● Create an assignment between the measured mass value and the output value by setting
these parameters:
>
Output
>
>
Function block 1 - analog input
Channel:
Measured value (primary variable)
>
>
>
Measured value scaling
Start of scale value:
Full scale value:
as in "wor
king range"
as in "working range"
>
>
>
Output scaling
Unit:
Start of scale value:
Full scale value:
Unit of mass [kg, g, t ...]
as "measured value scaling" * density
as "measured value scaling" * density
You can also adjust the output to another process value. Assign the required unit to the
parameters under the rubric output scaling. Assign the start of scale and full scale values
according to the measured value scaling.
