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 VI to retrieve interchangeability warnings.
The class driver performs interchangeability checking when the IviUpconverter>>Inherent IVI Attributes>>User Options>>Interchange Check property is set to TRUE and you call IviUpconverter Wait Until Ready.
The node returns an empty string in the Interchange Warning parameter if no interchangeability warnings remain for the session.
Interchangeability checking examines the properties in a capability group only if you specify a value for at least one property within that group. In general, the class driver generates interchangeability warnings when it encounters one of the following conditions:
The instrument handle that you obtain from the IviUpconverter Initialize or IviUpconverter Initialize With Options Node. The handle identifies a particular instrument session.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
|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.
Default: No error
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
Returns the next interchange warning for the IVI session. If there are no interchange warnings, this parameter returns an empty string.
