Maps a specified memory space. The memory space that is mapped is dependent on the type of interface specified by VISA resource name and the address space parameter. After the window is mapped, VISA keeps track of the window that is mapped. This dictates that VISA can only map one window for each VISA session.

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. | ||||||
![]() |
map base contains the offset (in bytes) of the memory to be mapped.
INSTR Specific Notice that map base specified in the VISA Map Address operation 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 VI_A16_SPACE, then map base specifies the offset from the logical address base address of the specified VXI device. If address space specifies VI_A24_SPACE or VI_A32_SPACE, then map base 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. MEMACC Specific For a MEMACC Resource, map base specifies an absolute address. |

map size contains the amount of memory to map. | ||||||

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. | ||||||
![]() |
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.
