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...

Automation Linux distributive on OpenSCADA

Live/Install/Service disk

The Automation Linux distributive on OpenSCADA moved to Debian packages base and described into proper project.

Of while for the project OpenSCADA was needed to create specialized builds of Linux environments kind of PLC firmwares, Live and installation disks for Automatic Work Places (AWP) and rapid familiarization of the OpenSCADA program. In begin it was enough to use standard Linux repositories, firstly it was ALTLinux and currently it is Debian. But in reason of needs to some packages of the Linux distributive fix, update and rebuild there was created self repository of this packages together with OpenSCADA packages.

OpenSCADA internet resources moved fully to new project's server and internet channel

OpenSCADA resources new hosting.

OpenSCADA project's all internet resources were moved to new self-project hosting and wider internet channel and domain name "oscada.org" was switched to it. Primarily the resources are: the WEB-site, WIKI-knowledge base, File-resources, EMail and repository of source codes.

Also for next the server's infrastructure of OpenSCADA project represents, traces and manages the proper project's page was created in the location.

From begins the OpenSCADA resources hosted on a main server of DIYA Ltd. From 2015 year the OpenSCADA project had own a server and an internet channel thanks mostly to Beams&Plasmas funding.
