Requires: LabVIEW DataFinder Toolkit

Connects a DataFinder or a DataFinder federation with the specified connection parameters.

If you leave the VI inputs open, the VI tries to connect the local "My DataFinder" DataFinder and returns a reference to the DataFinder connection. If you specify a server name and a DataFinder name, the VI connects to a DataFinder Server Edition, which might be activated on another computer, and provides a reference to the DataFinder connection. The input terminals of the Open Server VI contain the same information that is saved with the registered DataFinder connection. If you want to open a DataFinder with specific timeouts, for example, you can either change the connection settings of the registered DataFinder permanently, or you can use the VI with the associated inputs to use various settings temporarily.

If you use a DataFinder server from the DataFinder Server Edition as a DataFinder server, you need at least Version 2.0 of the DataFinder Server Edition to execute a search. To configure a local DataFinder server with the property nodes and invoke nodes, you need at least Version 2.1 of the DataFinder Server Edition.

DataFinder

	DataFinder name (My DataFinder) is the name of the DataFinder on the other computer.
	server name (localhost) is the name of the computer where the DataFinder server is located.
	connection timeout in s specifies how long it takes to connect the two computers. If the specified time elapses, an error message appears.
	query timeout in s specifies the maximum length of time that the client waits for the results of a query. If the specified time elapses, an error message appears.
	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
	DataFinder reference out is the reference to the open DataFinder.
	error out contains error information. This output provides standard error out functionality.

Federation

port (2809) specifies the port the DataFinder listens to.

DataFinder name is the name of the DataFinder on the other computer.

server name (localhost) is the name of the computer where the DataFinder server is located.

user name is the user name for the authentication. The format is username@domain.

password is the password for the authentication.

error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

authentication mode specifies the authentication mode. You can use the following values:

0	No security (Default)
1	User name/password
2	Single sign on

DataFinder reference out is the reference to the open DataFinder.

error out contains error information. This output provides standard error out functionality.
