marker word MW07 and the preset actual value SV with
marker word MW05. During RUN mode the current data is
stored in the marker words and new data is written there via
the value entry elements. Input I2 can be used to reset the
counter at any time. I1 (rising edge) is used to accept the value
at marker word MW05 as a new preset actual value SV. As no
value is stored in marker word MW07 (switch value for Q1)
when the program is started, this is interpreted as switch value
“zero” and the output Q1 is immediately set to “high”.

Screen 1:
Screen 1 illustrates the value entry option via the set variable
marker word MW 07 (switch value for Q1). The value entry
element is shown enlarged on the display. A value range is
defined from 0 to 9999 in the Number range/format tab and
Allow Digit Selection is set as entry mode. The input I01 is
selected with N/O contact bit logic on the Operability tab.
The value is written to the marker word 7 and transferred by
counter input SH. Q1 is high when the counter input value
QV equals or is greater than the upper set value SH. If the
actual value is already higher than the switch value, you can
reset the counter via I2. Q1 switches immediately to low and
is not set again until the switch value is reached.
Screen 2:
Screen 2 illustrates the value entry option via the set variable
marker word MW05 (preset actual value SV). After you have
entered a new value this is written to the marker word
MW05 by actuating I1. This is associated with the preset
actual value SV of the counter C02. After the transfer, the
actual value QV jumps to the entered SV value and counts on
from there.
