How to re-enable an unacknowledge alarm?

Greetings All,

I have a situation where an alarm will occur, and while we can resolve the situation that caused the alarm, if no one acknowledges the alarm on the workstation, it won't re-alarm if the situation reoccurs.

Is there any fix for this, short of having someone clear it at the workstation? (We have personnel issues, to say the least).  Also, does anyone know what "clamining" the alarm in Delta V Mobile actually does?

Thank you so much, Cynthia

  • Alarm.NALM :=1;

    maybe more info needed, take your whatever bit that triggered the alarm like say the HI_ACT out of the AI block into the enable of a resettable timer that goes into a TP, the output of the timer done shoud reset itself, when timer expires then action block writes the Alarm.NALM:=1;

    this way you can set that if in alarm and remains in alarm how often the it will realarm
