ParameterDescription
ConversionContains the following options:
  • Resulting data type—Specifies the data type that you want to convert to from the dynamic data type.
  • Floating point numbers (double)—Formats numeric values as double-precision, floating-point numbers, including the values in arrays.
  • Boolean (TRUE and FALSE)—Formats numeric values as Boolean values, including the values in arrays.
  • Channel—Specifies the channel from which you want to retrieve the data.
Input SignalDisplays the input signal. If you wire data to the Express VI and run it, Input Signal displays real data. If you close and reopen the Express VI, Input Signal displays sample data until you run the VI again.
Result PreviewDisplays a preview of the measurement. The Result 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, Result Preview displays real data. If you close and reopen the Express VI, Result Preview displays sample data until you run the VI again. If the cutoff frequency values are invalid, Result Preview does not display valid data.

Block Diagram Inputs

ParameterDescription
ChannelSpecifies the channel from which you want to retrieve the data. The value you wire to this input overrides the value you set in the configuration dialog box.
Dynamic Data TypeContains the input signal formatted as dynamic data.

Block Diagram Outputs

ParameterDescription
ArrayReturns the output signal converted into an array of numeric values. You also can configure the Convert from Dynamic Data Express VI to return the following outputs:
  • Scalar—Returns the output signal converted into a numeric value.
  • Waveform—Returns the output signal converted into a waveform.
  • Array of Waveform—Returns the output signal converted into a 1D array of waveform data.
