Opens a data connection you specify in URL.

	URL identifies the data source to read or data target to write. URLs begin with the name of the protocol you want to use to read or write the data, such as psp, dstp, opc, ftp, http, and file. You also can wire a shared variable control to this terminal.
	mode specifies the mode of the data connection. Select a value based on the operation you want to perform through the data connection: read, write, read/write, buffered read, buffered read/write. The default value is 0, for read. Buffering applies when you use the DataSocket Read function to read data a server writes. Buffering is not available when you use front panel DataSocket data binding to read data. Buffering is available for front panel data binding through the Shared Variable Engine if you bind controls to shared variables with buffering enabled on the Variable page of the Shared Variable Properties dialog box. Note  To minimize data loss, you also should buffer the data on the server. 0 Read (default) 1 Write 2 ReadWrite 3 BufferedRead 4 BufferedReadWrite
	ms timeout specifies the time in milliseconds to wait until LabVIEW establishes a connection. The default is 10,000 ms (10 seconds). If you specify –1, the function waits indefinitely. If you specify 0, LabVIEW does not attempt to establish a connection and returns error 56.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	connection id uniquely identifies the data connection.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
