IF  Variation <= 100 THEN  //此處判斷指令不執(zhí)行，Variation實(shí)際值小于等于100時(shí)該程序下端的DADDP指令沒(méi)有任何動(dòng)作
            DADDP(M8012,Speed_Ton,1,Speed_Ton);
            IF Speed_Ton >= 20 THEN
                Speed_er:=1;
            END_IF;    
        ELSE
            Speed_er:=0;
            (*Speed_Ton:=0;*)
        END_IF;

看看是不是用了中文輸入法的標(biāo)點(diǎn)符號(hào)
