Digital Signal Subset (G Dataflow)

Version:
    Last Modified: May 9, 2017

    Returns a subset of the specified digital data you can use to plot the extracted signals individually or in subgroups on a graph.

    datatype_icon

    digital waveform

    The digital waveform from which you want to extract signals.

    This input appears when you wire a waveform to digital data. If you wire digital data to digital waveform, this input changes to digital data.

    datatype_icon

    digital data

    Set of digital data from which you want to extract signals .

    This input appears when you wire digital data to digital waveform. If you wire a waveform to digital data, this input changes to digital waveform.

    datatype_icon

    signals

    1D array of numbers that represent the signals that you want to extract.

    Errors with Signals Input

    signals
    datatype_icon

    error in

    Error conditions that occur before this node runs. Unlike most nodes, this node runs normally even if an error occurs before this node runs.

    Default: no error

    datatype_icon

    digital subset (Waveform)

    The requested subset of digital waveform.

    This output appears when you wire a waveform to digital data. If you wire digital data to digital waveform, this output changes to digital subset (Digital Data).

    datatype_icon

    digital subset (Digital Data)

    The requested subset of digital data.

    This output appears when you wire digital data to digital waveform. If you wire a waveform to digital data, this output changes to digital subset (Waveform).

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Where This Node Can Run:

    Desktop OS: Windows
