What Is NI Application Web Server?

The NI Application Web Server is a powerful tool that allows you to create web-based user interfaces for your LabVIEW applications. It provides a convenient way to access and control your LabVIEW application from any device with a web browser, such as a computer, tablet, or smartphone.

Key Features

The NI Application Web Server offers several key features that make it a valuable tool for developers:

  • Remote Access: With the web server, you can access your LabVIEW application remotely without the need for any additional software. This means you can monitor and control your application from anywhere in the world as long as you have an internet connection.
  • Platform Independence: The web-based user interface created using the NI Application Web Server is platform-independent. It works seamlessly across different operating systems, such as Windows, macOS, and Linux.
  • Customizable Interface: You can design a user-friendly and visually appealing interface using HTML and CSS.

    The web server allows you to create buttons, sliders, graphs, and other interactive elements to control your LabVIEW application.

  • Data Visualization: The web server enables real-time data visualization by displaying graphs and charts. You can monitor live data from your LabVIEW application in a graphical format using the built-in charting capabilities of HTML5.
  • Data Logging: The NI Application Web Server supports data logging functionality, allowing you to store data generated by your LabVIEW application in a database or file. This feature is useful for analysis and future reference.

Getting Started

To start using the NI Application Web Server, follow these steps:

  1. Install the Software: Ensure that you have LabVIEW installed on your system. The NI Application Web Server is included with LabVIEW, so there’s no need for a separate installation.
  2. Create a Web-based User Interface: Design your web-based user interface using HTML and CSS.

    You can use the built-in tools in LabVIEW to create HTML templates or modify existing templates.

  3. Add Functionality: Use LabVIEW to add functionality to your web-based user interface. You can create VIs (Virtual Instruments) that communicate with the web server and perform actions based on user inputs.
  4. Deploy Your Application: Once you are satisfied with your web-based interface, deploy your LabVIEW application along with the NI Application Web Server. This will make your application accessible through a web browser.

Note:

The NI Application Web Server requires a compatible version of LabVIEW and a supported web browser. Make sure to check the documentation provided by National Instruments for detailed system requirements and compatibility information.

In conclusion, the NI Application Web Server is a powerful tool that allows you to create web-based user interfaces for your LabVIEW applications. Its features, such as remote access, platform independence, customizable interface, data visualization, and data logging make it an essential component for developing modern and accessible applications.
