現(xiàn)場模擬量信號經(jīng)A／D轉(zhuǎn)換后變成離散的數(shù)字信號，然后將形成的數(shù)據(jù)按時間序列存入PLC內(nèi)存。再利用數(shù)字濾波程序?qū)ζ溥M行處理，濾去噪聲部分獲得單純信號， 可對輸入信號用m次采樣值的平均值來代替當(dāng)前值，但井不是通常的每采樣。次求一次平均值，而是每采樣一次就與近的m－l次歷史采樣值相加，此方法反應(yīng)速度快，具有很好的實時性，輸入信號經(jīng)過處理后用干信號顯示或回路調(diào)節(jié)，有效地抑制了噪聲干擾。

由干工業(yè)環(huán)境惡劣，干擾信號較多， I／ O信號傳送距離較長，常常會使傳送的信號有誤。為提高系統(tǒng)運行的可靠性，使PLC在信號出錯倩況下能及時發(fā)現(xiàn)錯誤，并能排除錯誤的影響繼續(xù)工作，在程序編制中可采用軟件容錯技術(shù)。
