Licensing and output streams

The Licensing tab on the Administration page provides information about the number of output streams used and which views use the output streams.

An output stream is a PI tag (data point) that is published to a target or only referenced in a view. A unique output stream is a distinct PI tag published in one or more views.

Your specific software package and licensing agreement determines the maximum number of unique output streams you can have at one time.

For example, assume that the PI Integrator is configured with three views: ProcLab1, TestPrd, and Fieldoutput. ProcLab1 uses 20 output streams (15 unique output streams, 5 non-unique output streams), TestPrd uses two unique output streams, and Fieldoutput uses 22 output streams (2 unique output streams, 20 non-unique output streams). Output Streams by View list displays the three views with the total output streams used in each view. The following totals are displayed:

• Unique Output Streams Consumed displays 19 output streams.

• Remaining Output Streams displays the balance of the available output streams. The total available streams depends on the maximum allowed with your license.

Increase available output streams

If the number of output streams is insufficient to meet your needs, you can upgrade to a version with a higher maximum. For more information on the available maximum output stream counts, speak with your AVEVA account manager.
