Data Archive

To account for the different historical implementations of Daylight Saving Time in different regions, a localhost.tz file is added to the %piserver%\dat directory after installation. As an installer of PI Data Archive, I would like the localhost.t...

Currently, PI SMT will only allow archives to be reprocessed according to it's original type. User would like to be able to choose whether to reprocess the archives from fixed to dynamic or vice versa.

As a user I want to be able to collect, store and analyze quality information associated with real-time events and assets. This feature will allow the user to determine the trustworthiness of the data when decisions are made. Note: This was previ...

All methods exposed through AF SDK and other Developer Technologies are "fire and forget". Please add methods, at least for time series data, which return when the data has been processed. A write operation that returns when data has been process...

Currently, if you want to store predictions for 1 day, 2 days, 3 days, etc. into the future, you must create a different PI tag for each distance into the future. Future data tags should support 2 timestamps: the timestamp that the predicted valu...

PI DA Server should allow for more flexibility in terms of the format of archived data. A big advantage would be if PI could archive two timestamps per event. One timestamp will come from whatever the data source is (PI Interfaces, fiels devices, ...
