Browser Compatibility
The OAS HMI with web browser technology is compatible with PC, Mac, Android, iOS, mobile, tablets, MS Edge, Chrome, Safari, and more. It uses standard web technologies like HTML, JavaScript, and CSS, with no need for browser plugins or custom installations.
Implementation Options
You are free to mix and match both declarative markup syntax and direct JavaScript control of data. This means you can integrate live data into your application quickly or add your own custom logic where needed.
Use with Existing Frameworks
Because Web HMI uses standard HTML and Javascript, you can integrate it within your own custom application, or add behaviors to another framework like ASP.NET, Ruby on Rails, PHP, Angular, React and VueJS.
Ease of Deployment
Add one JavaScript file to your project, and the HMI web display builder is ready. The lightweight SDK deploys with your existing resources and fits seamlessly into your existing codebase.
Security
All client to server communications can be locked down using SSL. Simply enable SSL in the OAS server and data is encrypted over the wire between the browser and OAS.
Direct Data Delivery
All OAS data is directly sent and received between the client and the OAS server, which eliminates the need to implement server-side handling, and removing load from your web application server.
Using Web HMI
Markup Syntax
Add real-time functionality to any HTML element using a simple markup attribute. Update values, change colors, or trigger visual changes using live OAS Tag data.
Behaviors can also respond to bad data quality or dropped data connections, helping you create resilient and interactive web interfaces.
Full Javascript Control
Built-in JavaScript functions allow developers to authenticate, read live values, and update Tag values. All interactions go through the OAS Security layer to prevent unauthorized access. Client-side logic can also support dynamic behaviors, responsive visuals, and real-time updates, all of which help create powerful web HMI SCADA systems.
Markup and JavaScript can be combined for projects that require both rapid implementation and deep customization.


Looking for a No-Code Solution?
The OAS Open UIEngine is perfect for rapid development when you want to build simple or complex applications but do not have the resources for custom web development. UIEngine is a complete web-based application development tool and no-code solution for HMI / SCADA using an intuitive drag-and-drop interface.

Web HMI Use Cases
Inject Live Data
With existing web applications, it is extremely simple to inject live data into elements, bringing static websites to life with up-to-date KPIs. No need to rewrite your applications or to start from square one.
Leverage Expertise
If your organization currently has the skills and expertise to build and deploy web solutions, the low barrier to entry with Web HMI allows you to rapidly create new classes of applications within your enterprise.
