If in the current session you have already connected to a Historian server, you can select it in the combobox below to auto-fill the Host Input.

!Important :
Because the Historian Connector can connect to any server regardless if it is a local server or not, you need to specify a SQL Server account type to connect to the Runtime Database.

Host

This is the address of the SQL Server instance you need to access for the Wonderware Historian “Runtime” database. Possible values are :

• (local) or localhost : local server
• <NetBIOSName> : server named with a NetBIOS name
• <IPv4Address> : server accessible through a IP v4 address
• <IPv6Address> : server accessible through a IP v6 address
• <server address>\<instance name> : connect to a specific instance. For SQL Express, it may be necessary to use <server address>\SQLEXPRESS
• <server address>,1433 : 1433 is the default port for SQL Server, but can be changed like this
  

*Be aware that when searching for a server instance, Alpana waits for a response. If the server instance doesn’t respond, there is a rather long timeout.
