IviDigitizer Get Next Interchange Warning (G Dataflow)

Last Modified: October 24, 2017

Returns the interchangeability warnings associated with the IVI session. It retrieves and clears the oldest instance in which the class driver recorded an interchangeability warning. Interchangeability warnings indicate that using your application with a different instrument might cause different behavior. You use this node to retrieve interchangeability warnings. The driver performs interchangeability checking when the IviDigitizer>>Inherent IVI Settings>>User Options>>Interchange Check property is set to TRUE. The node returns an empty string in the Interchange Warning parameter if no interchangeability warnings remain for the session. In general, the instrument driver generates interchangeability warnings when a property that affects the behavior of the instrument is in a state that you did not specify.

interchange warning

Returns the next interchange warning for the IVI session. If there are no interchange warnings, this parameter returns an empty string.

datatype_icon

instrument handle out

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

Default: None

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.

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

Default: None
