Where To Go From Here

Where to Start with the NI PXI-7831R
PXI-7831R. A reference to this VI running on the FPGA is passed to
the subsequent nodes on the block diagram. These nodes can interact
with the VI running on the FPGA by reading and writing its indicators
and controls to control the execution of the FPGA VI. After the While
Loop on the 1 RIO Board (Host) VI block diagram finishes execution,
the Close FPGA VI Reference function stops the execution of the VI
on the FPGA. Refer to the context help for the 1 RIO Board (Host) VI
for more information about the operation of this VI.
13. The Default 7831R (FPGA) VI that runs on the PXI-7831R FPGA
provides much more functionality than the 1 RIO Board (Host) VI
actually uses. The Default 7831R (FPGA) VI provides a timed loop
synchronizing all of the I/O available on the PXI-7831R (8 AI, 8 AO,
and 96 DIO). The Default 7831R (FPGA) VI offers a variety of
different timing modes that allow it to run off of its own internal loop
timer, or to synchronize its operation with other devices in the system.
To view the Default 7831R (FPGA) VI, double-click the Open FPGA
VI Reference function on the 1 RIO Board (Host) VI block diagram
using the selection tool. This opens the front panel for the Default
7831R (FPGA) VI. Refer to the context help for the Default 7831R
(FPGA) VI for more information about this VI. You can also look at
the block diagram code to see how this VI operates.
14. Close the 1 RIO Board (Host) VI and the Default 7831R (FPGA) VI,
and exit LabVIEW when you are done. For more information using
FPGA VIs like the Default 7831R (FPGA) VI, refer to the LabVIEW
FPGA Module User Manual.
Refer to the following documentation for information about the
LabVIEW FPGA Module, RIO hardware, and VIs needed for your
application.
• LabVIEW FPGA Module Release Notes—This document describes the
software installation and other known software issues.
• LabVIEW FPGA Module User Manual—This manual describes the
LabVIEW FPGA Module software and techniques for building
applications in LabVIEW with the FPGA Module. Even if you do not
have the FPGA module installed, NI recommends that you read
Chapter 4, Communicating with FPGA VIs.
• NI PXI-7831R User Manual—This manual describes the electrical and
mechanical aspects of the NI PXI-7831R device and contains
information concerning its operation and programming.
• LabVIEW Help—This help describes the VIs and function reference
information.
