Implementation of basic functions of the development framework of the user interface in the presentation(visualization) module UI.Vision

6.2 Visualization interface projects

6.3 Sessions of the project's running

Forming of hierarchical final visualization widgets' tree based on the project for which the session is opened.

Forming values' frames for the final visualization widgets' calculation procedures.

Links on the data sources of OpenSCADA processing.

Forming window of the project execution (Runtime).

Visualization of the project's frames in the "Runtime" mode with periodic updating of the content.
