Hi. I have seen the PI Tag that references the PV.ALM parameter from DeltaV in several projects in different pharmaceutical sites.
That tag brings the information of the alarm like Tag description, Alarm status (Active/Unacknowledged, Inactive/Acknowledged, etc.), Alarm Limit, etc.
How can I take advantage of that tag in PI Notifications to notify that an alarm is active? The information is already in the tag as a string coming from DeltaV. I will be surprised if PI doesn't use it to notify that there is an alarm. What uses have you seen of this PV.ALM tag before?
The tag is in the following format, lets say as example: 111-PDI-2222/PV.ALM for the alarms of a PDI.
In DeltaV it is used to present an alarm state in the screen. Not sure how it is used in PI. If I cannot use it, I will have to create at least 2 new tags in PI to reference PV.CV and Alarm Limit and then configure the PI Notification to compare PV.CV with the limit instead of taking the information from the available PV.ALM tag.
Thanks,
Janette
