Export Attribute Configuration (Export Attribute Configuration Buffer) (G Dataflow)

Version:
    Last Modified: July 24, 2019

    Exports a session configuration to a buffer.

    Note

    You can export and import supported configurations only between NI-FGEN devices with identical bus types, model numbers, and channel counts, as well as the same number of initialized channels.

    This node verifies that the session configuration is valid. If the configuration is invalid, this node returns an error.

    connector_pane_image
    datatype_icon

    session in

    Handle that identifies the NI-FGEN instrument session as previously allocated by Initialize With Channels .

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input 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.

    Default: No error

    datatype_icon

    session out

    Reference to the NI-FGEN instrument session to pass to the next node in the program.

    datatype_icon

    buffer

    Byte array that contains the exported configuration.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Supported Configurations

    You can export and import the following between NI-FGEN sessions:

    • Attribute configurations
    • Arbitrary waveforms

    Requirements for Exporting and Importing Arbitrary Waveforms

    Arbitrary waveforms you export and import between sessions using this node must meet the following criteria:

    • All waveforms in the exporting session are created from files, other than HWS files, using the Create Waveform node
    • The full file path of the file containing the arbitrary waveform still exists at the time of import
    • All waveforms are defined using handles rather than names
    • All waveforms are complete—none are streamed or incrementally written

    You can set the device mode with the Configure Output Mode node.

    Channel Mapping Behavior

    When exporting and importing configurations between NI-FGEN sessions that were initialized with different channels using the channel name input to the Initialize With Channels node, the configuration of the exporting channel is mapped to the importing channel.

    For example, if your entry for channel name is 0 for the exporting session and 1 for the importing session, the configuration exported from channel 0 is imported into channel 1.

    Note

    This node will return an error if the total number of channels initialized for the exporting session is not equal to the total number of channels initialized for the importing session.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
