PLC 硬(ying)件(jian)故障主要指 PLC 系(xi)統中的模板、電(dian)路損壞(huai)而造成的故障。　4，軟件故障。
PLC 軟(ruan)件故(gu)障包(bao)含(han)軟(ruan)件錯誤(wu)、操作錯誤(wu)等。 PLC 軟(ruan)件故(gu)障一般可(ke)以(yi)通(tong)過 PLC 本(ben)身 的自(zi)診(zhen)斷測試功能或(huo)者(zhe)軟(ruan)件來查看(kan)、檢(jian)查。二，PLC 控(kong)制系統故障率情況。1) CPU 與存(cun)儲器故(gu)障率(lv)占(zhan) 5%。2) I/O模塊故(gu)障率(lv)占 15%。3)傳感器及(ji)開關故障率(lv)占(zhan) 45%。4)執(zhi)行(xing)器故障率(lv)占 30%。5)接線等(deng)其他方(fang)面故障(zhang)率占 5%。
