The alarm timer function:
The alarm timer function regards the period until the alarm timer is set after measured value
(PV) or deviation exceeds the alarm set value as a non-alarm state and outputs an alarm after
the alarm timer setting time elapses.
The alarm timer starts being activated if the alarm is turned on. In addition, if the alarm state
is released while the alarm timer is being activated, no alarm is output.
