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

| PXI |
PXI Memory Allocations (9)

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 read from.
The type of resource determines how offset specifies the offset.- INSTR Specific—The offset specified in the VISA In 8, VISA In 16, and VISA In 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 VXI/VME A16, offset specifies the offset from the logical address base address of the specified VXI device. If address space specifies VXI/VME A24, A32, or A64, offset specifies the offset from the base address of the VXI device's memory space allocated by the VXI Resource Manager within VXI/VME A24, A32 or A64 space.
- MEMACC Specific—For a MEMACC Resource, offset specifies an absolute address.

value contains the data to write to address 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 occurred 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.
 |
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
|
 |
code is the error or warning code. The default is 0.
If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
|
|
 |
VISA resource name out is a copy of the VISA resource name that VISA functions return.
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 front panel indicator and select Explain Error from the shortcut menu for more information about the error.
 |
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
|
 |
code is the error or warning code.
If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
