Web Alarm Monitoring for HMI and SCADA Systems
View real-time and historical HMI alarms and SCADA alarm data from any device using your web browser. With Open Automation Software (OAS), developers can build interactive SCADA alarm notification tools using standard technologies such as HTML5, CSS, and JavaScript. It's a flexible way to manage IIoT web-based alarms directly in your existing or new web apps.
Add Real Time and Historical Alarms to Your Web Apps
OAS Web Alarm integrates with existing web applications as well as new applications built on any number of front-end frameworks. You can build it with simple HTML and JavaScript, or utilize a front end web development platform. Web Alarm displays real time and historical alarm data in an interactive or animated graphical format on any device with a web browser.

Browser Compatibility
Web Alarm runs in all modern browsers, including Chrome, Safari, Edge, and Firefox, on any device, such as a PC, Mac, Android, or iOS. Since it’s built with HTML, JavaScript, and CSS, you can view and manage web HMI alarm data with no additional installation or plugins required.
Use with Existing Frameworks
Because Web Alarm 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.
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 removes load from your web application server.
Using Web Alarm
Configuration Syntax
Within your web application code, you can define the configuration of the Web Alarm data feed, including how to filter Alarms, display options, and more. Use JavaScript events to create a tailored user experience for interacting with HMI alarms and SCADA alarm notifications.
Looking for a No-Code Solution?
Use the OAS Open UIEngine to build responsive alarm interfaces with zero coding. This no-code tool includes an intuitive drag-and-drop interface and a built-in Alarm Component that makes it easy to display both real-time and historical web HMI alarm data. It’s perfect for teams that want to move fast without custom development.
Common Questions
What skills are necessary to use Web Alarm?
