Currently, there are two methods to 'shift' archives:
1. "Archive_AutoArchiveFileRoot" set to blank
2. "Archive_OverwriteDataOnAutoShiftFailure" enabled
Neither method shifts to dynamic archives. We have three sites that merged PI servers, thus ha...

Safeguard against multiple analyses writing to the same PI Point
Safeguard against multiple analyses writing to the same PI Point. Currently it is possible to configure more than one analysis to write to the same PI point. This is a problem since it often goes undetected until someone looks at the data and sees...
I find myself making analytics on child elements which by themselves have limited value, but are needed to get rollup analyses to work. This adds complexity to the design of AF. Two ideas would improve this:
1) Count # of attributes that meet a c...
Let Start Trigger severity set the EventFrame severity
Currently the Severity of the EF is set on the template. The severity of a start trigger allows to create child events.
I want to have the ability to have the severity of the start trigger set the severity of the generated EventFrame. In that way...
Event Frames Scalability - For Customer Advisory Lab Scenarios
#of assets (in this specific scenario): 500-1000
EF Count: Generation rate of 25,000/day peak, would like to historize for 1+y = 9,000,000 events+
Attributes: 5-10 attributes/event (static or PI Point)
Flat Hierarchy
Queries: EF are alarms or ...
Keeping old events that have been manually worked on in case of Recalculation/Backfill
Case 1.
There are some EFs that should be acknowledged and commented by equipment owners. In Pharma World, these comments qualify as GxP and shall not be deleted. Whereas Event Frames generated by analysis can sometimes due to data coming late or ...
Option to write EF template attribute result back into a PI-tag
Creating a possibility to populate PI-tag's based on the Events. These PI-tag's can be used in reports/displays. Generating batch, daily, hourly, shift and other "event" driven values and store them in a specific PI-tags would very easy and may re...
Currently, interpolation is a function that allows users to estimate values from 1 column to another. However, in industry, it is very possible to have to interpolate across multiple columns. Having the option is cleaner an more accura...
In AF, right clicking an attribute reveals an options called "change display UOM", but it's not doing what is expected.
To change the displayed UOMs (if, for instance, we want to see "km/h" instead of "m/h" in PI Vision), we need to do the follow...
PI AF Linked Tables used for Time-Series Data with OOO events
As AF Table Lookup Data Reference is configured with a time column in order to support cashing, edits of the following types to the table data will not be picked up by AF Clients:
1- Update the value of an Existing record/Event
2- Add a ne...
