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。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功能，出現(xiàn)故障時可及時發(fā)出警報信息。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，整個系統(tǒng)將極高的可靠性。
