a．控制單元的冗余

（1）重要的過程單元：CPU（包括存儲器）及電源均應1B1冗余。

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

b． I/O接口單元的冗余

（1）控制回路的多點I/O卡應冗余配置。

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

PLC輸入/輸出滯后時間

輸入/輸出滯后時間又稱系統(tǒng)響應時間，是指可編程序控制器的外部輸入信號發(fā)生變化的時刻至它控制的有關外部輸出信號發(fā)生變化的時刻之間的時間間隔，它由輸入電路濾波時間、輸出電路的滯后時間和因掃描工作方式產(chǎn)生的滯后時間三部分組成。

輸入模塊的CPU濾波電路用來濾除由輸入端引入的干擾噪聲，消除因外接輸入觸點動作是產(chǎn)生的抖動引起的不良影響，濾波電路的時間常數(shù)決定了輸入濾波時間的長短，其典型值為10ms左右。

輸出模塊的滯后時間與模塊的類型有關，繼電器型輸出電路的滯后時間一般在10ms左右；雙向可空硅型輸出電路在負載接通時的滯后時間約為1ms，負載由導通到斷開時的最大滯后時間為10ms；晶體管型輸出電路的滯后時間約為1ms。由掃描工作方式引起的滯后時間最長可達到兩個多掃描周期?？删幊绦蚩刂破骺偟捻憫舆t時間一般只有幾十ms，對于一般的系統(tǒng)是無關緊要的。要求輸入—輸出信號之間的滯后時間盡量短的系統(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。
