SIT Initialize Model VI

Owning Palette: Model Interface VIs

Requires: Simulation Interface Toolkit

Loads the model DLL, initializes the model, registers the model with the SIT Server, and sets the final time. This VI returns the model time step and the number of input ports and output ports needed. You must call this VI before taking any model steps.

Use the SIT Finalize Model VI to unload the model DLL when you finish executing the model.

	Buffer Sizes specifies the sizes of the buffers that the SIT Server uses to communicate with real-time (RT) targets. number of signals specifies the maximum number of model signals that you can probe. The default value is 50. circular buffer size specifies the depth of the buffer. The default value is 1000. num data points specifies the width of the buffer. The default value is 100. The total width of all the signals you probe in one time step must be less than or equal to num data points. The width of a signal is equal to the number of elements in that signal. For example, the width of a 2×2 array is 4. Note  num data points has a large impact on the performance of the SIT Server. To ensure that the LabVIEW Simulation Interface Toolkit does not allocate more buffer space than necessary, set num data points to the lowest possible value.
	path to model DLL specifies the path to the model DLL on the RT target.
	stop time specifies the simulated time in seconds after which the model DLL terminates. If you wire -1 to the stop time, the model DLL does not terminate until you stop the VI. The default value is -1.
	time step returns the simulated time increment, in seconds, for each step of the model DLL during execution.
	Server On? is TRUE if you can start the SIT Server. Server On? is FALSE if you cannot start the SIT Server. The default value is TRUE.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	base period returns the base time step of the simulation, in microseconds.
	Simulation Data out returns unique information about the model DLL.
	number of model inputs returns the number of inputs to the model DLL.
	number of model outputs returns the number of outputs from the model DLL.
	error out contains error information. This output provides standard error out functionality.
	Signal Info returns information about the signals in the model DLL that you can probe. You must create a mapping for a signal in order to probe that signal. Index returns the index number of the signal. ID returns a unique string that identifies the signal. Block Name returns the path of the signal, for example, sinewave/Sine Wave. Port Number returns the port number of the signal. Signal Name returns the user-defined name of the signal. Data Type returns the data type of the signal. Dimensions returns the dimensions of the signal.
	Param Info returns information about the parameters in the model DLL that you can manipulate. You must create a mapping for a parameter in order to manipulate that parameter. paramidx returns the index of the parameter. ID returns a unique string that identifies the parameter. paramname returns the path of the parameter, for example, sinewave/Sine Wave/Amplitude. datatype returns the data type of the parameter. Dimensions returns the dimensions of the parameter. value returns the current value of the parameter.
