Issue
An Enterprise Central has two Enterprise Servers, both connected to External Log storage as pictured below.
How can the EC access trend logs in both External Log storage locations when it is only connected to one of them?

Environment
- Building Operation Enterprise Central
- Building Operation Enterprise Server
- Building Operation Automation Server Premium (AS-P)
Cause
It is only possible to specify a connection to one External Log storage location in the EC
Resolution
When a user needs to access trend data from a specific log located in, for example, an AS-P while the Workstation is connected to the EC, the following process occurs:
- The EC contacts the specified External Log storage for the log data using the trend log ID.
- If the trend log ID is not found in the specified External Log storage, the EC then contacts the Enterprise Server (ES) associated with the AS-P to request the log data.
- The ES connects to the External Log storage specified within it and retrieves the log data using the trend log ID.
- The ES delivers the log data to the EC, which in turn delivers it to the Workstation for access.
This process ensures that the EC effectively manages connectivity to External Log storage systems and retrieves the required trend data for users.
