	address space specifies the address space without requiring VISA Map Address to be called. The following table lists the valid entries for specifying address space. Value Description VXI, VME, and GPIB-VXI VXI/VME A16 (1) 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 In 8, VISA In 16, VISA In 32, and VISA In 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.
	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.
	value contains the data read from address space.
	error out contains error information. This output provides standard error out functionality.
