Building Programmable Automation Controllers with LabVIEW
FPGA电路焊接
Overview
Programmable Automation Controllers (PACs) are gaining acceptance within the
industrial control market as the ideal solution for applications that require highly integrated
analog and digital I/O, floating-point processing, and amless connectivity to multiple
processing nodes. National Instruments offers a variety of PAC solutions powered by one
common software development environment, NI LabVIEW. With LabVIEW, you can build
custom I/O interfaces for industrial applications using add-on software, such as the NI
LabVIEW FPGA Module.
With the LabVIEW FPGA Module and reconfigurable I/O (RIO) hardware, National
Instruments delivers an intuitive, accessible solution for incorporating the flexibility and
customizability of FPGA technology into industrial PAC systems. You can define the logic
embedded in FPGA chips across the family of RIO hardware targets without knowing low-
level hardware description languages (HDLs) or board-level hardware design details, as well
as quickly define hardware 绍兴香炉峰for ultrahigh-speed control, customized timing and
synchronization, low-level signal processing, and custom I/O with analog, digital, and
counters within a single device. You also can integrate your custom NI RIO hardware with
image acquisition and analysis, motion control, and industrial protocols, such as CAN and
RS232, to rapidly prototype and implement a complete PAC system.

Introduction
You can u graphical programming in LabVIEW and the LabVIEW FPGA Module to
configure the FPGA (field-programmable gate array) on NI RIO devices. RIO technology, the
merging of LabVIEW graphical programming with FPGAs on NI RIO hardware, provides a
flexible platform for creating sophisticated measurement and control systems that you could

An FPGA is a chip that consists of many unconfigured logic gates. Unlike the fixed,
vendor-defined functionality of an ASIC (application-specific integrated circuit) chip, you can
configure and reconfigure the logic on FPGAs for your specific application. FPGAs are ud
in applications where either the cost of developing and fabricating an ASIC is prohibitive, or
the hardware must be reconfigured after being placed into rvice. The flexible, software-
programmable architecture of FPGAs offer benefits such as high-performance execution of
custom algorithms, preci ios11越狱timing and synchronization, rapid decision making, and
simultaneous execution of parallel tasks. Today, FPGAs appear in such devices as instruments,
consumer electronics, automobiles, aircraft, copy machines, and application-specific
computer hardware. While FPGAs are often ud in industrial control products, FPGA
functionality has not previously been made accessible to industrial control engineers.
Defining FPGAs has historically required experti using HDL programming or complex
design tools ud more by hardware design engineers than by control engineers.
With the LabVIEW FPGA Module and NI RIO三年级英语下册课本 hardware, you now can u LabVIEW, a
high-level graphical development environment designed specifically for measurement and
control applications, to create PACs that have the customization, flexibility, and high-
performance of FPGAs. Becau the LabVIEW FPGA Module configures custom circuitry in
hardware, your system can process and generate synchronized砂仁的作用与功效 analog and digital signals
rapidly and deterministically. Figure 1 illustrates many of the NI RIO devices that you can
configure using the LabVIEW FPGA Module.

Historically, programming FPGAs has been limited to engineers who have in-depth
knowledge of VHDL or other low-level design tools, which require overcoming a very steep
learning curve. With the LabVIEW 马来酸氨氯地平片FPGA Module, NI has opened FPGA technology to a
