Get Installed Device Attribute (I32) (G Dataflow)

Version:
    Last Modified: September 16, 2017

    Returns the specified integer attribute.

    connector_pane_image
    datatype_icon

    session in

    Session handle created by niModinst Open Installed Devices Session.

    datatype_icon

    index in

    Zero-based index that specifies the device for which you want the attribute.

    Valid Range

    device countdevice count niModinst Open Installed Devices Session
    datatype_icon

    attribute ID

    ID of the integer attribute you want to query.

    Table 1. Valid Values
    Value Attribute
    Slot Number The chassis slot in which the device is installed. This attribute can only be queried for PXI modules installed in a chassis that has been properly identified in MAX.
    Chassis Number The number of the chassis in which the device is installed. This attribute can only be queried for PXI modules installed in a chassis that has been properly identified in MAX.
    Bus Number The bus on which the device or module has been enumerated.
    Socket Number The socket number on which the device has been enumerated.
    spd-note-note
    Note  
    • The bus number and socket number can be used to form a VISA resource string for the device, of the form PXIn::x::INSTR, where n is the bus number and x is the socket number. For example, for bus number 2 and socket number 13, use PXI2::13::INSTR.
    • Traditional NI-DAQ devices do not support the Bus Number and Socket Number attributes.

    error in

    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.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    session out

    Session handle identical to the session in handle.

    datatype_icon

    index out

    Zero-based index identical to the index in value.

    datatype_icon

    attribute value

    Value of the requested attribute.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
