The Embedded HMI application is designed as a set of screen masks. To create a new screen, run the "Insert Item / New Screen" command from the context menu in the Workspace. Each screen is identified by a name (ID) such as shown in the workspace tree. You can change this ID using the "Rename" command.

The hmiSetScreen function enables you to dynamically change the active screen mask from IEC programs.

Screen IDs can be directly used in IEC programs as integer values. You don't need to declare or define again IDs in the IEC application. Their name are automatically known by the compiler.

Double-click on a screen in the Workspace to edit its contents. A screen mask is designed as:

- some properties visible when no object is selected,

- a set of graphic objects having static or dynamic properties.
