1.2. SCADA systems

SCADA is an acronym that stands for Supervisory Control And Data Acquisition. SCADA systems serve as an interface between an operator and processes of all kinds, such as industrial machinery, automatic controllers and sensors.

SCADA systems can be anything from simple applications of sensing and controlling, to control panels in huge power plants, or control panels in centralized traffic control systems.

A typical SCADA system must provide communication drivers with various equipment, a system for continuous recording of data ("data logger") and a graphical user interface known as "HMI" or Human Machine Interface.
In a HMI graphics are available as buttons, icons and displays, representing the actual process being monitored or controlled.

Among some of the most commonly used functions in SCADA systems are:

Generation of charts and reports with historical data;
Detection of alarms and automated event logging;
Process control including remote sending of parameters and setpoints;
Drive and control equipment;
Use scripting languages to develop logical automation.

1.3. ScadaBR

ScadaBR is developed as "open-source" software. This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. http://www.gnu.org/licenses/.

All the documentation and the source code of the system is freely available. It is allowed to modify and re-distribute the software.

ScadaBR is a Java based application. PCs running Windows, Linux and other operating systems can run the software, this is done via an application server (Apache Tomcat is the default choice).

When you run the application, it can be accessed from a web browser, preferably Firefox or Chrome. The main interface of ScadaBR is easy to use and offers visualization of variables, graphs, statistics, protocol configuration, alarms, construction of HMI screens and a number of configuration options.

After configuring the communication protocols with the equipment and the variables set (inputs and outputs, or "tags"), you can build operator interfaces using the web browser itself. You can also create custom applications in any modern programming language from the source code available or via its API "web services".

On our site you will find a demonstration video with examples of the basic features of ScadaBR: http://www.scadabr.org.br/.
