為適應(yīng)工業(yè)環(huán)境使用，與一般控制裝置相比較，PLC機(jī)有以下特點(diǎn)：

1. 可靠性高，抗*力強(qiáng)

    工業(yè)生產(chǎn)對(duì)控制設(shè)備的可靠性要求：

①平均故障間隔時(shí)間長(zhǎng)

②故障修復(fù)時(shí)間（平均修復(fù)時(shí)間）短

任何電子設(shè)備產(chǎn)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(dòng)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(fù)正常，系統(tǒng)也隨之恢復(fù)正常。但對(duì)PLC而言，受外界影響后，內(nèi)部存儲(chǔ)的信息可能被破壞。

     ②*性故障。由于元器件不可恢復(fù)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(dòng)恢復(fù)正常，這樣就能提高平均故障間隔時(shí)間；如果能在PLC上增加一些診斷措施和適當(dāng)?shù)谋Ｗo(hù)手段，在*性故障出現(xiàn)時(shí)，能很快查出故障發(fā)生點(diǎn)，并將故障限制在局部，就能降低PLC的平均修復(fù)時(shí)間。為此，各PLC的生產(chǎn)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(qiáng)的自診斷能力，能及時(shí)給出出錯(cuò)信息，停止運(yùn)行等待修復(fù)外，還使PLC具有了很強(qiáng)的抗*力。
