CD Draw Transfer Function Equation VI
Owning Palette: Model Construction VIs
Installed With: Control Design and Simulation Module
Displays the transfer function equation of the model. The data type you wire to the State-Space Model input determines the polymorphic instance to use.

CD Draw Transfer Function Equation (State-Space)
 | Format Coefficients specifies how to format the resulting equation. You can enter any of the LabVIEW format specifier syntax elements. The default value is %#_g, which removes trailing zeros and specifies that LabVIEW uses fractional or scientific notation depending on the exponent of the number. | ||||||||
 | display format specifies the format in which this VI displays the equation.
| ||||||||
 | State-Space Model contains a mathematical representation of and information about the system for which this VI draws an equation. | ||||||||
 | Output (row) specifies the index number of the output row from which to draw the transfer function matrix. The index is zero-based. The default is –1, which draws all outputs. | ||||||||
| Input (column) specifies the index number of the input column from which to draw the transfer function matrix. The index is zero-based. The default is –1, which draws all inputs. | ||||||||
 | 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.
| ||||||||
 | Origin specifies the upper-left position of the equation this VI draws.
| ||||||||
| Function Name specifies the function this VI draws. For example, if you enter H, this VI displays H(s)= for continuous equations and H(z)= for discrete equations. | ||||||||
 | Equation draws a picture of the model equation this VI defines. | ||||||||
 | Draw Area Size specifies the size of the area in the picture control this VI uses to draw the model equation. | ||||||||
 | 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.
