LabVIEW is one of the software development systems first introduced by National Instrument Inc. This software development system used in many applications such as industrial applications, experiment applications, educational measurement applications, and automation applications. LabVIEW is available in the form of a graphical programming type, which supports many textual programming languages like C, MATLAB programming, and Math script. LabVIEW system has a large number of functional features for data visualizations, designing, and numerical analysis applications. Many areas like mathematics, controlling, signal processing system, system and data identifications, and simulation applications designed based on the LabVIEW system. It also supports third-party communications with hardware systems like OPC, GPIB, and Modbus, etc.
In this section, we will discuss the LabVIEW Environment,
LabVIEW Environment is an ecosystem where the LabVIEW software development system exists. This environment consists of different elements that are used for program development within the LabVIEW system. This Environment also comprises many tools that help to develop LabVIEW applications.
Now let me explain about LabVIEW Environment tools,
Templates and project samples:
This is one of the important tools available in the LabVIEW environment, it consists of many common templates used for starting projects with already existing projects which give information like how the project may work and need any customizations for all type of business applications.
Finding example tool:
This component consists of many code snippets that can help you to develop many methodologies that describe the project. Example finder tools can be used or customized as per your project requirement.
The debugging tool is an essential part of any project development. This enables users to speedy the debugging of the program. Elements included are Probes method, breaking points, Single-step method, and high executions.
This Source control tool is mainly used for configuration management purposes. It helps a large number of groups can work together on the development of project applications.
LabVIEW network tools enable the users to download the toolkits to perform a specific task. Some of these tools are provided by the mother company of LabVIEW named National Instruments and other its child companies (or you can call them as its partners)

Let us know the importance of LabVIEW,
A LabVIEW application is mainly designed on two methods those are Controls and Indicators. Controls work as an Input and also ‘control’ the data while accessing LabVIEW application. Indicators work as an output or 'Indicate' the data, graphics, and information. Let us see how these two methods work,
LabVIEW supports many data types such as,
I will explain all these data types in brief,
Boolean: Booleans available in two values that are ‘True’ or ‘false’-> these two are indicated by green data wires.
Numeric: Numeric in LabVIEW has many sizes and representations. For example,
Integers: Integers can be used to represent signed or unsigned whole numbers -> blue data wire indications
Doubles and singles: These are the signed numbers can be represented by decimal components-> orange data wire indications
Numeric size in LabVIEW is indicated by bits and size of the possible values.
Strings: Strings in LabVIEW are represented with character sequences-> pink wire data indication
Arrays: Arrays are a group of data types-> indicated by thicker data wires
Clusters: Clusters in LabVIEW are a group of data types -> thick brown data wires
Clusters are available in Error clusters – a special type of cluster used for identifying errors and warnings.
These error clusters are classified into 3 types
LabVIEW dataflow represents the execution of codes; a block diagram in LabVIEW executes the code once receive the data for all required inputs. Once you execute the code in a block diagram, it returns the data which flow into other block diagrams for further executions. The primary function of this dataflow is to control the program executions.

LabVIEW environment offers many options for debugging LabVIEW codes. Let me explain what all the subsets come under this section are,
Broke Run Arrow: This component indicates that code cannot be executed due to errors.
Steps to know:
Highlighting execution: this component used to visualize the code execution
Breakpoints: This component is used to stop the code execution at specific nodes.
Steps to know:
Probes: Probes in LabVIEW used to monitor the data wire values without changing any application execution speed.
While loop in the LabVIEW allows the application to execute repeatedly until some conditions met.
For loops in LabVIEW:
For Loops in LabVIEW used to execute an application repeatedly. They usually iterate over any data set and allow operating any fixed number of times.
Data can be transferred to both the loop structures (While loop and for loop), there are many primitive controllers available to control the data transactions in the LabVIEW loops.

Case Structure in LabVIEW executes the codes based on the conditions of loop value. Let me explain in details,
Modular Code in LabVIEW makes applications easier to develop, debug, and maintain. Let's get into the full detail,
There are lots of advantages available with LabVIEW applications, namely:
Till now I have tried to explain the basic concepts of LabVIEW. In this article, you will know the features and advantages of the LabVIEW tool. LabVIEW is one of the most widely used graphical applications programming tools. It has many advanced features that support even non-programmer can also learn and adapt to many real-time industry applications. I hope this article may help a few of you to get valuable knowledge and learn this LabVIEW application tool.
