1. Increase of stability, durability and productivity of system.

During works under the given version, and also under its practical adaptation, it was revealed and corrected something about a hundred and fifty errors. Something about a quarter of hundred from them it was revealed owing to biassed testing by Popkov Alexey and about ten by Andrey Kalita. The overwhelming majority of errors was revealed in components of the visual control area.

Except of correction of the set of errors the work on optimization of various components of OpenSCADA has been done. The visual control area(VCA) and its visualizers has undergone to especially appreciable optimization. The basic vector in optimization was optimization of productivity which significance shew itself when loading on the system became to grow.

2. Improvement and stabilization of VCA.

During work with system OpenSCADA the set of improvements and optimizations in VCA and its visualizers has been done.

Let's examine the important improvements:

• Realization of the mechanism of the signalling and notification. Support of three ways of the notification is realized: visual, alarm and speech. As a whole the mechanism is integrated into conception of VCA, it is not fixed and allows to realize the signalling by various user criteria, and not just on traditional for automated control system of technological processes (Industrial Control) criteria.
• For simplification of work with the inspector of attributes were preview of fonts, images and colors, and also dialogues of their direct modification is added.
• In primitive "ElFigure" were added:
  • Support of the filling the closed contours by color and the image. It is also supported the filling by transparent colors.
  • Function of copying inside the primitive is added. This function has allowed to simplify a task of creation of big static images inside of one widget.
  • Support of scaling of thickness of a line and a border on the minimal scale on x and y is added. It has made process of scaling more adequate and has allowed to repaint many elements with the use of simple lines.
• It is unified and it is completely realized in Vision the mechanism of division of the rights of users. Therefore the opportunity of change of the user in a mode of performance with tracking of changing of access rights on separate components is added. The given work has made a reality an opportunity of formation of the user interfaces with division of access rights to separate elements between them.
• Support of automatic scrolling in containers is added. It is made for an opportunity of placement and adequate representation of the big frames on the user interfaces.
• The cache of resources is realized. It is called to increase productivity on highly-dynamised frames with often changed resources such as images and others entities.

Important optimization improvements of visualizer of VCA - Vision:

• Masquerading of pages at the moment of loading with the notification on loading in a mode of performance. It makes the interface more clear and removes questions at long enough opening the big frames.
• Optimization of operations of moving and changing of the sizes of widgets. It has increased responsiveness of the interface in a mode of development.
• The mechanism of storage of individual data of primitives is optimized. It has allowed to reach at once the two purposes, the first purpose - optimization of using of memory and the second purpose - increasing of productivity of formation of primitives of the interface.
• Optimization of deleting and copying-insert of big groups of widgets in a mode of development is done. It has allowed to accelerate considerably group operations with widgts during creation of high-loaded frames.
• Operation of allocation by the mouse and a rectangular is optimized on time. Now on not fast computing systems it is not necessary to wait for updating of the dispatcher of attributes after pressing the button of the mouse with the purpose of allocation of group of widgets by means of rectangular, event of a choice of element is generated on mouse button release.

Significant expansions of WebVision are done. Namely:

• All representations of the primitive of elements of forms (FormEl) became active, that allows to form forms of interaction with the user through the Web-interface.
• support of focus by the mouse and partial support of keyboard focus Is realized. It has added an opportunity of construction of high-grade interfaces of visualization with navigation and control.
