Writes a 32-bit block of data to the specified address space and offset.

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

VXI/VME A24 (2)

VXI/VME A32 (3)

VXI/VME A64 (4)
PXI PXI Memory Allocations (9)

PXI Configuration (10)

PXI BAR0 (11) to PXI BAR5 (16)
VISA resource name specifies the resource to be opened. The VISA resource name control also specifies the session and class.
offset is the offset, in bytes, of the device to read from. offset accepts a 32- or 64-bit unsigned integer as input. The type of resource determines how offset specifies the offset.
  • INSTR Specific—The offset specified in the VISA Out 8, VISA Out 16, VISA Out 32, and VISA Out 64 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 node runs. This input provides standard error in functionality.
VISA resource name out is a copy of the VISA resource name that VISA functions return.
error out contains error information. This output provides standard error out functionality.
