License Information - Online License Handling

On the Online License Handling tab, you can open the license portal in WinCC OA or in your browser. You can also update your license automatically. This will work if you're on the right computer or if the container is also connected. If not, you'll just need to switch to offline management. When you start the update, a window opens. Select the license container for which you want to update the license.
