The alarm delay determines how long a ´To-Off-Normal` or a ´To-Normal` transition
must exist before an alarm is generated. Entering an alarm delay time of 10 seconds
means that the limit value must be exceeded for at least 10 seconds before this
datapoint generates an alarm. If the limit value only lasts for 7 seconds, then no
alarm occurs. The alarm handling for a datapoint can be completely disabled by
setting the alarm delay time to a value of 100000 or higher.
