SISTEMA SCADA

SCADA stands for Supervisory Control And Data Acquisition (Supervisory Control and Data Acquisition) is a computer software that allows you to control and monitor industrial processes remotely. Provides real-time feedback to the field devices (sensors and actuators), and controls the process automatically. Provides all the information generated in the production process (monitoring, quality control, production control, data storage, etc.) and allows management and intervention. 

Feedback, also called feedback or feedback is an organization, the process of sharing observations, concerns and suggestions, with the intention of gathering information, individually or collectively, to improve or modify various aspects of the functioning of an organization. The feedback has to be bidirectional so that continuous improvement possible in the hierarchical ladder, top-down and bottom up. 

In control theory, the feedback is a process by which a certain proportion of the output signal of a system is redirected back to the entrance. This is often used to control the dynamic behavior of the system. Examples of feedback can be found in most of the complexes, such as engineering, architecture, economics, sociology and systems biology. Arturo Rosenblueth, a Mexican researcher and physician whose 1943 seminar gave a presentation called "Behavior, Purpose and Teleology" ("Behavior, purpose and teleology"), according to Norbert Wiener, set the foundation for the new science of cybernetics and proposed controlled by negative feedback, behavior applied to an animal, to human beings or machines and was a key guiding principle in nature or human creations ..
