Web-based SCADA HMI Software
Web-based Trend allows us to display real time and historical data in an trend 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.

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.
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.
Because HTML HMI is built upon industry standard web development technologies such as as jQuery, JSON, CSS and HTML5, integration with other open-source libraries is fairly straightforward. In this example, an HTML5 canvas-based gauge from the popular Steelseries library is used to display a data point.
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 HMI
- Unique markup option quickly adds live data to existing HTML pages
- Programmatic JS interface allows for advanced application UI development
- Can run on ANY web application platform that generates or delivers HTML including: ASP.NET and .NET MVC, PHP, Ruby on Rails, NodeJS, Static HTML sites like WordPress …and more!
- Supports authentication and secure communications over SSL
- Requires no plugins, Java applets, or ActiveX controls to execute; just point your browser to your web application to start
- Requires no compilation or packaging for deployment; supports file copy deployment or integration with your own deployment methods
