Moves a block of data from device memory to local memory in accesses of 8-bits. The VISA Move In 8 function uses the specified address space to read in 8-bits of data from the specified offset. You do not need to call the VISA Map Address function before you call this function.

address space specifies the address space to map.
The following table lists the valid entries for specifying address space:

VISA resource name specifies the resource to be opened. This control also specifies the session and class. Refer to VISA Resource Name Control for more information. | ||||||

offset is the offset (in bytes) of the device to write to.
INSTR Specific
The offset specified in the VISA Move Out 8, VISA Move Out 16, and VISA Move Out 32 operations for an INSTR Resource is the offset address relative to the device's allocated address base for the corresponding address space that was specified.For example, if address space specifies A16 SPACE, then offset specifies the offset from the logical address base address of the VXI device specified. If address space specifies A24 or A32 SPACE, 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 SPACE. The count specified in the VISA Move Out XX operations for an INSTR Resource is the number of data items (of the size corresponding to the operation) to move, beginning at the specified offset. Therefore, offset + count*size cannot exceed the amount of memory exported by the device in the given space. MEMACC Specific For a MEMACC Resource, offset specifies an absolute address. The count specified in the VISA Move Out XX operations for a MEMACC Resource is the number of data items (of the size corresponding to the operation) to move, beginning at the specified offset. Therefore, offset + count*size cannot exceed the total amount of memory available in the given space. |

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

dup VISA resource name is a copy of the VISA resource name that is passed out of the VISA functions. Refer to VISA Resource Name Control for more information. | ||||||
![]() |
data is the 8 bits of data being moved. | ||||||
![]() |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
