How to scale an Analog Input from Scale Change Block
Which analog module your are using S800 or S700 ? for S700 no need to use scal block you can do scaling @ module parameterisation.
Incase you are suing S800 I/O modules use readily availabel block to scale your input.
Check associated app here.
If it's S800 analog I/O, find scalling details below
These values are on the assumption that you are using S800 I/O using GSD, and using CI840 or CI801?
SCALE START INPUT = -7120
SCALE END INPUT = 32704 OR more if not getting accuracy try 32752
SCALE START OUTPUT = 5
SCALE END OUTPUT = 300 ( e.g. temp range 5-300'C)Hope that helps
