Interrupt Event (PxiSession)



Keysight.Visa Namespace > PxiSession Class : Interrupt Event
Occurs when a PXI interrupt is received from the device.
Syntax
'Declaration
 

Public Event Interrupt As EventHandler(Of PxiInterruptEventArgs)
'Usage
 

Dim instance As PxiSession
Dim handler As EventHandler(Of PxiInterruptEventArgs)
 
AddHandler instance.Interrupt, handler
public event EventHandler<PxiInterruptEventArgs> Interrupt
public:
event EventHandler<PxiInterruptEventArgs^>^ Interrupt
Event Data

The event handler receives an argument of type PxiInterruptEventArgs containing data related to this event. The following PxiInterruptEventArgs properties provide information specific to this event.

PropertyDescription
CustomEventType A value that uniquely identifies an implementation-specific event type. (Inherited from Ivi.Visa.VisaEventArgs)
Data The first register that was read in the successful interrupt detection sequence.  
EventType The VISA.NET standard event type. (Inherited from Ivi.Visa.VisaEventArgs)
Sequence The index of the interrupt sequence that detected the interrupt condition.  
Remarks

Multiple event handlers may be registered for this event.

When a calling program registers an event handler, it is possible that the event handler might be called before the call to register the event handler returns. In this case, the event handlers registered for an event are executed before the return of the event handler registration.

Client programs should either use the event-related methods VisaSession.DisableEvent, VisaSession.DiscardEvents, VisaSession.EnableEvent, and VisaSession.WaitOnEvent (any overload) with the appropriate eventType, -or- the .NET events which are defined individually for each event stype in the ession class to which they apply. If a calling program uses both mechanisms at the same time, it will receive the event twice, once for each mechanism.

Requirements
