What is the default behavior of a Historian Server when an event occurs without any configured actions?

The default behavior of a Historian Server when an event occurs without any configured actions is to log it for future reference. This function allows for events to be captured and stored in the historian database, enabling users to analyze historical data or events later. By logging these events, the system ensures that important information is retained, which can be critical for troubleshooting, performance evaluation, or compliance audits.

In this context, logging serves as a foundational capability of the historian system, facilitating a comprehensive understanding of the system's operation and events over time, even when no specific actions are defined in response to those events. This approach helps preserve data integrity and allows users to review past occurrences, aiding in informed decision-making based on historical data trends.
