Staggering of weight AM2 Input

Hi,

I need help with the coiling of a weight, it is being used to perform a filling process, the weight has a 4-20 mA output, with an operating range of 0 to 100 Kg, being 4mA / 0 Kg, and 20 mA / 100 kg I need this to be as accurate as possible, and show the information on a basic KTP700 screen, which is already configured just need to know how to perform the appropriate staging,

Using Logo V8 and module AM2 Input

Thank you !.

 You already know scaling i believe. Only by continuous testing you can make it accurate with offsets you may find during the testing process.

Yes, I commented that the most accurate way was to do a staggering from 400 to 2000, being 400 = 0 Kg, and 2000 = 100 Kg, however I would like to know if it is possible to do a direct escolanamiento. The problem that I face is that the logo can not operate real variables, 

 Yes that is true. Logo cannot operate real variables. So you cannot use decimal values. Direct scaling is possible. You can select the sensor as 4-20mA and set the values as 0-100. If you need better resolution, you can set the values as 0-1000 and divide by 10 after scaling.

Here's an example with  displaying the weight with one decimal place.

For simulation:

Value of AI1:

200 = 0.0 kg = 4 mA

600 = 50.0 kg = 12 mA

1000 = 100.0 kg = 20 mA
