PLC的硬件主要由中央處理器（CPU）、存儲(chǔ)器（RAM、ROM）、輸入接口、輸出接口、通信接口、電源和編程器等幾部分組成。其中：CPU是PLC的核心；I/O接口用來連接輸入和輸出設(shè)備；通信接口用于連接編程器和上位機(jī)；電源為 PLC各部分提供電能。PLC的故障主要來自于PLC故障和PLC外部設(shè)備故障。PLC故障包括中央處理單元故障、電源故障和接口故障。中央處理單元故障包括 CPU 故障、存儲(chǔ)器故障和系統(tǒng)總線故障。接口故障包括輸入接口電路故障、輸出接口電路故障和通信接口電路故障。輸入/輸出設(shè)備故障有按鈕、接近開關(guān)、行程開關(guān)、傳感器、接觸器和電磁閥等故障。

　　在PLC控制系統(tǒng)中，PLC內(nèi)部的CPU、存儲(chǔ)器、系統(tǒng)總線的故障率比較低，發(fā)生故障較多的是PLC的輸入電路、輸出電路、電源模塊和通信模塊等部位，更多故障發(fā)生于輸入、輸出設(shè)備。維修時(shí)，只要PLC電源指示燈、RUN/STOP指示燈、SF指示燈亮滅正常，就不要懷疑PLC發(fā)生故障。如果通過診斷程序確認(rèn)運(yùn)算程序有輸出，而PLC的物理接口沒有輸出，那么輸出接口電路或輸出設(shè)備存在故障。因此，維修PLC時(shí)，首先要判別是外部設(shè)備故障還是PLC本身故障。
