E. Serial PortCommunication

F. Using Instrument ControlSoftware

Setting Up Hardware LabVIEW is a graphical programming environment used bymillions of engineers and scientists to develop sophisticatedmeasurement, test, and control systems

LabVIEW can integrate with wide variety of hardwaredevices

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

DAQ Hardware DAQ Device Most DAQ devices have four standard elements: analoginput, analog output, digital I/O, and counters

You can transfer the signal you measure with the DAQdevice to the computer through a variety of different busstructures

13 ni.com/training

DAQ Hardware Analog InputThe process of measuring an analog signal and transferringthe measurement to a computer for analysis, display, orstorage An analog signal is a signal that varies continuously Analog input most commonly measures voltage or current

14

ni.com/training

DAQ Hardware Analog OutputThe process of generating analog signals from your computer Performing digital-to-analog (D/A)conversions generates analog output

The available analog output typesare voltage and current

To perform a voltage or currentoutput, a compatible device must beinstalled that can generate thattype of signal

15 ni.com/training

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, suchas switches and LEDs

Used to transfer data program devices communicate between devices

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

16

ni.com/training

DAQ Hardware Counters A counter is a digital timing device typically used for eventcounting, frequency measurement, period measurement,position measurement, and pulse generation

A counter has a fixed number it can count to as determinedby the resolution of the counter

For example, a 24-bit countercan count to:2(Counter Resolution) 1 = 224 1 = 16,777,215

17 ni.com/training

B. Using DAQ Software Configuration Configure and test your DAQ device using the Measurement& Automation Explorer (MAX)

18

4ni.com/training

Simulating a DAQ Device Using NI-DAQmx simulated devices, you can try NI productsin your application without the hardware

With NI-DAQmx simulated devices, you also can export aphysical device configuration onto a system that does nothave the physical device installed

19GOAL

Exercise 1-1Concept: Measurement and Automation Explorer

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

C. Instrument Control Use software on a PC to control an instrument over aninstrument control bus

Mix and match instruments from various categories Understand the properties of the instrument, such as thecommunication protocols to use

ni.com/training

C. Instrument ControlBenefits of Instrument Control Automate processes Save time One platform for multiple tasks Ease of use Many types of instruments available

ni.com/training

D. GPIBGPIB (general purposeinterface bus) is astandard interface forcommunication betweeninstruments and controllersfrom various vendors

24

5ni.com/training

GPIB The bus supports one system controller, usually a computer,and up to 14 additional instruments

Controller: Defines the communication links Responds to devices that request service Sends GPIB commands Passes/receives control of the bus

25 ni.com/training

E. Serial Port CommunicationSerial communication Transmits data between a computer and a peripheraldevice, such as a programmable instrument or anothercomputer Uses a transmitter to send data one bit at a time 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

ni.com/training

F. Using Instrument Control Software Interface Drivers: Instrument interfaces such as GPIBinclude a set of drivers for the interface

Configuration: Use MAX to configure the interface

27GOAL

Exercise 1-2Concept: GPIB Configuration with MAX

Learn to configure the NI Instrument Simulator and use MAXto examine the GPIB interface settings, detect instruments,and communicate with an instrument.
