Returns the interchangeability warnings associated with the IVI session. This node 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.
To guarantee that this node only returns those interchangeability warnings generated after calling the niSwitch Reset Interchange Check node, clear the list of interchangeability warnings by repeatedly calling this node until no interchangeability warnings are returned. If you are not interested in the content of those warnings, call the niSwitch Clear Interchange Warnings node.
Control that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node.
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.
Default: No error
Indicator that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node and used for all subsequent NI-SWITCH calls.
Error information.
The node produces this output according to standard error behavior.

Next interchange warning for the IVI session. If there are no interchangeability warnings remaining for the session, this output returns an empty string.
NI-SWITCH performs interchangeability checking when the Interchange Check property is set to TRUE.
The node returns an empty string for interchange warning if no interchangeability warnings remain for the session.
In general, NI-SWITCH generates interchangeability warnings when a property that affects the behavior of the switch is in a state that you did not specify.
