sample logic

hi 

i require omron plc CJ2M-CPU31 sample logic for RTD card CJ1W-PTS52

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.
