When are application server tags created in Historian?

Application server tags in AVEVA Historian are created during the process of configuring objects for historization and then deploying them. This step involves defining which data points within the application will be monitored and stored in the historian database.

When you configure an object for historization, you specify the relevant parameters, such as data type and how often the data should be collected. Once these objects are deployed, the historian recognizes them and creates the necessary tags in the system to facilitate data collection. This systematic approach ensures that only relevant and required data points are created based on the specific needs of the application, which helps optimize database performance and data management.

Other options do not align with this logical flow: simply launching the application does not trigger tag creation without specific configurations, and users manually adding tags does not reflect the intended automation of the historian system. Additionally, a system reset would not typically result in the generation of new tags, as tags are meant to persist through resets unless deliberately removed.
