CD Write Model to File VI
Owning Palette: Model Construction VIs
Installed With: Control Design and Simulation Module
Creates a new file or appends to an existing file, writes the specified number of records to the file, then closes the file and checks for errors. Each record is a model. The data type you wire to the State-Space Model input determines the polymorphic instance to use.
Use the pull-down menu to select an instance of this VI.

CD Write Model to File (State-Space)
 | File Path (dialog if empty) specifies the file path to the model location. | ||||||
 | State-Space Model contains a mathematical representation of and information about a system that you want to write to a file. | ||||||
 | If append to file? is TRUE, the VI appends data to an existing file. If append to file? is FALSE (default), the VI replaces data in an existing file. If there is no existing file, the VI creates a new file. | ||||||
 | 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 exception control to treat what is normally an error as no error or to treat a warning as an error.
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.
| ||||||
 | new file path returns the path to the file. | ||||||
 | Offset after Write (Records) is the location in the datalog file where the VI writes the next record. | ||||||
 | 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.

CD Write Model to File (Transfer Function)
| File Path (dialog if empty) specifies the file path to the model location. | ||||||
| Transfer Function Model contains a mathematical representation of and information about the system that you want to write to a file. | ||||||
| If append to file? is TRUE, the VI appends data to an existing file. If append to file? is FALSE (default), the VI replaces data in an existing file. If there is no existing file, the VI creates a new file. | ||||||

CD Write Model to File (Zero-Pole-Gain)
