在本站中看到s7-300中0-10V對應端口0-27648, 那么S7-200中4~20mA對應多少? |

因200系列的模塊所使用的電流為0-20mA,而對應的單極性數據為0-32000 因此每mA對應的為32000/20=1600 按此對應關系,4-20mA對應的為:1600*4~1600*20=6400~32000 以上! Good Luck! |

實際上S7200的有效精度是0~4000,不過要做一次轉換,200的模擬量是12位的只不過她用的內部位不是從0~11的位地址,所以顯示的適合是0~32000,其實最好的方法就是自己通過程序處理,把他轉換到0~4000(電流輸出時是0~2000,最高位始終是1) |
