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.

Inputs/Outputs

  • cvsrn.png VISA resource name —

    VISA resource name specifies the resource to be opened. The VISA resource name control also specifies the session and class.

  • ci16.png mode —

    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.
  • cu32.png status ID —

    status ID is the status value to be presented during an interrupt acknowledge cycle.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ivsrn.png VISA resource name out —

    VISA resource name out is a copy of the VISA resource name that VISA functions return.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    • Note VISA Assert Interrupt Signal does not accept VISA sessions of class Instr. The VISA session must be of class VXI/GPIB-VXI Backplane or VXI Servant.
