Web-based SCADA HMI software allows us to create user interfaces to display and interact with real-time data, enabling a whole range of applications on any device with a web browser.

SCADA HMI Software

Web-based Trend allows us to display real-time and historical data in a trending format on any device with a web browser.

Web-based Alarm allows us to display real-time and historical alarms in an interactive table, viewable on any device with a web browser.

To help you best understand how Web HMI works take some time to check outĀ live demo

Web SCADA HMI

Tank Level Control

This example demonstrates how Web HMI can be used to build a user interface that displays numerical, textual, and spatial information while allowing the user to control multiple aspects of the system.

In this case, the user can toggle on/off the various pumps and valves.

HMI Display

Web or HTML-based HMI can capture and display server values in many HTML elements, including input fields.

The value will not affect the styling of the elements in any way, so your standard layout, look, and feel can be maintained.

Web HMI Values

Web Objects

Because HTML HMI is built upon industry-standard web development technologies such as jQuery,Ā JSON,Ā CSSĀ andĀ HTML5, integration with other open-source libraries is fairly straightforward.

In this example, an HTML5 canvas-based gauge from the popularĀ Steelseries libraryĀ is used to display a data point.

Digital Pressure Gauge Animation

Real-time features of Web-based HMI are

  • Real-Time & Historical Trends
  • Real-Time and Historical Alarms
  • Mobile Updates (optional)
  • Multi-devices supported (desktop, mobile, tablet)

Advantages of Web-based SCADA HMIĀ 

  • Compatible with ALL browsersĀ on Mac, PC, Linux, andĀ mobile devicesĀ capable of displaying HTML5 and executing JavaScript, including: Chrome, Firefox, Safari, Internet Explorer (8+, 9+ recommended), Mobile Safari and Chrome on iOS, Mobile browsers on Android
  • UtilizesĀ open standardsĀ for HTML5, JavaScript, and CSS
  • Unique markup option quickly adds live data to existing HTML pages
  • Programmatic JS interface allows for advanced application UI development
  • CanĀ run on ANY web application platform that generates or delivers HTMLĀ including:Ā ASP.NET and .NET MVC,Ā PHP,Ā Ruby on Rails,Ā NodeJS,Ā Static HTML sites like WordPress …and more!
  • SupportsĀ authentication and secure communications over SSL
  • RequiresĀ no plugins, Java applets, or ActiveX controlsĀ to execute; just point your browser to your web application to start
  • RequiresĀ no compilation or packaging for deployment; supports file copy deployment or integration with your own deployment methods
  • Real time data delivered directly to your browser, reducing load on your web application server
