Give your users what they need to see

From pumps and processes to production and analysis data, your world is full of things you need to view, monitor, or control. With browser-based groov View, you can easily build an operator interface to see and interact with exactly what you need.

Show data from sensors and automation systems, cloud applications, databases, web services, and more. Put the data and controls from different sources together in the way that makes sense for your application and your users.

groov View operator interface

Because you develop the interface yourself, your HMI includes only what you need—and everything you need.
  • Start small. It’s easy to add another indicator or control if you find you want it. Changes are pushed to users automatically.
  • Keep it simple. If your interface is used on computers or web-enabled TVs and on phones, choose which gadgets to show on large or small screens.
  • Include what’s important. Mix data and controls from any manufacturer or software maker on the same page, as needed.
  • Give your authorized users access only to screens they should see. An operator may need to control part of a process, while a manager may only need production data.

groov View was designed on high-performance HMI principles, so the HMI you build is understandable and effective. At the same time, you have complete control over screen appearance.
