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 values 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.
