Good Afternoon. I am working with a point IO setup with a couple temperature sensors, and pressure transmitters. I am using a 1734-IE8C Point io module. Under the scaling, I have my level sensor setup for 0-100 engineering units. I would like to get better resolution, so i started changing it from 100 to 1000, and 10000 max units. when I do this, my reading doesn't scale correctly.
My current reading is showing 46".
0-100 shows 46
0-1000 shows 475
0-10000 shows 4755
I don't know if this is a rounding issue, a firmware issue, or just something I need to deal with. I don't know what is actually the true number.
running a scaling calculation in excel, I get the same number every time, with greater resolution. I am using 3277 and 16383 as the min and max inputs from the manual.
The calculation I am using is the following
Rate = (scaled_max-scaled_min)/(input_max-input_min)
output = (input-input_min)*rate+scaled_min
There is not much information on AB's site, or KB about the 1734-IE8C.
Thanks for any help,
Kenneth
