Screen 8:
Screen 8 shows an example of the output of a marker word.
The numerical value in the screen is associated with the
marker word MW01. The variable type is Word.
A value range of 0 to 999 is defined in the Number range/
format tab. The timing relay T09 switches the counter C01
(
a
Circuit diagram in CL-SOFT.) every two seconds. The
counter function block output QV writes the data into the
marker word MW01 (specified in the Parameters tab,
function block output area). The counter is reset if the upper
switch value SH (38) is reached.
Screen 9:
Screen 9 shows an example of a value overflow display. The
associated variable is the QV output of the timing relay T04.
The variable type is DWord. The timing relay runs from
0 to 4000 ms. Only a value range from 0 to 3000 and the
measuring unit “ms” are defined on the Number range/
format tab. This will cause a value overflow as soon as
3000 ms is exceeded. This is indicated in the display by an
overflow display.
Screen 10:
Screen 10 shows an example of a value underflow display.
The associated variable is the QV output of the counter C02.
The variable type is DWord. The counter C02 is activated by
timing relay T07 with Flashing mode selected. The counter
runs down from 12 to 0. Only a value range of 6 to 12 and a
unit of measure “mm” is defined on the Number range/
format tab. This causes a value underflow as soon the value
goes below 6 mm. This is indicated in the display by an
underflow display.
