The graphical interface of the system may consist of one or more pages depending on the synoptic information to show. Typically a supervision project consists of multiple pages through which the user can browse to access the data and commands they need.

When you start the viewer, it opens the synoptic configured as Home Page in X View Settings. To allow navigation between the Synoptics being viewed is necessary to provide controls properly configured to achieve access to the page they refer to. 

The functions of the pages accessed are available as Built-in actions.
