Which command is used to establish a connection to a Historian Server using the ActiveEvent control?

The command used to establish a connection to a Historian Server using the ActiveEvent control is "InitializeEx("ComputerName")". This command is specifically designed to initialize a connection to the Historian Server by providing the server's name, thereby allowing the ActiveEvent control to start interacting with the data stored on that server. It's essential because establishing the connection is the first step before any operations or data retrieval can occur.

The other commands do not pertain to the ActiveEvent control's standard methods for connecting to a Historian Server, which emphasizes that "InitializeEx" is the correct and formally recognized approach for this task.
