Dialog Box Options

ParameterDescription
ConversionContains the following options:
  • Input data type—Specifies the data type that you want to convert to the dynamic data type.
  • Floating point numbers (double)—Specifies that numeric values are double-precision, floating-point numbers.
  • Boolean (TRUE and FALSE)—Specifies that numeric values are Boolean values.
InputsDisplays the input signal. If you wire data to the Express VI and run it, Inputs displays real data. If you close and reopen the Express VI, Inputs displays sample data until you run the VI again.
Results PreviewDisplays a preview of the measurement. The Results Preview plot indicates the value of the selected measurement with a dotted line. If you wire data to the Express VI and run the VI, Results Preview displays real data. If you close and reopen the Express VI, Results Preview displays sample data until you run the VI again. If the cutoff frequency values are invalid, Results Preview does not display valid data.
Start TimeContains the following options:
  • Zero—Sets the t0 of the input signal to zero.
  • Now—Sets the t0 of the input signal to the current system time.

Block Diagram Inputs

ParameterDescription
ArrayContains the input waveform or array of numbers or Boolean values. You also can configure the Convert to Dynamic Data Express VI to accept the following outputs:
  • 2D Array—Contains the input signal formatted as a 2D array of numbers.
  • Waveform—Contains the input signal formatted as a waveform.
  • Array of Waveforms—Contains the input signal formatted as a 2D array of waveforms.
  • Double—Contains the input signal formatted as a double-precision, floating-point number.
  • Boolean—Contains the input signal formatted as a single Boolean value.

Block Diagram Outputs

ParameterDescription
Dynamic Data TypeReturns a dynamic data type with the values you entered in the Array input.

Example
