For historized object attributes to have their tags created in Historian, which of the following must be true?

For historized object attributes to have their tags successfully created in the Historian, it is essential for the Historian to be operational and for the object to be deployed. When the Historian is running, it can actively process data and manage the creation of tags associated with the attributes of the object. Deployment of the object ensures that the attributes are recognized by the system and ready to be historized, enabling data collection and storage.

In this context, the conditions outlined in the other statements hinder the creation process. For instance, if the Historian is paused or not running, it cannot perform any data activities, including tag creation. Additionally, if the object is not deployed, the Historian cannot recognize the attributes associated with that object, preventing tag creation. Therefore, operability and correct deployment are crucial for effective functioning within the Historian environment.
