Select the same current range as in the data
source (connected device).
Select the input variable.
Specify the number of decimal places.
Assign a useful name, e.g. the parameter
name that the data source also uses.
Enter the measuring range. The lower and
upper range values are assigned to the 0 or
4 mA value and the 20 mA value
respectively. The system uses the
engineering unit which you entered
beforehand.
