Synchronizes the start of Timed Loops or Timed Sequence structures you enter in timed structure names by adding the names to the synchronization group you specify in synchronization group name.

All timed structures in a synchronization group wait until all the structures are ready to execute.

Example

	clear (F), if TRUE, removes all timed structures from synchronization group name before adding the timed structures in timed structure names to the group. Set clear (F) to TRUE to remove any timed structures that do not correspond to a Timed Loop. The default is FALSE.
	replace (T) replaces the timed structures in synchronization group name with the timed structures you enter in timed structure names. If replace is FALSE and the timing source is a member of another hierarchy, the VI returns an error.
	synchronization group name is the name for the group of timed structures that you want to synchronize.
	timeout ms (10000) is the amount of time a timed structure waits on other members of the synchronization group to arrive to the synchronization point. If any of the timed structures in the group do not arrive in time, the timed structure returns an error. The default is 10,000 ms. A value of –1 indicates to wait indefinitely.
	timed structure names specifies the names of the timed structures you want to synchronize. By default, the VI deletes the timed structure from its current group and adds it to the group you specify in synchronization group name. If you set replace (T) to FALSE and a timed structure you specify in timed structure names is a member of another group, the VI returns an error to indicate that it could not add the timed structure to the synchronization group.
	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.
	timed structures names out returns the names of all timed structures in the group after LabVIEW adds the names to the synchronization group you specify.
	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.
