SCADA SYSTEMS
1. INTRODUCTION Nowadays, the technological advances make possible a huge development in the industry and the improvement of control processes. The market demands make more and more important the remote acquisition of plant process data. No doubt, the key to achieve these requirements is the processes automation. “Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services”1 Automation has made the information more reliable and has created more efficient processes. SCADA Systems are part of Automation Pyramid. SCADA is an acronym for Supervisory Control and Data Acquisition. These systems are used to monitor and control a plant or equipment in industries. SCADA systems have been around since the 1960s and have evolved as technology changes. Actually, SCADA system is something every plant needs in ever‐changing world of automation technology. It has become an important tool in operation, monitoring and management of every industrial process, giving the operators information in real time that includes alarms view, remote control and logging of critical process data.

2.1. Overview The term SCADA refers to centralized systems which monitor and control entire sites or complex systems, usually from an industrial plant. Most control actions are performed automatically by RTUs or by PLCs. Host control functions are usually restricted to basic overriding or supervisory level intervention.2 SCADA provides integrated hardware/software solutions for supervision of industrial plants, for acquisition and processing of production data, for quality control of production and storage processes, for remote control of public utility networks or for building ...
