I want to share Delete PI Data Archive tag values tool.
Some customers have requested to delete events for specific time span and specific values.
I've created sample tool by AFSDK.
Code is in GitHub.
This tool can delete tag's events.
You can specify followings.
PI Tags name
All Events/ Specific Events (Manual entery of value)
Start Time/End Time
If you have interesting, please check this tool.
Also remember that deleting PI tag values effects performance for PI Data Archive.
So I recommend to delete a few events/tags.
