Welcome to the main site of the open SCADA project

OpenSCADA system is an open implementation of SCADA (Supervisory Control And Data Acquisition) and HMI (Human-Machine Interface) systems. The main properties of the system are: openness(Opens internal link in current windowGPL,GFDL), multiplatform, modularity and scalability. Read more here or learn system's functional characteristics here.

The site contains materials about OpenSCADA system and serves for granting the information on project, and also for the system development process control, together with the project's Wiki-resource.

On 27...30 April 2017 in city Lviv (Ukraine): The International Research and Practice Conference "FOSS Lviv": "OpenSCADA — open SCADA system in perspectives of 0.9LTS release"

The conference was a successful one. On the conference there read the report about perspectives a new LTS version 0.9.

Great thanks the FossLviv team!

Also big thanks Chopovskij Sergej for a related report to OpenSCADA!

The conference site is: conference.linux.lviv.ua

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.[more]

OpenSCADA adaption to work on OS Android


25.06.2017: Packs to an APK package, starts and works through JNI in commonly through the WWW. OpenSCADA main functions related to Qt restoring and fixing.

Due the adaption process touches the build system of OpenSCADA, for some users and developers it can be interesting in way of full-formatted adaptions to other OS, this is QNX or MS Windows about which on the forum they meant and some try.

If the function of working OpenSCADA on the Android OS is significant for you, you can help by sponsoring the task and then you will get usable and supported result some faster. Your help for the task will also motivate and consolidate other users and developers for adaption OpenSCADA on other OS and hardware environments!

Update 17 to the production release of OpenSCADA 0.8 LTS

The update 0.8.17 (12.02.2017) to the production release of long term support (LTS) targets to upgrade present installations of the production version for fix known for now problems and expand its to some improvements with operative services updates providing here for signed to the technical support service users. The update you can use for deploy new installations but for that better use The Work version (0.9) which provides more new features, modules, the component libraries and so on!

Generically the update fixed about 60 bugs and append some improvements:

  • API:
    • Changes:
      • SYS: More functions set to constant after some objects appending by a copy constructor.
        • TConfig::cfgChange() expanded by previous configuration value argument "pc".
        • TVariant: It's expanded in string type for STL-string using always except fields marked as "stdStringOmit", mostly for TCfg as a constant.
        • ...[more]

OpenSCADA expandings to direct work with the low-level buses and devices: 1Wire, I2C, GPIO

Low-level devices experiment in OpenSCADA

Raspberry Pi 2 and 3 boards were purchased as a platform for free access to low-level buses from Linux and OpenSCADA environments.

For allow to work with Raspberry Pi GPIO the OpenSCADA was expanded by new DAQ module BCM2835. For work with the bus I2C the OpenSCADA module Transport.Serial was expanded to I2C support. To provide a configurable fast access by the the static external functions call the DAQ.JavaLikeCalc module was expanded to the functions dynamic linking.

For working with the 1Wire bus there were developed RS232 adapters DS9097, DS9097U and created proper templates into OpenSCADA. Also the templates have included support of the different 1Wire chips: DS1820, DS1820/DS18S20/DS1920, DS1822, DS2413, DS2408, DS2450, DS2438.

I2C bus was tested on the Raspberry Pi boards for chips: PCF8591, PCF8574, DS3231, AT24CXX.

GPIO was tested for devices: DHT, 1602A.

Generic documentation of "Data acquisition in OpenSCADA" significant updated, appended and translated

Data acquisition in OpenSCADA

The documentation actualized to the current OpenSCADA state and trends, significant updated, appended and translated. The documentation described in details the new data sources redundancy mechanism.

Data acquisition of the SCADA (Supervisory Control and Data Acquisition)-system is its integral part, which get data from sources of different type. The nature of data, which operates SCADA, is characterized by signals of basic value's types (Integer, Real, Boolean and String). The signals vary over time and has their history, life. In the theory of technological processes (TP) under the signal it's meant the value of TP sensor in the ADC code, "raw" signal or in the real value. Signals can be combined into groups, which are often called parameters. For example, the advanced data sources can provide the structures of parameters with the predefined set of related signals. In addition to the direct data acquisition in the function of this mechanism is also included the transfer of actions to control devices of...
