are the same or greater than
Activation day and Activation month settings, output
Q
is activated and remains active till the date reaches the set
Deactivation day and
Deactivation month settings.
Activation of the
BLOCK
input deactivates the function output whereas the
activation of the
FREEZE
input freezes the output. The
BLOCK
input always has a
higher priority than the
FREEZE
input.
The module automatically handles the leap day and different month lengths.
• The function output remains active during the leap day if the leap day falls within
the set activation period.
• If the set
Activation day is not a valid date (for example, 31st April), then the
output does not activate.
• If the set Deactivation day is not a valid date (for example, 31st April), then the
last date of the month is considered.

3.20.4.5 Application
The function activates an output for a specific set duration of the calendar year.
Consider an application where the output of the daily timer function DTMGAPC
needs to be activated only for specific days of the calendar year. The output of
CALGAPC can be connected to the
BLOCK
input of DTMGAPC (using NOT gate) so
that DTMGAPC activates only for the duration defined by CALGAPC.
