CD Remove IO from Model VI

Owning Palette: Model Reduction VIs

Installed With: Control Design and Simulation Module

Selects the inputs, outputs and/or states that you want to remove from the original system model. If you want to keep inputs, outputs, or states from the original system model, use the CD Select IO from Model VI. The data type you wire to the State-Space Model input determines the polymorphic instance to use.

CD Remove IO from State-Space Model

States specifies the index number of the states you want to remove from the State-Space Model. The index is zero-based. If you wire a value of –1 to this parameter, this VI removes all model states.
State-Space Model contains a mathematical representation of and information about the system of which this VI removes the states, inputs and/or outputs from the resulting model.
Inputs specifies the index numbers of inputs you want to remove from the system model. The index is zero-based. If you wire a value of –1 to this parameter, this VI removes all model inputs.
Outputs specifies the index numbers of outputs you want to remove from the system model. The index is zero-based. If you wire a value of –1 to this parameter, this VI removes all model outputs.
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.
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.
Reduced Model is the resulting system model without the states, inputs, or outputs you specified to remove. To access and modify the data in the model, use the Model Information 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.

CD Remove IO from Transfer Function Model

Transfer Function Model contains a mathematical representation of and information about the system in which this VI removes the inputs and/or outputs from the resulting model.
Inputs specifies the index numbers of inputs you want to remove from the system model. The index is zero-based. If you wire a value of –1 to this parameter, this VI removes all model inputs.
Outputs specifies the index numbers of outputs you want to remove from the system model. The index is zero-based. If you wire a value of –1 to this parameter, this VI removes all model outputs.

CD Remove IO from Zero-Pole-Gain Model

Zero-Pole-Gain Model contains a mathematical representation of and information about the system in which this VI removes the inputs and/or outputs from the resulting model.
