How frequently can History Blocks be created based on configuration changes?

History Blocks in the AVEVA Historian are designed to capture and store data changes efficiently. They can be created daily or even more frequently, depending on the threshold limits set within the configuration. This allows for a more responsive data collection approach where History Blocks are generated as soon as key parameters are met, such as significant data changes outside of normal operational ranges or specific user-defined criteria.

This flexibility ensures that data is logged without unnecessary delays, allowing for timely access to real-time information and compliance with operational requirements. Other options, such as limitations to weekly, monthly, or specific endpoints of data collection periods, would not offer the adaptability that the AVEVA Historian system is designed to provide. Therefore, the ability to create History Blocks based on the actual data change thresholds enhances the efficiency and effectiveness of data management within the historian environment.
