Backplane (BACKPLANE) Resource Events

BACKPLANE is a Windows-only feature.

In the following tables, AP = Access Privilege, RO - Read Only, and RW = Read/Write.

VI_EVENT_TRIG

Notification that a trigger interrupt was received from the backplane. For VISA, the only triggers that can

be sensed are VXI hardware triggers on the assertion edge (SYNC and ON trigger protocols only).

Event Attribute	Attribute Value	Description	AP	Data Type	Range
VI_ATTR_EVENT_TYPE	0x3FFF4010UL	Unique logical identifier of the event.	RO	ViEventType	VI_EVENT_TRIG
VI_ATTR_RECV_TRIG_ID	0x3FFF4012UL	The identifier of the triggering mechanism on which the specified trigger event was received.	RO	ViInt16	VI_TRIG_TTL0 to VI_TRIG_TTL11 VI_TRIG_TTL0 through VI_TRIG_TTL7 apply to both VXI and PXI trigger lines. VI_TRIG_TTL8 through apply only to PXI trigger lines.; VI_TRIG_ECL0 to VI_TRIG_ECL5; VI_TRIG_STAR_SLOT1 to VI_TRIG_STAR_SLOT12

VI_EVENT_VXI_VME_SYSFAIL

Notification that the VXI/VME SYSFAIL* line has been asserted.

Event Attribute		Attribute Value	Description		AP		Data Type		Range
