Linear Scaling
The Scale (Linear) function can be used to:
• Convert analog field input signals from the range which is native to the
analog input module to an application specific range.
• Make other linear conversions in ranges appropriate to the application.
Select the Input and Output tags appropriate
for the application. Convert raw input signals
to engineering units for use in the program, or
convert engineering units to output signals for
control purposes
