The complex objects conception in the DAQ is formed and documentedIn some cases where an object is only a part of a common automated system and does not require deep detailing to the level of signals and parameters (complex tag) around them, including without the need for archiving, it is convenient to unify them in one representative object of the data source OpenSCADA with appropriate consolidated view and object control as a set of simple attributes with violation elements. The conception is represented currently by the two direct DAQ-templates "SNMP", "UPS" and the representative widget "Object properties" of the "Main elements library of the user interface".

The main elements library of the user interface appended for the extended alarms control framesThe alarm frames serves:
The violations are obtained from the buffer of current-active violations of OpenSCADA and archive(s). In fact, the element implements the primitive "Protocol" functions for violations and extension opportunities. The main user extension is the ability to define visible table fields from a list of options: atm, qttm, nrmtm, lev, cat, mess, prm, dscr, dscrCust{N}, alrm, cmnt. Sponsored...

The main elements library of the user interface appended for the "Users manager" frameThe element-frame serves to control users from the user interface itself. That is, typically this feature is provided to the SCADA programmer at the Security subsystem configuration, but sometimes there is a need to provide this capability from the user interface and with a few restrictions on controlled users and their groups that this frame performs and generally provides:

The root page frame of the main elements library of the user interface is significantly expanded and documentedThe frame "Root page" is a base element of most interfaces built in OpenSCADA and it was completely documented and significantly expanded for:

Analysis of the memory consumption and efficiency of the UI module WebVision in the busy environmentsThe module UI.WebVision was observed in extra memory consumption on a real big task working on Debian 9. There were performed several actions of measuring about this module work on different Debian versions: 7, 8, 9, 10; where we have seen the clear degradation of effectivity of the memory allocation on Debian versions from 8. Contacting the Debian community we revealed this problem as a disadvantage of GLibC in implementing memory arenas, which can be highly fragmentated in program environments what actively recreating the threads, due to linking the arenas to threads. So, to fix this behaviour, we need to set the environment variable MALLOC_ARENA_MAX=1, what was be done for all live disks of the automation Linux distributive.

The graphics group frames of the main elements library of the user interface appended for the graphic parameter calculationThe element implements a dialog of user calculation of the selected graph parameter for the graphically visible data. The user is given an option to select calculations from the built-in library, the privileged user ("root" or in the "ITW" group) has the opportunity to edit or write their own calculation procedure. In general, the built-in library currently contains the following functions of the user calculation:

Completion of revision of the virtual-demo projectsAll virtual-demo projects and their libraries were completed in whole revision of their documentation and database files, for: two styles-themes support, removing Cyrillic symbols from identifiers, unification the identifiers and fixing most texts.[more]

On 18...21 April 2019 in the city Lviv (Ukraine): The International Research and Practice Conference "FOSS Lviv"The International Research and Practice Conference “FOSS Lviv” took place in Ivan Franko National University of Lviv on April, 18 – 21.[more]

API of the unified implementation of the DAQ-templatesAPI of the unified implementation of the DAQ-templates has been implemented, applied and substantially tested. Currently, this API is applied on the primary modules of the subsystem "Data acquisition", that is LogicLev, ModBus, Siemens, and as an optional feature for the controller object of the JavaLikeCalc module. From modules of other subsystems to the templates support, the protocol modules UserProtocol, ModBus and the graphical interface module WebUser have been adapted. Moreover, the use of templates in the modules UserProtocol and WebUser conceptually improved their functions and expanded the ability to create complex templates.[more]

On 15 September 2018 in city Kyiv (Ukraine): The conference of developers and users of the free software — FOSS 2018: "OpenSCADA 0.9 LTS"On the conference, the project author, leader and main developer Roman Savochenko read the report-announce of 0.9 LTS version of the project OpenSCADA. The conference site is: osdn.org.ua The new stable version is the result of six years of development, implementation of various solutions, stabilization and exploitation of OpenSCADA in its Work branch. But all this time, updates for 0.8.0 LTS continued to be released and what would happen for the announced 0.9 LTS. The main purpose of the release is to provide an updated and stable platform for building integrated automation systems and other adjacent solutions for the community of users and developers of the free software. Also, the release is intended to become an actual and solid foundation for commercial solutions building.[more] |
