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.

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...

Module "DBArch" of subsystem "Archives" significant expanded

Archive.DBArch

The module expanded to grouped values archivation and set optimal significantly for the archives reading by the pre-loading extension of seek request of DB. The module documentation updated and translated.

The module designed for archiving messages and values of OpenSCADA to a database maintained by OpenSCADA.

On 17 September 2016 in city Kiev (Ukraine): The conference of developers and users of the free software — FOSS 2016: "OpenSCADA — achievements, perspectives and 0.9LTS plans"

The conference was a success. On the conference was read the report about achievements, perspectives and 0.9LTS version plans of the project OpenSCADA.

Great thanks for OSDN!

The conference site is: osdn.org.ua

During the last three years the project OpenSCADA continued in self progress into the mode of deep stability with elements of expanding the allowed functions and it's directing to perform conditions and tasks of releasing a new stable version 0.9, there was done firstly of the OpenSCADA own server deploy, the project's resources planed update and creation of new services. Into the report shows the significant progress at the last three years and the now implementing plans, and the nears future plans.[more]
