2 Purpose

Functional purpose of the development is to create the generic concept of the VCA and its use in the development of specific modules of VCA implementation for the OpenSCADA system. The development of modules of VCA implementation based on the Qt-library and WEB-technologies is planned.

The developing VCA modules, in general, are provide for:

• Visualization:
  • operational (current) information: parameters' values of technological process (TP), violations of the regulation borders (alarms);
  • archival data: parameters' values; text messages on violations of TP, actions of the user's control of TP, as well as system messages from all subsystems of OpenSCADA.
• Control of the technological equipment and the parameters of TP: change the settings and operation modes of the control circuits, change anti-emergency protection system settings, enter numeric data.
• Build reports and other report documentation.

Operating destination of the development is:

• broadening the scope of the OpenSCADA system due to the functions of VCA module;
• full use of the OpenSCADA system for generic and TP control.
