、延遲輸入法
IN—輸入
OUT—輸出
TIME（ET）—延時(shí)時(shí)間
TON—延時(shí)輸出（其曲線如下圖)
注釋：當(dāng)輸入IN=1時(shí)，啟動計(jì)數(shù)器直到計(jì)時(shí)時(shí)間（PT）=延時(shí)時(shí)間，OUT=1。當(dāng)計(jì)數(shù)器計(jì)時(shí)時(shí)間〈延時(shí)時(shí)間，OUT=0。延時(shí)時(shí)間{zh0}取1S以內(nèi)。
優(yōu)點(diǎn)：xc了短時(shí)的周期干擾。
缺點(diǎn)：響應(yīng)速度慢，不利于信號的快速傳輸。
二、減少模擬量輸入擾動的方法
1、限幅法
MOVE—移動保持指令（使能端EN=1，OUT=IN。EN=0，OUT保持前次值）
GE—大于等于指令（OUT=1，IF IN1≥IN2）
LE—小于等于指令（OUT=1，IF IN1≤IN2）
HL—上限設(shè)定值
LL—下限設(shè)定值
注釋：當(dāng)模擬量輸入信號在HL和LL之間時(shí)，OUT=IN。當(dāng)IN-AI信號超出或等于HL或LL時(shí)，GE或LE判斷IN-AI信號，使OUT1或OUT2輸出“1”去封MOVE，從而保持MOVE的輸出為HL或LL的設(shè)定值。也就起到了限幅的作用。
優(yōu)點(diǎn)：能有效克服因偶然因素引起的脈沖干擾。
缺點(diǎn)：平滑度差。
2、延遲濾波限幅法
MOVE—移動保持指令（使能端EN=1，OUT=IN。EN=0，OUT保持前次值）
GE—大于等于指令（OUT=1，IF IN1≥IN2）
LE—小于等于指令（OUT=1，IF IN1≤IN2）
HL—上限設(shè)定值
LL—下限設(shè)定值
LG—延遲濾波指令（其曲線如下圖）
TIME—延遲濾波時(shí)間
注釋：功能基本和限幅法相同，只是在輸入端增加了一個延遲濾波器，對輸入信號起到了延遲緩沖的濾波。
優(yōu)點(diǎn)：有效地抑制了周期性的脈沖干擾。平滑度比限幅法有所改善。
缺點(diǎn)：信號響應(yīng)速度減緩。
