1 Implementation of planned tasks

In accordance with the plan of the release there were performed the following tasks:

• Extension of the API of user programming with the functions:
  • For the session management it has been added the library of user functions to the module UI.VCAEngine. The library includes the following functions: vcaWdgList(), vcaNodePresent(), vcaAttrList(), vcaAttrGet(), vcaAttrSet() è vcaSesUser().
  • Management of the controllers of the subsystem "Data acquisition" and of the other OpenSCADA objects was implemented by adding the type of data Object and creation of the user request FLibSYS.xmlCntrReq() to the management interface.
• The module DAQ.ModBus is supplemented with the protocol module ModBus, that allowed to work in server (slave) mode of the ModBus network.
• The redundancy mechanisms are implemented. In the subsystem "Data acquisition" it is added the mechanism of horizontal redundancy and all the modules of this subsystem are adapted to support the horizontal redundancy. The functions of the vertical redundancy are added in the module DAQ.DAQGate, including the restoration of archives and archives locking of the remote stations. The mechanism of the hot compensation of the holes in the archives from the archives of the back-up sources is implemented.
• Into the DAQ.JavaLikeCalc it is added the full support of the objects and arrays. The mechanisms of access to the elements ".prop" and "[prop]" are implemented. The functions of objects and of their execution are implemented. The language is unified at whole to work with different data types with the help of the single command of the virtual machine.
• The styles support for the VCA interfaces is added.
• Implementation of the primitives "Link" and "Function" of the VCA. -- This work was not done and is moved on to the next release.

2 Optimization, stability, sustainability and system performance increasing.

While working on this version, as well as its practical adaptation, it was discovered and corrected in a total of more than 200 errors.

Except the correction of the errors the work under the optimization of the various components of OpenSCADA. Particularly the noticeable optimization was made in the visualization control area (VCA) and in its visualizers. The main vector in the optimization was the optimization of memory usage.

Here are the most significant error, correction of which has the significant effect on improving of the stability:

• Wide-system:
  • The configuration files for the remote connection by default are fixed.
  • Compiling of the main starting program is separated from the library compiling into the directory src_call/ in order to ensure the error-free compiling of RPM-packages in the multithreaded mode.
  • Starting script of the user mode "openscada_start" is corrected in order to copy the configuration file oscada_start.xml to the /.openscada/oscada.xml and to local using of it.
  • The adaption for the QT 4.5 using is done. The variable of the environment LC_NUMERIC = C is globally added in order to finally fix the problems of the separator in the real numbers in the different locales.
  • Mode of cache using by the system database is changed to use only in the case of absence of the main database.
  • The resource for access to the XML-tree of configuration file is added. To access the XML-tree not the mode of the generation of the errors exceptions is used, this corrected the leakage of resources (Stack) in some contexts.
  • The resource conflict arises when trying to delete one and the same child element of the OpenSCADA component from the different threads is fixed.
  • The resource for access to the container structure of the elements TElem is added. Conflicts were detected using the general TElem from different TConfig of the different threads in UI.WebVision.
• The support for updating of the status of connection of the remote stations in the module UI.QTCfg is added.
• Into the module Protocol.HTTP:
  • The support for the "~ KeepAlive" mode is added, which is needed for normal operation of the Opera WEB-browser.
  • The omission and not full processing of the the character '\r' at the end of the HTTP protocol lines is fixed. Fixed the work in Konqueror 4.
• VCA:
  • A lot of fixes and improvements in conjunction of the visualization and archiving are made.
  • The work of the trend primitive "Diagram" of the VCA is fixed when working on long time intervals. The work with individually selected archiver is fixed.
  • Algorithm of the identification of the fact of modifying the attributes and widgets of the module UI.VCAEngine whilr the execution of projects is submitted to the function modifChk() and retreated to take into account the possibility of overflow and reset of the cycles of execution counter of the visualization interface.
• A lot of bug fixes are made in the module DAQ.ModBus and the reconstruction for the support of various interfaces, including ModBus/ASCII is implemented. The record to the controller is made only in the case of a real change in values and record of the not EVAL values.
• For the outgoing transport of the module Transport.Sockets the reconnection and restoration of the session is fixed, it is also added the controlled timeout of the connection.
• The export of large areas of the archive is fixed, as well as the function of management of the requests restrictions for buffers with the fixed size.

Optimization and productivity improvement:

• Working mode with the DB tables is changed to the one which do not close the tables immediately after the completion of work with them. Closing is made in a minute after the last use of the table. This approach significantly increased the speed of access to the database.
• The cache of the resources is implemented in the module UI.WebVision. It increases the productivity in the construction of images of ElFigure primitives based on the images.
• Database Structure of the VCA is changed to improve the productivity and to avoid the lost of records in the database. DB API version is set to 2.
• The individual mechanism to block the outgoing transports is added. It is used for the exclusive access to transport without blocking of the entire protocol in the DAQ.ModBus and Protocol.SelfSystem.
• Optimizing of the memory usage:
  • The data type TVariant for the clear storage of date of different types. The object is used to obtain the direct access to the attributes of widgets "id" and "path" and to avoid the excessive storage of these attributes in the module VCA UI.VCAEngine.
  • The global resource object and its use are standardized. For the resource to the read-write the POSIX functions pthread_rwlock_ *() are used.
  • The container of the children groups in the TCntrNode is made the dynamic one.
  • The mechanism for storing the attributes in the VCA widget is simplified.
  • The description object of the VCA attributes TFld is used only once for the inherited attributes. The memory using is reduced by the 30%.

3 Improvement and stabilization of the VCA.

Significant changes have been implemented within the visual control area (VCA), namely in the VCA engine modules UI.VCAEngine, in the visualizers UI.Vision and ~ UI.WebVision. The changes were aimed to the stabilizing, optimizing of memory usage and improvement of the user functions of the VCA.

Improvements of the VCA:

• The transfer of the translation of the main QT dialogues to the standard I18N.
• The functions of the user API for enhanced access to the elements of the session of the project from the scripts of elements'(widgets') of visualization are added.
• The support of alpha channel, ie translucency, in the indication of colors of all elements of the VCA primitive ElFigure is added.
• Attribute "root" of the VCA is moved to the main widgets' attributes' container . Attribute "parent" is added to provide information about the parent widget. The attributes "tipTool" and "tipStatus" are added to provide an opportunity for providing the VCA widgets with the contextual help in the module of the visualization engine UI.VCAEngine.
• In the UI.WebVision module the conception of forming the image of the primitive ElFigure is changed to the formation of images with filling in the individual images and their subsequent integration into the resulting image.
• The mechanism of the VCA widgets' changes clear is implemented. It is often need to reset the local changes and to return to the inherited properties.
• The support for the context menu for widgets in the execution mode of the VCA projects is implemented.
• The hiding of the the menu bar in the mode of execution of the project by the UI.Vision module for unprivileged users is implemented. Menu Bar in the execution mode is now positioned as the tool of the OpenSCADA's administrator, which contain system-wide functions. Print and export functions are duplicated on the status bar.
• The clock on the status panel is added in the execution mode of the project by the UI.Vision module for full-screen performance.
• The basic support for the multi-display systems is implemented in the UI.Vision module.
• Changes in the structure of the VCA database are added to improve performance and to avoid the lost of records in the database. The version of the DB structure of the VCA is increased to 2.
• Into the VCA primitive "Diagram" it is added the representation of the frequency spectrum of the archive data values.
• The user function vcaSesUser() into the user API of the VCA is added.
• VCA: Into the primitive "Protocol" the property of the sorting order and description of elements' design property are added. Check for disable of the trends, including the condition of the not correct color are added to the primitive Diagram.
• The support of styles is added.

4 Translation of documents in English and the program's interface in German. Multi-language database.
