    source width

    The width of the source data.

    Name Value Description
    8-bit 1 The source width is 8 bits long.
    16-bit 2 The source width is 16 bits long.
    32-bit 4 The source width is 32 bits long.
    64-bit 8 The source width is 64 bits long.

    Default: 16-bit

    datatype_icon

    source space

    Address space of the data to be moved.

    Name Value Description
    VXI/VME A16 1 VXI/VME A16
    VXI/VME A24 2 VXI/VME A24
    VXI/VME A32 3 VXI/VME A32
    VXI/VME A64 4 VXI/VME A64
    PXI Memory Allocations 9 PXI Memory Allocations
    PXI Configuration 10 PXI Configuration
    PXI BAR0 - PXI BAR5 11-16 PXI BAR address spaces

    Default: VXI/VME A16

    datatype_icon

    session in

    The resource to be used.

    datatype_icon

    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

    source offset

    The offset, in bytes, of the device to read from.

    This terminal is the offset address relative to the device's allocated address base for the corresponding specified address space. For example, if source space specifies VXI/VME A16, source offset specifies the offset from the logical address base address of the VXI device specified.

    If source space specifies VXI/VME A24, A32, or A64, source offset specifies the offset from the base address of the VXI device's memory space allocated by the VXI Resource Manager within VXI A24 or A32.

    Default: 0

    datatype_icon

    length

    Number of elements to move.

    datatype_icon

    destination offset

    The offset, in bytes, of the destination device.

    Default: 0

    datatype_icon

    destination space

    Address space of the destination.

    Name Value Description
    VXI/VME A16 1 VXI/VME A16
    VXI/VME A24 2 VXI/VME A24
    VXI/VME A32 3 VXI/VME A32
    VXI/VME A64 4 VXI/VME A64
    PXI Memory Allocation 9 Physical, locally allocated address space.
    PXI Configuration 10 The PXI configuration address space.
    PXI BAR0 - PXI BAR5 11-16 PXI memory or I/O address spaces 0 through 5.

    Default: VXI/VME A16

    datatype_icon

    destination width

    Width of the destination data.

    Name Value Description
    8-bit 1 The destination data is 8 bits wide.
    16-bit 2 The destination data is 16 bits wide.
    32-bit 4 The destination data is 32 bits wide.
    64-bit 8 The destination data is 64 bits wide.

    Default: 16-bit

    datatype_icon

    session out

    The resource to which a VISA session is opened.

    This output also includes the class for the session, which matches that of session in.

    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
