Why WebView is better than SCADA plus a web client add-on
Internet technology moves fast, but major SCADA vendors do not. All of the major SCADA vendors on the market today who offer any kind of web client are using technologies from the early days of the Internet, such as ActiveX, Java and ASP. DataHub WebView uses the very latest Microsoft Silverlight technology, which gets you blazing fast screen updates, beautiful graphics, and the highest security standards available in a browser today.No vendor lock-in. You can add DataHub WebView to any PLC, DCS or SCADA system regardless of who makes it. OPC connectivity means you can collect data from all of your different plant systems.It is easy to brand your login page with your company identity, no special tools needed. And you can also add your own symbols and controls so you can see your data on the web exactly how you want to.
Why WebView is better than other Web HMI products
All other products on the market make you pay for the number of data points or web client connections you have in your system (usually both). DataHub WebView breaks from this model by offering you UNLIMITED_CLIENTS.DataHub WebView uses Microsoft Silverlight technology, not just for displaying the web pages, but also for the browser-based editing interface. Other Web HMI products rely on Java and ActiveX plug-ins, which are older and declining web technologies.A web HMI is only as good as the underlying data management platform. DataHub WebView is driven by the class-leading COGENT_DATAHUB, which has more than 15 years of development behind it and is used by CUSTOMERS.DataHub WebView makes it easy for your to customize the interface with your own company branding. It is very easy to use, with a simple installation process that will have you logged in and building web pages in minutes.
