Screen 3:
Screen 3 shows an example of the output of analog values
(here IA3) on the display. Note the Scaling Range area on the
Number range/format tab.
This screen contains three numerical values that output the
analog value in different formats. The values are associated
via analog input IA3 (Associated variable tab) which
provides a value as variable type DWord on the QV output
(FB parameter) for further processing. All numerical values
have a value range between 0 and 1019 since this scanning
range is defined by the connected potentiometer.

Screen 4:
Screen 4 shows an example of the output of analog values
(here IA3) on the display and is an extension of screen 3. To
keep it simple all the basic settings of the scaling range from
screen 3 were used.
Note the Numerical display group in the Display change area
on the Number range/format tab.
Numerical
value 1: Display of the analog value (0 to 1019)
Numerical
value 2: Display of the analog value with the scaling
range 0 to 10, two decimal places, unit of
measure “V” (Volt)
Numerical
value 3: Display of the analog value with the scaling
range -5 to +5, two decimal places, unit of
measure “V” (Volt), sign displayed
Analog input I3
