Time comparator
This module compares the current day and time with the activation hour and minute
defined with the settings xxx Act hour and xxx Act Mn, respectively. When the time of
the day reaches the set activation time, output Q is activated and remains active for the
duration defined by the setting xxx off delay.
The output remains active until the next day if the value for xxx off
delay is set so 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 setting Sunday Act enable can
be set as "False".
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.

Application

DTMGAPC 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 and 16:00, the Monday Act enable setting should be "True", Monday Act
hour should be "7", Monday Act Mn should be "15", and Monday off delay should be
"525" minutes. The behavior of output Q is illustrated in
Q
03:00 06:00
Set Monday Act hour = 07 hrs
Set Monday Act Mn = 15 min
Set Monday off delay = 525 min
