National Instruments NI 783xR Manuel D’Utilisation

This section explains reconfigurable I/O and describes how to use the  
LabVIEW FPGA Module to build high-level functions in hardware.

Refer to Chapter 2, 

, for descriptions 

of the I/O resources on the NI 783xR.

The NI 783xR is based on a reconfigurable FPGA core surrounded by fixed 
I/O resources for analog and digital input and output. You can configure 
the behavior of the reconfigurable FPGA to match the requirements of the 
measurement and control system. You can implement this user-defined 
behavior as an FPGA VI to create an application-specific I/O device.

Flexible functionality allows the NI 783xR to match individual application 
requirements and to mimic the functionality of fixed I/O devices. For 
example, you can configure an R Series device in one application for three 
32-bit quadrature encoders and then reconfigure the R Series device in 
another application for eight 16-bit event counters.

You also can use the R Series device with the LabVIEW Real-Time Module 
in timing and triggering applications, such as control and 
hardware-in-the-loop (HIL) simulations. For example, you can configure 
the R Series device for a single timed loop in one application and then 
reconfigure the device in another application for four independent timed 
loops with separate I/O resources.
