OpenSCADA has extremely flexible architecture that allows you to create external interfaces, including user, in any manner and taste. For example, the OpenSCADA configuration environment available now as by means of the Qt-library, and also the Web-based.
At the same time, independent creation of the VCA implementations in different basis may cause the inability to use the configuration of one VCA into another one. That is inconvenient and limited from the user side, as well as costly in terms of implementation and follow-up support.
In order to avoid these problems, as well as to create as soon as possible the full spectrum of different types of VCA, the generic concept of VCA is established. The result of this project — this direct visualization module (based on the Web-technologies), direct visualization module Vision and the VCA engine VCAEngine.
