Run this VI as a background task. If logging is enabled, this VI logs simulation data. This VI can log either all samples continuously, or only the last N time steps worth of data. Set the Last Run control to True on the last iteration of the loop containing this VI to flush the remaining data in the log data buffer to file.

	Simulation Data in specifies unique information about the model.
	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. 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.
	Last Run specifies to send no more data to the Base Rate Loop. Set this control to True on the last iteration of the loop containing this VI.
	Simulation Data out returns unique information about the model DLL.
	logfile refnum (Deprecated) contains the file format type and file refnum for the data log file. This output is no longer relevant for the Driver VI. It is only a placeholder for SIT 3.0.x Driver VIs.
	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.
