ，看起來比較容易。若進行電氣故障分析，一般是應用反查法或稱反推法，即根據輸入輸出對應表，從故障點找到對應PLC的輸出繼電器，開始反查滿足其動作的邏輯關系。經驗表明，查到一處問題，故障基本可以排除，因為設備同時發生兩起及兩起以上的故障點是不多的。

PLC自身故障判斷

一般來說，PLC是極其可靠的設備，出故障率很低，但由于外部原因，也可導致PLC損壞。

一只工作電源為220V的接近開關，其輸入PLC信號觸點兩根引線與接近開關的220V的電 源線共用一根4芯電纜，一次該接近開關損壞，電工更換時，錯把電源的零線與輸入的PLC的公共線調錯，導致送電時燒壞了3路PLC輸入點。

一次系統電源變壓器零線排因腐蝕而中斷，導致接入PLC220V電源升到380V，燒壞了PLC底部的電源模塊，后整改時增加了380/220V的隔離控制變壓器。

西門子S7-200的PLC輸出公共端標1L、2L等，工作電源為AC L1 N 表示，+24V 電源為L+M表示對初學者或經驗不足者容易搞錯。如果錯把L+M當作220V電源端子，送電瞬間即將燒壞 PLC24V電源。

PLC、CPU等硬件損壞或軟件運行出錯的概率幾乎為零，PLC輸入點如不是強電入侵所致，幾乎也不會損壞，PLC輸出繼電器的常開點，若不是外圍負載短路或設計不合理，負載電流超出額定范圍，觸點的壽命也很長。
