Level2 screens

In the Level2 there is a minor difference of the screen concept from that one in the WebHMI:

In the WebHMI, you can change screen layout right on the screen page, while in the Level2 you make screen layout on a special Manage page, afterwards you can only change the properites of the widgets from the screen view, not detailed settings.

Adding a screen

You create new screens in the side panel Screens/Manage sub-menu with a +New screen button:

By clicking the screen's title or button you'll get to the screen edit page.

Template means that the screen was cloned with keeping binding with the parent screen. Then in the cloned screen the parent's name will be listed in this column. Read more in the further article.

Group property wraps a set of screens belonginng to it into one side panel pull-down sub-menu.

Enable property switchs the screen visibility in the side panel on or off.

Editing screen's properties

  • Title - a name the screen will be listed with
  • Group - see previous paragraph
  • Theme - 2 options are available (Gray, White)
  • Available to roles - who mays to access the screen

Editing screen visual layout

By clicking the screen's title or button you'll get to the screen edit page. Then by dragging & dropping & setting up available widgets onto the screen page you can create your screen layout.
