2. Under Collectives and Servers, select the Historian server
whose data you want to check.
3. Under System Management Tools, select Operation >
Licensing.
4. Expand your Historian server item.
5. Go to Resources >
PointSourceLimit.PINotifications-InternalUse.
The Amount Used property indicates the number of licenses
used for the notifications: it is 7 points per notification.
NOTE
The numbers provided for PINotifications in Total, Amount
Used, and Amount Left are multiplied by 7 against those set in
the FactoryTalk Administration Console. It is because each
notification uses 7 points from the Rockwell pool.
For example, if you set the limit for notifications to 50 in the
FactoryTalk Administration Console, the Total number of
allocated licenses in the System Management Tools will equal
350.
Similarly, if you enable 50 notifications, the Amount Used value
will equal 350.
