高可靠性是電氣控制設(shè)備的關(guān)鍵性能。PLC由于采用現(xiàn)代大規(guī)模集成電路技術(shù),采用嚴(yán)格的生產(chǎn)工藝制造,內(nèi)部電路采取了先進(jìn)的抗干擾技術(shù),具有很高的可靠性。例如三菱公司生產(chǎn)的F系列PLC平均無故障時(shí)間高達(dá)30萬小時(shí)。一些使用冗余CPU的PLC的平均無故障工作時(shí)間則更長(zhǎng)。從PLC的機(jī)外電路來說,使用PLC構(gòu)成控制系統(tǒng),和同等規(guī)模的繼電接觸器系統(tǒng)相比,電氣接線及開關(guān)接點(diǎn)已減少到數(shù)百甚至數(shù)千分之一,故障也就大大降低。此外,PLC帶有硬件故障自我檢測(cè)功能,出現(xiàn)故障時(shí)可及時(shí)發(fā)出警報(bào)信息。在應(yīng)用軟件中,應(yīng)用者還可以編入外圍器件的故障自診斷程序,使系統(tǒng)中除PLC以外的電路及設(shè)備也獲得故障自診斷保護(hù)。這樣,整個(gè)系統(tǒng)具有極高的可靠性也就不奇怪了。
