工業(yè)生產對控制設備的可靠性要求：
①平均故障間隔時間長
②故障修復時間（平均修復時間）短
任何電子設備產生的故障，通常為兩種：
①偶發(fā)性故障。由于外界惡劣環(huán)境如電磁干擾、超高溫、超低溫、過電壓、欠電壓、振動等引起的故障。這類故障，只要不引起系統(tǒng)部件的損壞，一旦環(huán)境條件恢復正常，系統(tǒng)也隨之恢復正常。但對PLC而言，受外界影響后，內部存儲的信息可能被破壞。
②*性故障。由于元器件不可恢復的破壞而引起的故障。
如果能限制偶發(fā)性故障的發(fā)生條件，如果能使PLC在惡劣環(huán)境中不受影響或能把影響的后果限制在zui小范圍，使PLC在惡劣條件消失后自動恢復正常，這樣就能提高平均故障間隔時間；如果能在PLC上增加一些診斷措施和適當的保護手段，在*性故障出現時，能很快查出故障發(fā)生點，并將故障限制在局部，就能降低PLC的平均修復時間。為此，各PLC的生產廠商在硬件和軟件方面采取了多種措施，使PLC除了本身具有較強的自診斷能力，能及時給出出錯信息，停止運行等待修復外，還使PLC具有了很強的抗*力。
