The synoptic pages (or more briefly, Pages) are the graphical interface of the supervisory system to the user.

The development of a page is done through the graphical editor (X Editor): the page is composed using the shapes and graphic objects available, and eventually linking them to the process database (RTDB) to animate and control the system.

To speed up the development there is a pre-built library of symbols, which can be added new symbols created by the user.
