Web-based HMI: View your process data from anywhere

May 3, 2011
Now you can view your process data from anywhere. Just open your web browser and log on to design, publish, and view HMI screens with professional, interactive graphics. Cogent’s DataHub WebView lets you connect to virtually any system—OPC-enabled hardware and processes, Excel spreadsheets, SQL databases, text files, custom programs, Linux systems, embedded platforms, and even other web pages. You can access new or existing systems without disturbing current investments or infrastructure, and there is no coding, no off-line development system, no compiling, and no deployment. Page designers can edit screens from anywhere over the Internet. They just need to point and click, make edits, save the changes, and let the rest of the team reload the page.

Based on Cogent DataHub real-time middleware, DataHub WebView is fast and secure. Gauges, trends, and other controls update as quickly as network latency allows. With event-based updates, data is available for historical archiving, and nothing is lost in a polling cycle. The DataHub’s robust capacity supports tens of thousands of data points, throughput of thousands of data changes per second, and hundreds of simultaneous web browser connections.
