Screen 7:
Screen 7 shows a simple example of the display change using
an internal limit value comparison. The screen shows two
numerical values that show the output values (QV output) of
the timing relay T08. The variable type is DWord. The timing
relay is run in a loop from 0 to 10 seconds.
A value range from 0 to 11000 is defined in the Number range/
format tab. The unit of measure is set to “s” (seconds). The
scaling range is defined from 0 to 11 with 2 decimal places.
The display change is active and is detected via the internal
limit value comparison. The numerical value display flashes
for the left numerical value and is inverted for the right
numerical value.

Left
numerical
value:
The numerical value flashes in the range from 0 to 3 and from 7 to 10.
The upper limit value is set to 7 (the display change occurs from numerical value 7 to
10) in the Display change tab and the lower limit value is set to 3 (the display change
occurs from numerical value 0 to 3).
There is therefore no display change between 3 and 7.
Right
numerical
value:
The numerical value is inverted in the range from 0 to 3 and from 7 to 10.
The upper limit value is set to 7 (the display change occurs from numerical value 7 to
10) in the Display change tab and the lower limit value is set to 3 (the display change
occurs from numerical value 0 to 3).
There is therefore no display change between 3 and 7.
