The ULC UX is a User Interface client for WinCC OA based on the HTML5 technology. It is used as a new alternative to the WinCC OA UI (native UI on Windows and Linux)

The ULC UX can use already engineered panels without any special adaptions.

The ULC UX provides a very high compatibility to the native UI functionality (see Restrictions for further information)

The ULC UX can be used with:

  • Dynamic panels that are using the WinCC OA Control scripting language, as well as
  • Custom EWOs


The ULC UX combines following benefits in a single UI solution:

  • No installation is required on client side
  • Communication is secured by using SSL encryption
  • User management can be performed by using SSO
  • Usage of WinCC OA panels without changes to the existing control scripts
