Live Web-Based HMI Pages in 5 Minutes using DataHub WebView


Georgetown, Ontario (PRWEB) August 23, 2011

Just released from Cogent Real-Time Systems is a 5-minute video that shows how DataHub WebView, a web-based HMI, can be installed, connected to a live data source, used to create a web page showing a trend display, gauge, and progress bar animated by live data, and then publish the page on the web. The video demonstrates the ease of use, stunning graphics, and high data throughput rates of DataHub WebView, as well as its ability to switch from editing to run-time modes at the click of a button.

“Time is money,” said Andrew Thomas, President of Cogent, “and this video shows how quick and easy it is to get going with DataHub WebView.”

The video starts by showing the Cogent DataHub platform being connected to an OPC server acting as a data source, to bring live data into the system. Then, after a few seconds for configuration, DataHub WebView is launched, and appears in Microsoft Internet Explorer. From this web-based editing window, clicking on the icons for a trend, a gauge, and a progress bar pops the controls onto the screen, where they are quickly linked to live data points. Immediately red, green and blue sine waves appear in the trend, the guage needle begins to sweep across the dial, and the progress bar leaps into action. The page is saved and the video shifts to a second computer on the network. The URL for the page is typed into the browser, and the DataHub WebView login screen appears. Within seconds the page loads, and you’re viewing the sine, ramp, and random data from the OPC server in a 3-pen trend, a numerical gauge, and progress bar in a standard web browser. Total time from the installation of Cogent DataHub to seeing the published page: less than 5 minutes.

“This video demonstrates how engineers and system integrators using DataHub WebView can quickly connect symbols and controls to their data sources to build animated pages, while completely bypassing any need for programming, compiling, and deployment,” said Thomas. “Of course, for a real application you’d want to take more than 5 minutes planning your data flow and designing your screens. But technology is no longer the limiting factor that it once was.”

DataHub WebView is a state-of-the-art, rich internet application for delivering real-time data displays in a standard web browser. For existing SCADA systems it is the perfect addition, providing desktop quality graphics and real-time updates of process data in a web browser from anywhere in the world. For new projects, DataHub WebView delivers a self-contained system that includes real-time data delivery, web server and browser-based screen development, all in one easy to install application.

DataHub WebView and the Cogent DataHub are developed and maintained by Cogent Real-Time Systems.
