The circuit diagram contains timing relay T01 which triggers
counter C02. When the counter reaches the upper switch
threshold SH, it switches output Q1 to 1. The value of the
counter's function block output QV is transferred to marker
word MW06. The upper setpoint SH is associated with marker
word MW07 and the preset actual value SV with marker word
MW05. In RUN mode, the marker words are where the actual
data is stored and where new data is written via the value
entry elements. The counter can be reset at any time via input
I2. I1 (rising edge) is used to accept the value in marker word
MW05 as a new preset actual value SV. As there is no
setpoint value in marker word MW07 (switch value for Q1)
when the program is started, this is interpreted as switch value
“zero”, and output Q1 is switched immediately to 1.

Screen 1:
Screen 1 illustrates the value entry option using the set
variable marker word MW07 (switch value for Q1). The value
entry element is enlarged on the display. A value range from
0 to 9999 and Allow digit selection as input format are defined
in the Number range/format tab. Input I01 is assigned make
contact bit logic in the Operability tab. The value is written to
marker word 7 and accepted by counter input SH. Q1 is set to
1 if the counter actual value QV is greater than or equal to the
upper setpoint SH. If the actual value already has a higher
value than the switch value you can reset the counter via I2.
Q1 is immediately reset to 0 and is not active again until the
switch value is reached.
