對于西門子PLC S7-1500系列的輸出點，若動作對象所對應的指示燈不亮，首先確認PLC是否運行。在確定PLC在運行狀態下，那么說明此動作對象的PLC輸入輸出邏輯功能沒有滿足，也就是說輸入回路出故障，先要檢查輸入回路。若所對應的指示燈亮，但所對應的執行元件如電磁閥、西門子S7-1500模塊上電面板三個指示燈不亮接觸器不動作，先查電磁閥控制電源及保險器，***簡便的方法，用電筆去量所對應PLC輸出點的公共端子。電筆不亮，可能對應保險絲熔斷等電源故障。電筆亮，說明電源是好的，所對應的電磁閥、接觸器、線路出故障。

　如果指示燈不亮，但對應的電磁閥、接觸器等動作，這可能此輸出點因過載或短路燒牢。這時應把此輸出點的外接線拆下來，再用萬用表電阻檔去量輸出點與公共端的電阻，若電阻較小，說明此觸點已壞，若電阻無窮大，說明此觸點是好的，應是所對應的輸出指示燈已壞。
