2. Internship name :
Virtual Automation
Based Online Summer Internship Program
Intern at :
National Instruments Innovation Centre
Duration : 6 weeks
3. Introduction to
National Instruments :
NI, formerly National Instruments Corporation,
is an American multinational company with
international operation. Headquartered in
Austin, Texas, it is a producer of automated
test equipment and
virtual instrumentation software. Common
applications include data
acquisition, instrument control and machine
vision.
4. LabVIEW overview :
What is LabVIEW:
LabVIEW (Laboratory Virtual Instrument Engineering Workbench),
created by National Instruments (www.ni.com) is a graphical
programming language that uses icons instead of lines of text to create
applications.
LabVIEW programs/codes are called Virtual Instruments, or VIs
for short.
LabVIEW is used for Data acquisition, signal Processing
(Analysis), and hardware control – a typical instrument
configuration based on Labview.

6. LabVIEW environment
A VI has three main parts :
1. Front panel : Interacts with the user
2. Block diagram : Contains the code
3. Controls Palette : Contains the controls and indicators you use to
create the front panel.
4. Terminals : Ports through which data passes between the block
diagram and the front panel, and between nodes. Terminal is any
point to which you can attached a wire to pass data.
7. Front Panel :
When you open a new or existing VI, the front panel window of the
VI appears. The front panel window is the user interface for the
VI. Figure 1 shows an example of a front panel window.
8. Block Diagram :
Block diagram objects include terminals, subVIs, functions,
constants, structures, and wires, which transfer data among other
block diagram objects.After you create the front panel window, you
add code using graphical representations of functions to control the
front panel objects. The block diagram window contains this
graphical source code.
9. Control palette :
The Controls palette contains the controls and indicators you use to
create the front panel. You access the Controls palette from the
front panel window by selecting View»Controls Palette or by right
clicking on any empty space in the front panel window. The
Controls palette is broken into various categories; you can expose
some or all of these categories to suit your needs. Figure shows a
Controls palette with all of the categories exposed and the Modern
category expanded.
11. Terminals :
There are different terminals:
• Control and indicator terminals
• Node terminals
• Constant terminals.
• Specialized terminals on various structures.
Terminals are entry and exit ports that exchange information between
the front panel and block diagram. They are analogous to parameters
and constants in text-based programming languages. Types of terminals
include control or indicator terminals and node terminals. Control and
indicator terminals belong to front panel controls and indicators. Data
points you enter into the front panel controls (a and b in the previous
front panel) enter the block diagram through the control terminals.
12. LabVIEW Programming Concept :
LabVIEW follows Data-Flow programming .
The process to determine the execution of program is called Arbitrary-
Interleaving .
During compilation the VI compiler constructs a wired table .
LabVIEW functions are polymorphic.
LabVIEW is not an interpreted language it is compiled behind the
scenes by LabVIEW’s execution engine.
LabVIEW constructs a wire table for the VI .
This wire table identifies elements in the block diagram that have inputs
needed for that element to run .
A LabVIEW program is executed by pressing the arrow or the Run
button located in the palette along the top of the window
13. Applications of LabVIEW :
Machine monitoring and control :LabVIEW Real-Time module helps
in preparing powerful machine monitoring and control applications.
Research and Analysis : Scientist and Researchers use it biomedical
,aerospace energy industries etc .
Control Design : Real world data can be compared with theoretical
data .
14. Benefits :
Extensive Interface - Even people with limited coding experience
can write programs and deploy solutions in reduced time interval.It
also includes An interface to .NET framework assembly .
Code Reuse and Platform independent -The G-code is independent
of the operating system .
Parallel Processing- Easy to code programs with multiple
tasksperformed in parallel by multithreading .
