Creates a hierarchy of timing sources based on the names you enter in timing source names.

The hierarchy determines the order in which the timing sources start. The parent timing source does not start until after the timing sources in hierarchy name start. Use this VI when you have timing sources that have signal dependencies, such as DAQ counters routed to drive analog input connections. In such a case, the counter timing source acts as the parent.

	replace (F) replaces any timing source you entered in timing source names if a timing source by that name already exists in the hierarchy of timing sources.
	hierarchy name is the name of the timing source hierarchy you want to create.
	parent is the valid timing source you want to start after the all the timing sources in hierarchy name start.
	timing source names is an array of names of the timing sources you want to add to the timing source hierarchy. If replace is TRUE, the new timing source replaces any timing source with the same name that already exists in the timing source hierarchy. These timing sources start before the timing source you enter in parent.
	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.
	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.
