輸入/輸出滯后時(shí)間又稱系統(tǒng)響應(yīng)時(shí)間，是指PLC部輸入信號(hào)發(fā)生變化的時(shí)刻至它控制的有關(guān)外部輸出信號(hào)發(fā)生變化的時(shí)刻之間的時(shí)間間隔，它由輸入電路濾波時(shí)間、輸出電路的滯后時(shí)間和因掃描工作方式產(chǎn)生的滯后時(shí)間這三部分組成。
輸入模塊的RC濾波電路用來(lái)濾除由輸入端引入的干擾噪聲，因外接輸入觸點(diǎn)動(dòng)作時(shí)產(chǎn)生的抖動(dòng)引起的不良影響，濾波電路的時(shí)間常數(shù)決定了輸入濾波時(shí)間的長(zhǎng)短，其典型值為10ms左右。
輸出模塊的滯后時(shí)間與模塊的類型有關(guān)，繼電器型輸出電路的滯后時(shí)間一般在10ms左右;雙向晶閘管型輸出電路在負(fù)載通電時(shí)的滯后時(shí)間約為1ms，負(fù)載由通電到斷電時(shí)的滯后時(shí)間為10ms;晶體管型輸出電路的滯后時(shí)間一般在1ms以下。
PLC總的響應(yīng)延遲時(shí)間一般只有幾十ms，對(duì)于一般的系統(tǒng)是無(wú)關(guān)緊要的。要求輸入輸出信號(hào)之間的滯后時(shí)間盡量短的系統(tǒng)，可以選用掃描速度快的PLC或采取其他措施。
