Last Modified: June 1, 2017

Reads and writes values to controls or indicators in the FPGA VI on the FPGA target.


FPGA Host Interface in

Reference to an FPGA VI.


error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error


FPGA Host Interface out

Reference to an FPGA VI


error out

Error information. The node produces this output according to standard error behavior.



The element of the FPGA VI that you want to read or write.

By default, this element is configured to read. To write this element, right-click the element and select Change to Read/Write from the shortcut menu.

To access more elements, resize the node.

Where This Node Can Run:
