Time comparator
This module compares the current day and time with the respective day activation
hour
xxx Act hour and activation minute xxx Act Min settings. When the time of the day
reaches the set activation time, output
Q
is activated. It remains activate for the
duration defined by the setting xxx Act Dur .
The output remains active until the next day if the setting for xxx Act
Dur is set such that it results into rollover of the day.
Different activation and deactivation times can be set for all days of the week. The
activation and deactivation can also be disabled for a specific day, for example, if the
activation or deactivation is not needed on Sundays, the
Sunday Act enable can be set
"False".
Activation of the
BLOCK
input deactivates the function output whereas the activation
of
FREEZE
input freezes the output. The
BLOCK
input has always a higher priority
than the
FREEZE
input.
3.16.4.5 Application
The daily timer function is useful in applications that require signal activation and
deactivation at a specific time of the day. Different activation times and duration can
be set for different days of the week. For example, if the signal should be active on
Mondays between 7.15 a.m. and 4 p.m., the
Monday Act enable setting should be
"1=True", Mon Act hour and Mon Act Mn as "07" for hours and "15" for minutes
respectively and Mon Act Dur should be "525" minutes. The behavior of output Q is
illustrated in Figure 88 .
