Wait Until Done (G Dataflow)

Version:
    Last Modified: March 3, 2017

    Waits until the acquisitions and/or generations corresponding to sessions are done, or until the node returns a timeout error.

    This node is most useful for finite data operations that you want to complete within a certain time. This node is a blocking node that periodically checks the operation status. This node returns control to the program if the operation completes successfully, or if an error occurs, including a timeout error.

    connector_pane_image
    datatype_icon

    sessions in

    Array of session references that are being synchronized.

    Obtain session references from an instrument driver by using the Get Session Reference node for that driver.

    datatype_icon

    timeout

    The amount of time that Wait Until Done waits for the sessions to complete. This value is expressed in seconds. If this parameter is exceeded, Wait Until Done returns an error.

    Default: 10

    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

    sessions out

    Array of session references passed to the next node.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
