Alarm delay
An alarm can become effective with a delay: the alarm output is set only after elapse of the adjusted
delay time, provided that the limit value is still exceeded. Shorter alarms than the adjusted delay are
ignored.
Signal change monitoring
Another limit value processing function is signal change monitoring (per minute).
