Browser Compatibility
Access your industrial data analytics in all modern browsers like MS Edge, Chrome, Safari, and more. Compatible with Windows, macOS, iOS, and Android, Web Trend is built with standard technologies, requiring no plugins or extra installations.
Use with Existing Frameworks
Since Web Trend is built with standard HTML and JavaScript, it works easily with platforms like ASP.NET, Ruby on Rails, PHP, Angular, React, and VueJS. This gives you the flexibility to plug data analytics for manufacturing and industrial IoT data analytics into your custom dashboards without a lot of extra work.
Security
All data transmissions are encrypted using SSL when enabled in the OAS server. This ensures your industrial data analytics software remains secure during browser-server communication.
Direct Data Delivery
OAS delivers data directly between server and client without relying on middle-layer services. This reduces web server load and enables fast, responsive SCADA analytics and manufacturing data analytics.
Using Web Trend
Configuration Syntax
Within your web application code, you’ll set up the Web Trend data feed by choosing which OAS Tags to monitor, adding metadata, and selecting display options. You’ll also create a function that runs as data streams to the client.
From there, you can plug the data into your own code, use it with charting tools like ChartJS or Flot Charts, or run client-side calculations . OAS handles all of the data collection, communications, and delivery, while leaving you free to decide how that data is displayed.

Looking for a No-Code Solution?
The OAS Open UIEngine allows users to create full-featured HMI and SCADA interfaces without writing code. Its drag-and-drop design tools and built-in Trend Component make it easy to display live and historical data. Perfect for building scalable industrial data analytics software when development resources are limited.
