Basic LabVIEW Data
Acquisition Concepts
This chapter explains key concepts in understanding how data acquisition
works with LabVIEW. Before you start building your data acquisition
(DAQ) application, you should know some of the following basic
LabVIEW DAQ concepts:
• Location of Common DAQ Examples
• Locating the Data Acquisition VIs in LabVIEW
• DAQ VI Organization
• VI Parameter Conventions
• Common DAQ VI Parameters
• Default and Current Value Conventions
• Error Handling
• Channel, Port, and Counter Addressing
• Limit Settings
• Data Organization for Analog Applications
If you do not already understand basic programming concepts in
LabVIEW, refer to the
LabVIEW User Manual
or the
G Programming
Reference Manual
for help with programming in LabVIEW.

The easiest way to locate a particular DAQ example is to
run the DAQ Solution Wizard. You can access the DAQ Solution Wizard
by clicking on the
DAQ Solution Wizard
button when you first launch
LabVIEW, or by selecting
DAQ Solution Wizard
from the
File
menu in
LabVIEW.
The DAQ examples address many common applications involving
data acquisition in LabVIEW. You can find these examples in
