OpenSCADA 0.7.1


Оглавление

Introduction

This release is a planned one of a working version of OpenSCADA, which are usually made at intervals of 3-4 months. The main purpose of this release is the implementation of commercial service on the OpenSCADA basis and adaptation to the ARM hardware. In addition to the main purposes within the limits of this release a great work for stabilization, cleaning the source code, as well as for the full empowerment is made.


This document is the processing (compilation) of <ChangeLog> document of the OpenSCADA system of 0.7.1 version, which is designed for briefly and clearly covering the new features and changes of the OpenSCADA system. To get acquainted with all the changes in the OpenSCADA system it is possible in the .file ChangeLog from the distribution kit of the system, or here: http://oscada.org/websvn/filedetails.php?repname=OpenSCADA&path=%2Ftrunk%2FOpenSCADA%2FChangeLog .


The key features of this version are:


New and updated modules are:

1 Implementation of planned tasks

In accordance with the plane of the release there were made the following tasks:

2 Optimization, stability, sustainability and system performance increasing

During the work on this version, as well as its practical adaptation, it was discovered and corrected in a total of about 90 errors. In general, work has been done on cleaning code from the compiler's warnings with the "-Wall" flag:


Lets list the most significant errors correction of which significantly affected the increasing of stability:


Optimization and performance improvement :

3 Improvement and stabilization of the graphics subsystem

The notable work was made within the graphics system, namely in the VCA engine modules UI.VCAEngine, visualizers UI.Vision and UI.WebVision, as well as in the configurators. The changes were provided for stabilization, the optimization of memory consumption and improvement of user's properties.


Improvements of the graphics subsystem:

4 Formation and stabilization of the user programming API

It was continued the development of object API of the user programming, which provides the integration of user's functions in the object's tree of OpenSCADA. In addition, a number of changes were made to the existing library of the user's API functions.


In particular the following changes were made:

5 System-wide expansions

There have been made the significant changes and extensions to the system-wide API of the OpenSCADA system with the purpose of the general stabilization and in view of the general measures for cleaning the source code and reorganizing the sources' tree:

Conclusion

The OpenSCADA system gets the push for the implementation of real hardware multiplatform, whereby the project's code has been largely cleaned up and made multiplatform. These developments will enable the project to continue moving toward the hardware multiplatform, as well as the implementation of the program multiplatform that is scheduled after the next LTS release 0.8.0.


Work also is continued on improving the overall functionality, simplicity and ease of using with the general improvement of the quality of service based on the OpenSCADA system.
