Acknowledging all alarms from specific area

   Hi guys,

   Does anybody know if it is possible to acknowledge all alarms from one specific area at once? For example, when a input signal comes to DeltaV, all alarms for the specific area should be acknowledged.

Thanks,

Samuel Bandeira

  Before addressing the "how", let's discuss the "why". If you are acknowledging all alarms for an area, which could contain multiple unit equipment and hundreds of devices, is the area itself undergoing a shutdown or something that would allow you to perform a wholesale acknowledgment rather than a intentional system by system corrective action of the alarm conditions on a running process? If so, then a better question would be how to proactively disable all alarms for an area, to prevent erroneous alarms in the first place.
  There's no out of the box way to do what you are requesting, and it could probably be scripted, but I think an assessment of why this function would be required should be considered.

  Thanks Youssef, I appreciate your advise. The reason I asked is that we are in a migration project and in the actual logic, there is a DI, which acknowledges all alarms for a certain area. I'll take a look with customer to understand the real need of this kind of logic.

  I see. Since it is a migration, I suspect you are dealing with a legacy system that pre-dates the ISA 18.2 recommendations on alarms, so a single button that acknowledges everything in an area may not have been vetted in this context. I would refer to this recommendation when discussing with the customer.
