About AVEVA Historian licensing

You must have a license to run AVEVA Historian. Your license allows for a certain number of tags on your server. For example, you may have a 5,000-tag license. As you add tags, the License Server activates a portion of the license, in 50-tag increments. For example, if you initially add 120 tags to AVEVA Historian, License Server activates three 50-tag increments.

If you have used the full number of tags allowed by your license, you can add an incremental license (for example, to add another 25,000 tags) to your existing license.

If your AVEVA Historian server is an Enterprise Server that you are also using as a replication (tier-2) server for another Historian, all of the replicated tags stored on this server count against this server’s license.

Your AVEVA Historian license does not limit the number of these types of tags on your server:

• Locally replicated tags (that is, the original tag is on the same server)

• Auto-summary tags

If your license expires, or you don’t yet have a license, you can still:

• Continue acquiring and storing tags indefinitely

• Retrieve values for up to 32 tags for the last 7 days
