Posted 7 May 2021 There really is not much logic to it. The temperature shows up in a register for each of the 4 inputs: Input 1 is in word n+1 Input 2 is in word n+2 Input 3 is in word n+3 Input 4 is in word n+4 n = 2000 + 10 x unit number. So if the unit number dialed in on the front of the card is 3 and you are looking for the current value of input 2, then you would look in address 2032. Explaining - n = 2000 + 10 * 3 = 2030. Input 2 is word n+2, 2030 + 2 = 2032. then you use that number for whatever purpose that you need. Here is the manual: https://www.fa.omron.com.cn/data_pdf/mnu/w368-e1-10_cs1w-p____cj1w-p___.pdf?id=1644 Look in section 3-3. Share this post Link to post Share on other sites
