a．控制單元的冗余

（1）重要的過(guò)程單元：CPU（包括存儲(chǔ)器）及電源均應(yīng)1B1冗余。

（2）在需要時(shí)也可選用PLC硬件與熱備軟件構(gòu)成的熱備冗余系統(tǒng)、2重化或3重化冗余容錯(cuò)系統(tǒng)等。

b． I/O接口單元的冗余

（1）控制回路的多點(diǎn)I/O卡應(yīng)冗余配置。

（2）重要檢測(cè)點(diǎn)的多點(diǎn)I/O卡可冗余配置。3）根據(jù)需要對(duì)重要的I/O信號(hào)，可選用2重化或3重化的I/O接口單元。

PLC輸入/輸出滯后時(shí)間

輸入/輸出滯后時(shí)間又稱(chēng)系統(tǒng)響應(yīng)時(shí)間，是指可編程序控制器的外部輸入信號(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)間三部分組成。

輸入模塊的CPU濾波電路用來(lái)濾除由輸入端引入的干擾噪聲，消除因外接輸入觸點(diǎn)動(dòng)作是產(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(lèi)型有關(guān)，繼電器型輸出電路的滯后時(shí)間一般在10ms左右；雙向可空硅型輸出電路在負(fù)載接通時(shí)的滯后時(shí)間約為1ms，負(fù)載由導(dǎo)通到斷開(kāi)時(shí)的最大滯后時(shí)間為10ms；晶體管型輸出電路的滯后時(shí)間約為1ms。由掃描工作方式引起的滯后時(shí)間最長(zhǎng)可達(dá)到兩個(gè)多掃描周期?？删幊绦蚩刂破骺偟捻憫?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可編程序控制器或采取其他措施。
