Setting Up Hardware

LabVIEW is a graphical programming environment used by

millions of engineers and scientists to develop sophisticated

measurement, test, and control systems

LabVIEW can integrate with wide variety of hardware

ni.com/training

devices

In this course, you will interact with DAQ, GPIB, and serial

hardware

DAQ Hardware DAQ Device

Most DAQ devices have four standard elements: analog

input, analog output, digital I/O, and counters

You can transfer the signal you measure with the DAQ

device to the computer through a variety of different bus

ni.com/training

structures

13


14/33

DAQ Hardware Analog Input

The process of measuring an analog signal and transferring

the measurement to a computer for analysis, display, or

storage

An analog signal is a signal that varies continuously

ni.com/training

Analog input most commonly measures voltage or current

14


15/33

DAQ Hardware Analog Output

The process of generating analog signals from your computer

Performing digital-to-analog (D/A)

conversions generates analog output

ni.com/training

are voltage and current

To perform a voltage or current

output, a compatible device must be

installed that can generate that

type of signal

15


16/33

DAQ Hardware Digital I/O

Digital signals:

Electrical signals that transfer digital data (on/off, high/low, 1/0)using a wire

Used to control or measure digital or finite state devices, such

ni.com/training

Used to transfer data

program devices

communicate between devices

Use digital signals as clocks or triggers tocontrol or synchronize other measurements

16


17/33

DAQ Hardware Counters

Acounter is a digital timing device typically used for event

counting, frequency measurement, period measurement,

position measurement, and pulse generation

A counter has a fixed number it can count to as determined

ni.com/training

by the resolution of the counter

For example, a 24-bit counter

can count to:

2(Counter Resolution) 1 = 224 1 = 16,777,215

B. Using DAQ Software Configuration

Configure and test your DAQ device using the Measurement

& Automation Explorer (MAX)

ni.com/training18

Exercise 1-1

Concept: Measurement and Automation Explorer

GOAL

Use MAX to examine, configure, and test a DAQ device.

C. Instrument Control

Use software on a PC to control an instrument over an

instrument control bus

Mix and match instruments from various categories

ni.com/training

,communication protocols to use


23/33

C. Instrument Control

Benefits of Instrument Control

Automate processes

Save time

ni.com/training

Ease of use

Many types of instruments available


24/33

D. GPIBGPIB (general purpose

interface bus) is astandard interface for

communication between

instruments and controllers

from various vendors

ni.com/training24


25/33

GPIB

The bus supports one system controller, usually a computer,

and up to 14 additional instruments

Controller:

Defines the communication links

ni.com/training

Responds to devices that request service

Sends GPIB commands

Passes/receives control of the bus

25


26/33

E. Serial Port Communication

Serial communication

Transmits data between a computer and a peripheraldevice, such as a programmable instrument or anothercomputer

ni.com/training

ses a transm tter to sen ata one t at a t me over asingle communication line to a receiver

Best method when data transfer rates are low, or you musttransfer data over long distances

Most computers have one or more serial ports, so you donot need any extra hardware other than a cable

26


27/33

F. Using Instrument Control Software

Interface Drivers: Instrument interfaces such as GPIB

include a set of drivers for the interface

Configuration: Use MAX to configure the interface

ni.com/training27


28/33

Exercise 1-2

Concept: GPIB Configuration with MAX

GOAL

Learn to configure the NI Instrument Simulator and use MAX

to examine the GPIB interface settings, detect instruments,and communicate with an instrument.
