Can the Active Event be triggered immediately after connecting to a Historian Server?

In the context of the AVEVA Historian Server, the correct understanding is that an Active Event cannot be triggered immediately upon connection to the Historian Server. This is because the system requires a certain initialization process after establishing a connection. During this time, the server may need to validate the connection, retrieve relevant historical data, and ensure that all necessary configurations and parameters are correctly set.

Typically, when a connection is established, the server needs to be fully operational, and all event monitoring mechanisms must be in place and properly initialized before any Active Events can be triggered. This ensures that the events are processed correctly and that the data integrity is maintained.

Other options imply immediate activation or conditions that do not align with the operational requirements of the Historian Server. Therefore, it is not just an instantaneous action but rather a process that must be completed for the Active Event mechanisms to function appropriately.
