第一類故障點也是故障最多的地點)在繼電器、接觸器

如某生產線PLC控制系統的日常維護中，電氣備件消耗量最大的為各類繼電器或空氣開關。除了產品本身質量原因之外，主要是由于現場環境比較惡劣。例如，暴露于生產環境中的接觸器觸點易打火或氧化，逐漸發熱變形，直至不能使用。該生產線所有現場的控制箱都是選用密閉性較好的盤柜，其內部元器件較其他采用敞開式盤柜內元器件的使用壽命明顯要長。所以避免此類故障應盡量選用高性能繼電器，并改善元器件使用環境，就可以減少更換的頻率，降低對系統運行的影響。

第二類故障多發點在閥門或閘板這一類的設備上

因為這類設備的執行機構相對位移較大；或者傳動結構復雜，機械、電氣、液壓等各環節稍有不到位就會產生誤差或故障。在長期的運行狀態下，如果缺乏運行維護，易造成閥體部件的卡，堵，漏等現象。因此在系統運行時要加強對此類設備的巡檢，發現問題及時處理。我廠對此類設備建立了嚴格的點檢制度，定期檢查閥門是否變形，執行機構是否靈活可用，控制器是否有效等，很好地保證了整個控制系統的有效性。
