In VXI, for example, this can be done with either a VXI signal or a VXI interrupt. On certain bus types, statusID may be ignored.

Details  

VISA resource name specifies the resource to be opened. The VISA resource name control also specifies the session and class.
mode specifies how to assert the interrupt. This input accepts the following values.

–1VXI Signal—Send the notification using a VXI signal.
0Assigned Method—Use the notification method assigned to the local device.
1–7VXI/VME IRQ1–VXI/VME IRQ7—Send the interrupt through the specified VXI/VME IRQ line. This uses the standard VXI/VME ROAK (release on acknowledge) interrupt mechanism rather than the older VME RORA (release on register access) mechanism.
status ID is the status value to be presented during an interrupt acknowledge cycle.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
VISA resource name out is a copy of the VISA resource name that VISA functions return.
error out contains error information. This output provides standard error out functionality.
