IviUpconverter Get Next Coercion Record (G Dataflow)

    Obtains the coercion information associated with the IVI session. It retrieves and clears the oldest instance in which the specific driver coerced a value you specified to another value. If you set the IviUpconverter>>Inherent IVI Attributes>>User Options>>Record Value Coercions property to TRUE, the specific driver keeps a list of all coercions it makes on ViInt32 or ViReal64 values you pass to instrument driver nodes. You use this node to retrieve information from that list. The node returns an empty string in the Coercion Record parameter if no coercion records remain for the session.

    instrument handle

    The instrument handle that you obtain from the IviUpconverter Initialize or IviUpconverter Initialize With Options Node. The handle identifies a particular instrument session.

    Default: None

    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

    instrument handle out

    The instrument handle that you obtain from the IviUpconverter Initialize or IviUpconverter Initialize With Options VI. The handle identifies a particular instrument session. Default Value: None

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    coercion record

    Returns the next coercion record for the IVI session. If there are no coercion records, the node returns an empty string.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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