The current stable version of long term support of the project OpenSCADA is 0.8 which released in year 2012 and updates of it have released all this time. The main developing process continued into the work on version 0.9 which to the year (2017) end must achieve the planed stage and as the result a new stable version of long term support 0.9 LTS must be released. The report previously presents the project of open SCADA system version 0.9 in view of its features into the common and related industries, and into representative examples of its applying.

Report/Article

The project OpenSCADA founded in year 2003 by Roman Savochenko as a free implementation of system of Supervisory Control and Data Acquisition (SCADA) or Human Machine Interface (HMI), grounding on an experience into using and developing of commercial SCADA-systems.

SCADA or HMI systems are generically appointed and used to operational and responsible control by human for working of the complex technological equipment of different production companions.

For now the OpenSCADA project is an advanced SCADA/HMI system this is wide enough used as for the direct appointment and, due to self flexibility, into more adjacent areas that is: realtime dynamic models, imitators and training apparatus of technological processes, environments of execution Programming Logical Controllers (PLC), server hardware monitoring, smart houses and home automation. With some limits and modifications, mostly into the internal environment, OpenSCADA can be used into that areas: billing systems, Enterprise Resources Management (ERP), Accounting and Bookkeeping. Then OpenSCADA we can confidently call in general — the system of working with data in realtime.

Due the project is free, it's mostly provided under GPLv2 license, user can get free access to source codes of the project, to build and to use it. Ready to use builds and packages of the program are provided now for more known Linux distributives and environments on the main project's resource oscada.org. A free and limited support is provided on the project forum for the free-obtained source codes, binary archives or packages, and mostly for prompt representing and nonspecific to user environment problems. For the full support get a user allowed to purchase a package of commercial technical support from the project developers. Besides the commercial support from developers user allowed to purchase services for solutions on OpenSCADA developing, both from the developers and from the third party integrators. Missed functions and extensions, which aren't in the contradictory to the project conception, user also can order to implement for the OpenSCADA developers.

The main process of developing goes by the author and main developer OpenSCADA Roman Savochenko and he's pointed the process respectively. The developing exclusively goes into the work version by the targeting stabilization and extension during the user solutions implementing. From begin of year 2016 the roadmap was updated and the process of preparing and releasing of the stable version 0.9 LTS was started after an achievement of the current work version to some acceptable stability level at introduction of all key changes into the project architecture and conception. The previous/current stable version 0.8 LTS has been continued to updating all the time!

Main time and efforts of the developers currently pointed to finish the conditional tasks of a new stable version 0.9 LTS releasing.

Practical solution, built on OpenSCADA

A face of the further release 0.9 LTS is a proper work version. This version developing and stabilization have continued during the last five years by implementation to various solutions. Grounding on OpenSCADA there built more solutions directly by the author, by his participation but also without him know then the following solutions pointed once to solutions of the author or related his.

Automation systems of control for technological processes (ASC TP) and environments of execution of PLC:

• “Automation System of the Metropolitan”, 2016 (Optima). Support is going now ...

Other solutions about the project OpenSCADA and its infrastructure:

• The self server of the project OpenSCADA and the internet channel of connection, 2014. Besides the presented services on the new server was deployed next new ones: tunneling connection to provide remote service; the automation project's builder; “AGLKS” and “Boiler” models with a demonstration of Web-access from outside; Smart House on the OpenSCADA base with functions of monitoring the server and ERP.

• The Automatic builder of the project OpenSCADA (2015) to simplify builds and rebuilds of packages, binary archives and live disks of the distributive of automation based on OpenSCADA. The builder means checking the repositories of source codes OpenSCADA Subversion and building the two branches, that is: Stable (LTS), for now it's 0.8, and Work, for now it's 0.9.

• The Linux Distributive of the Automation Systems based on the project OpenSCADA (2012) split and set formal into the project “Automation Linux distributive of the project OpenSCADA”. The repositories of packages firstly include same OpenSCADA packages and also a series of packages adapted and built specially for the project. Currently the base of the automation distributive was replaced from Linux distributive ALTLinux to Debian, in more reasons of the technical a political character. The Live disks, and the “Automation Linux distributive of the project OpenSCADA” currently, create:

  • to provide a fast and simplest method of acquaintance and deploying solutions with OpenSCADA and into the tested and reliable environment of Linux;

  • as a platform for PLC and paneled PC/PLC of the hardware architecture x86, x86_64 and ARM;

  • as a platform for complex solutions of the automation systems in creation of an assembled disk of the automation system project in connection with an installer of the typical, optimized and stabilized environment; with the documentation and other files of the project part's configuration;

  • to provide a service functions about the author's program environment and hardware and the solutions of automation systems.

OpenSCADA 0.9 LTS

Future stable version you can mostly estimate now and don't wait for an official announce and branching from the Work version. That is by using regular builds of the actual Work version in view of: live disks, packages and repositories of the packages. And counting a fact that the actual Stable version supports from its official release (already released 17 updates) then most functions have presented there; and for target formalization to concrete functions you can use the current stable version even.

Currently there are actively performing works for two tasks of the cross platforming, that is:

• Modules of the present Web-interfaces expanding to a level of modern Web-interfaces and nearliest to the functional properties of their analogues on the library Qt.

• Adaption to execution on the program platform “Android”.

From the already present features and specialties of the future release 0.9 LTS we must note next, system ones:

• Significant stabilization of OpenSCADA core, unification of control for internal resources and expanding for features of debugging by user. That is the code of dynamic object OpenSCADA have already been included to the current stable branch by the update 17.

• Expanding for the redundancy mechanism which potentially means for redundancy any one subsystem and currently there is implemented redundancy for subsystems “Data Acquisition” and “Archiving”.

• Support for hierarchical parameters of objects of controller of data acquisition.

• A mechanism of dynamic translation messages which means a possibility of changing language of the user interface by the same user changing (not implemented in full).

• A mechanism to call/open documentation of a project which involves updating the offline documentation with the stable version updating at modernization of the Knowledge Base (Wiki) of the project OpenSCADA.

• Moving to the developing scheme Work/LTS that is developing into the work version and releasing updates to the stable version by back-porting of the compatible changes from the work version. In fact the moving was done in year 2013 when 0.8 LTS was admitted as the current stable version and 0.9 Work was admitted as the current work version.

• Changing of versions of the modules performs together with changes into code of the module and before their uploading to the repository of source codes.

• Unification and developing for a new mechanism of the program starting from the program-manager of projects OpenSCADA. The mechanism will possible be expanded by its moving to the module UI.QTStarter, in way of adaption to the platform “Android”.

• Data sources of the network type have moved to preferable implementation as a procedure of the internal environment OpenSCADA from a standalone module of OpenSCADA, for low and middle complexity of the protocols. Currently there have implemented support for next hardware and functions by the conception of user protocol:

  • Sending for SMS messages (SMS) and electronic mails (SMTP).

  • Uninterruptible Power Supply (UPS) as an object of data with attributes of values.

  • Simple sensors: Elemer TM510x; EDWARDS TURBOMOLECULAR PUMPS (SCU750); Sycon Multi Drop Protocol (SMDP); Power supply of the turbo-molecular pump (TMP-xx03); Temperature measurement IT-3 (IT3); IVE-452HS-02; OPTRIS CT/CTL; CTR 100, 101.

  • Heat counter computer VKT7.

  • IEC-60870-104.

Conclusion

The integrated and dynamic SCADA-system OpenSCADA is advanced, ready to using into the complex industrial conditions to perform full spectrum of tasks of automation control of the technological processes and automation in general.

In fact OpenSCADA currently is a system for working in realtime with the dynamic data, and its development directed by the author to finish the release conditions and same the new stable version 0.9 LTS releasing on the background of the common activity of the targeting stabilization, supporting and extension.

The actual achievements and solutions of the project OpenSCADA have performed on the program platform Linux and the hardware platforms x86_32, x86_64, ARM. But in the process of approximation to the version 0.9 LTS there are performing now work to expand the project's features to its adaption for work on other platforms, through the Web-interfaces raising to a level of the high readiness and stability and adaption to work on the program platform Android also.
