    default value

    Value this node uses to fill in extra samples if the specified sets of digital data do not have the same number of samples.

    Name Value Description
    0 0 Force Down
    1 1 Force Up
    Z 2 Force Z
    L 3 Compare Low
    H 4 Compare High
    X 5 Compare Don't Care
    T 6 Compare Invalid
    V 7 Compare Valid

    Default: 0

    datatype_icon

    digital waveform (high bits)

    First set of data in the digital waveform.

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

    datatype_icon

    digital data (high bits)

    The first set of data.

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

    datatype_icon

    digital waveform (low bits)

    Set of data to append to digital waveform (high bits). This node ignores the start time of digital waveform (low bits) and uses the start time in digital waveform (high bits).

    This input appears when you wire a waveform to digital data (high bits). If you wire digital data to digital waveform (high bits), this input changes to digital data (low bits).

    datatype_icon

    digital data (low bits)

    Set of data to append to digital data (high bits). The number of samples in this set of data does not have to match the number of samples in digital data (high bits). However, if the number of signals do not match, error out returns an error.

    This input appears when you wire digital data to digital waveform (high bits). If you wire a waveform to digital data (high bits), this input changes to digital waveform (low bits).

    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 waveform out

    Waveform that results from appending digital waveform (low bits) to digital waveform (high bits). This output matches the compression of the input.

    This output appears when you wire a waveform to digital data (high bits). If you wire digital data to digital waveform (high bits), this output changes to digital data out.

    datatype_icon

    digital data out

    Digital data that results from appending digital data (low bits) to digital data (high bits).

    This output appears when you wire digital data to digital waveform (high bits). If you wire a waveform to digital data (high bits), this output changes to digital waveform out.

    datatype_icon

    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.
