FPGA Interface User Guide, for information about the FPGA Interface 
functions.
You can use Interactive Front Panel Communication to communicate 
directly with the VI running on the FPGA. You can use Programmatic 
FPGA Interface Communication to programmatically control and 
communicate with FPGA VIs from host VIs.
Use the FPGA Interface functions when you target LabVIEW for Windows 
or an RT target to create host VIs that wait for interrupts and control the 
FPGA by reading and writing the FPGA VI running on the R Series device.
Note
If you use the R Series device without the FPGA Module, you can use the Download 
VI or Attributes to Flash Memory utility available by selecting Start»Program Files»
National Instruments»NI-RIO
 to download precomplied FPGA VIs to the Flash memory 
of the R Series device. This utility is installed by the NI-RIO CD. You also can use the 
utility to configure the analog input mode, to synchronize the clock on the R Series device 
to the PXI clock (for NI PXI-783xR only), and to configure when the VI loads from Flash 
memory. 
LabVIEW Real-Time Module
The LabVIEW Real-Time Module extends the LabVIEW development 
environment to deliver deterministic, real-time performance.
You can write host VIs that run in Windows or on RT targets to 
communicate with FPGA VIs that run on the NI 783xR. You can develop 
real-time VIs with LabVIEW and the LabVIEW Real-Time Module, and 
then download the VIs to run on a hardware target with a real-time 
operating system. The LabVIEW Real-Time Module allows you to use the 
NI 783xR in RT Series PXI systems being controlled in real time by a VI.
The NI 783xR is designed as a single-point AI, AO, and DIO complement 
to the LabVIEW Real-Time Module. Refer to the LabVIEW Real-Time 
Module User Manual
 and the LabVIEW Help, available by selecting 
Help»VI, Function, & How-To Help, for more information about the 
LabVIEW Real-Time Module.
