輸入信號可靠性的提高
要提高現場輸入給PLC的信號的可靠性，首先要選擇可靠性較高的變送器和各種開關，防止各種原因引起傳送信號線短路、斷路或接觸不良。其次在程序設計時增加數字濾波程序，提高輸入信號的可信性。數字信號濾波可采用圖8（a）所示的程序設計方法，在現場輸入觸點后加一定時器，定時時間根據觸點抖動情況和系統的響應速度確定，一般為幾十毫秒，這樣可保證觸點確實穩定閉合后才有其他響應。（http://www.diangon。。ｃｏｍ版權所有）模擬信號濾波可采用圖8（b）所示的程序設計方法，對現場模擬信號連續采樣3次，采樣間隔由A/D轉換速度和該模擬信號的變化速率決定。3次采樣數據分別存放在數據寄存器DT10、DT11、DT12中，當zui后一次采樣結束后，利用數據比較、數據交換、數據段比較指令去掉zui大和zui小值，保留中間值作為本次采樣結果存放在數據寄存器DT0中。
