With OAS Web HMI, you can create user interfaces to display and interact with real time server data, enabling a whole range of applications on any device with a web browser.
By utilizing standard, platform-agnostic technologies such as HTML5, CSS, Javascript, JQuery, and JSON, web developers can quickly create new HTML5 SCADA interfaces or integrate Web HMI functionality into existing web applications with minimal effort.

Using Web HMI
Getting started with Web HMI is as simple as including the Javascript reference libraries on a web page and adding markup to HTML elements.
Our custom attributes add behaviors to display data values, alter appearance, or even toggle element visibility, all based on real time data streamed from any local or remote OAS Data Engine.
For more complex control and advanced application functionality, developers familiar with Javascript and JQuery can programmatically interact with the real time data using the Web HMI library. With OAS you can develop feature rich HTML5 user interface applications using open standards and technologies.
By utilizing standard web technologies, Web HMI supports user interface development on any web platform such as ASP.NET, .NET MVC, PHP, Ruby on Rails, Java, and more.
