Are configuration changes that lead to new History Blocks limited in frequency?

Configuration changes that lead to new History Blocks can indeed occur at any time. This flexibility allows users to adjust settings or modify configurations according to their operational needs without being bound to specific time intervals. In many data processing systems, including the AVEVA Historian, the capability to implement changes promptly is critical for maintaining optimal data management and operational efficiency.

While some systems may include limits to prevent excessive changes that might disrupt data integrity or system performance, in the case of configuration changes leading to new History Blocks, there is generally no restriction on their timing. This allows for a responsive approach to data management, ensuring that historians can adapt quickly to new data requirements or operational adjustments.

The other options suggest specific limitations or conditions regarding the timing of these changes, which does not accurately reflect the system's operational flexibility.
