Use the aaHistClientSingleValueEntry control at runtime

Use the aaHistClientSingleValueEntry control to manually add single data value for a tag in the AVEVA Historian database. To add a data value for a tag:

• You must log in to the historian with administrative privileges.

• The tag must currently exist in the database.

Values are inserted into the AVEVA Historian’s history blocks. Therefore, you can retrieve them using the same views and tables as data that is stored automatically by the AVEVA Historian.
