The main elements library of the user interface appended for the "Users manager" frame

The 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:

  • forming a list of controlled users;
  • the ability to view and change user information for: name, full name, description, password and groups;
  • adding new and deleting existing users.

The root page frame of the main elements library of the user interface is significantly expanded and documented

The frame "Root page" is a base element of most interfaces built in OpenSCADA and it was completely documented and significantly expanded for:

  • dynamization of forming the signal object buttons from one base button, with the result possibility of forming very number of signal objects, up to 100 for short names.
  • dynamization and unification of the types of view to their abstract encoding as "viewN", with the result possibility to appoint any other mean to the type of view.
  • correct cleaning the control panels container.

Analysis of the memory consumption and efficiency of the UI module WebVision in the busy environments

The 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 calculation

The 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:

  • Sum, at hour.
  • Average and range.

Debian Linux 10

At releasing the Debian Linux version 10 the OpenSCADA project was adapted to this version for:

- creating the proper building chroot-archives;

- building up the OpenSCADA packages and adaptation in general to build OpenSCADA in the environment of GCC 8 and Qt 5.11;

- expanding the Automation Linux repository and building the new Live disks;

- fixing OpenSCADA for executing the binaries built by GCC 8;

- expanding the automatic builder for building the packages and Live disks.

DDoS on the OpenSCADA server (finished) !!!

Attention, the server of the project OpenSCADA is currently under influence of a DDoS attack, which started at 22.02 05:00 GMT, so there may be short lacks of response!

The attack have finished on the 62920 registered zombie hosts of the attacking botnet and the hosts cleared from the duplicates and their are listed in this file![подробнее]

API of the unified implementation of the DAQ-templates

API 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.[подробнее]

15го сентября 2018г. в городе Киев (Украина): Конференция разработчиков и пользователей свободного ПО — FOSS 2018: "OpenSCADA 0.9 LTS"

Автор, лидер и главный разработчик Роман Савоченко, на конференции, зачитал доклад-анонс версии 0.9LTS проекта OpenSCADA.

Сайт конференции: osdn.org.ua

Новая стабильная версия является результатом шести лет разработки, внедрения в различных решениях, стабилизации и эксплуатации OpenSCADA в её рабочей ветви. И всё это время продолжали выпускаться обновления к 0.8.0 LTS и что будет осуществляться для анонсированной 0.9 LTS.

Основной целью релиза является предоставление обновленной и стабильной платформы построения решений комплексных систем автоматизации и других смежных решений для сообщества пользователей и разработчиков свободного программного обеспечения. Также, релиз предназначен стать актуальным и прочным фундаментом в построении коммерческих решений.[подробнее]
