Copies an array of 64-bit data from device memory to local memory.
The resource to be used.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
The offset, in bytes, of the location to read from.
This function accepts a 32- or 64-bit unsigned integer as input. The type of resource determines how offset specifies the offset.
The number of data items to move.
The address space.
The following table lists the valid entries for specifying address space:
Name | Value | Description |
---|---|---|
VXI/VME A16 | 1 | The A16 address space of a VXI or VME device. |
VXI/VME A24 | 2 | The A24 address space of a VXI or VME device. |
VXI/VME A32 | 3 | The A32 address space of a VXI or VME device. |
VXI/VME A64 | 4 | The A64 address space of a VXI or VME device. |
PXI Memory Allocations | 9 | A physical, locally allocated address space. |
PXI Configuration | 10 | The PXI configuration address space. |
PXI BAR0 - PXI BAR5 | 11-16 | PXI memory or I/O address space 0 through 5. |
Default: VXI/VME A16
The resource to which a VISA session is opened.
This output also includes the class for the session, which matches that of session in.
Error information.
