Getting Started with the
NI PXI-7811R
This document explains how to set up the National Instruments PXI-7811R
device.
Introduction
The PXI-7811R is an R Series reconfigurable I/O (RIO) device with
160 digital I/O (DIO) lines.
Traditional digital I/O devices have a fixed functionality provided by an
application-specific integrated circuit (ASIC), but the PXI-7811R has a
field-programmable gate array (FPGA) that allows you to define device
functionality and timing.
You can use the LabVIEW FPGA Module to graphically design the
PXI-7811R timing and functionality without having to learn a low-level
programming language or a hardware description language (HDL)
traditionally used for FPGA design. With the LabVIEW FPGA Module,
you create or download a custom virtual instrument (VI) to the FPGA.
You can reconfigure the PXI-7811R device with a new VI at any time.
You can use the LabVIEW Real-Time Module to communicate and control
the PXI-7811R device while performing additional tasks, such as real-time
floating-point processing and data logging.
Note
If you are using LabVIEW but not the LabVIEW FPGA Module, you can create VIs
that run in LabVIEW to control existing FPGA VIs, but you cannot create new FPGA VIs.
The PXI-7811R device has Flash memory that you can use to store VIs.
You can configure VIs to load to the FPGA and to run when the device
powers up.
