PLC自身故障判斷
一般來說，PLC是極其可靠的設(shè)備，出故障率很低。PLC的CPU等硬件損壞或軟件運(yùn)行出錯的概率幾乎為零；PLC輸入點(diǎn)如不是強(qiáng)電入侵所致，幾乎也不會損壞；PLC輸出繼電器的常開點(diǎn)，若不是外圍負(fù)載短路或設(shè)計(jì)不合理，負(fù)載電流超出額定范圍，觸點(diǎn)的壽命也很長。

因此，我們查找電氣故障點(diǎn)，重點(diǎn)要放在PLC的外圍電氣元件上，不要總是懷疑PLC硬件或程序有問題，這對快速維修好故障設(shè)備、快速恢復(fù)生產(chǎn)是十分重要的，因此筆者所談的PLC控制回路的電氣故障檢修，重點(diǎn)不在PLC本身，而是PLC所控制回路中的外圍電氣元件。
