PLC內(nèi)部具有豐富的軟元件，如定時器、計數(shù)器、輔助繼電器等，利用它們來設計一些程序，可以屏蔽輸入元件的誤信號，防止輸出元件的誤動作。在設計應用程序時，可以利用"看門狗"方法實現(xiàn)對系統(tǒng)各組成部分運行狀態(tài)的監(jiān)控。如用PLC控制某一運動部件時，編程時可定義一個定時器作"看門狗"用，對運動部件的工作狀態(tài)進行監(jiān)視。定時器的設定值，為運動部件所需要的zui大可能時間。在發(fā)出該部件的動作指令時，同時啟動"看門狗"定時器。若運動部件在規(guī)定時間內(nèi)達到位置，發(fā)出一個動作完成信號，使定時器清零，說明監(jiān)控對象工作正常；否則，說明監(jiān)控對象工作不正常，發(fā)出報警或停止工作信號。
