Screen 3 - Screen 3 shows an example of outputting analog values (here IA3)
on the display. Note the Scaling range field on the Number range/format tab.
The screen contains three numerical value that output the analog value in
different formats. The values are associated with the analog input IA3
(Associated variable tab) which has a value provided as a DWord variable at the
QV output (FB parameter).
All numerical values are assigned a value range from 0 to 1019 as this scan
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 which is an extension of screen 3. For greater simplicity, all
the basic settings of the scaling range were taken from screen 3.
Note the Numerical display setting in the Display change area of the Number
range/format tab.
Table 5.18 Numerical value - analog value output
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), signed
Table 5.20 Numerical value - extended analog value output
Numerical value 1:
Display of the analog value (0 to 1019)
