CD Bode VI
Owning Palette: Frequency Response VIs
Installed With: Control Design and Simulation Module
Produces the Bode magnitude and Bode phase plots of the system model on an XY graph. The data types you wire to the State-Space Model and Frequency Info inputs determine the polymorphic instance to use.
This VI converts state-space and zero-pole-gain models to transfer function models before calculating the frequency response.
Use the pull-down menu to select an instance of this VI.

CD Bode (Frequency Range, State-Space)
Phase Graph Reference is a reference to the Bode Phase plot on an XY graph. Phase Graph Reference automatically configures the x-scale, y-scale, and legend properties. If you want to use the default settings or customize the settings for these properties, do not wire a value to this input. | |||||||||||||
Magnitude Graph Reference is a reference to the Bode Magnitude plot on an XY graph. Magnitude Graph Reference automatically configures the x-scale, y-scale, and legend properties. If you want to use the default settings or customize the settings for these properties, do not wire a value to this input. | |||||||||||||
State-Space Model contains a mathematical representation of and information about the system of which this VI produces Bode plots. | |||||||||||||
Frequency Range contains the frequency information of the model.
| |||||||||||||
Magnitude Scale specifies how to scale the magnitude of the frequency response.
| |||||||||||||
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.
| |||||||||||||
Plots Index specifies which input and which output to plot. If you do not specify the input #, this VI plots all the inputs.
| |||||||||||||
Bode Magnitude is a plot on an XY graph that plots the linear or decibel magnitude of the given model against a set of frequencies. The Plots Index array determines the plots on this XY graph. | |||||||||||||
Bode Phase is a plot on an XY graph that plots the phase (in degrees) of the model against a set of frequency values. The Plots Index array determines the plots on this XY graph. | |||||||||||||
Bode Data returns information about the Bode plot.
To access the Bode Data, use the CD Get Frequency Response Data VI.
| |||||||||||||
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.
