在本站中看到s7-300中0-10V對(duì)應(yīng)端口0-27648,

那么S7-200中4~20mA對(duì)應(yīng)多少?

因200系列的模塊所使用的電流為0-20mA，而對(duì)應(yīng)的單極性數(shù)據(jù)為0-32000
因此每mA對(duì)應(yīng)的為32000/20=1600

按此對(duì)應(yīng)關(guān)系，4-20mA對(duì)應(yīng)的為：1600*4~1600*20=6400~32000

以上！

Good Luck！

在cvlsam的指點(diǎn)下我感到在一點(diǎn)點(diǎn)進(jìn)步,希望我能早一天編出完整的程序.

cvlsam的資料來(lái)源是否如圖?

都是高手哦！

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

雖然沒(méi)用到,還是謝謝,學(xué)習(xí)了

看看應(yīng)用手冊(cè)就可以了。
