What is scada system?
SCADA is an acronym for Supervisory Control and Data Acquisition. The key word in the term is supervisory. This indicates that decisions are not directly made by the system. Instead, the system executes control decisions based on control parameters entered by the engineer. The system monitors the process & generates alarm notifications when conditions are out of tolerance. Another significant task of a SCADA system is Data Acquisition. Information gathered by the system is available to user, in order to evaluate the effectiveness of operations. This information is available in real-time, and archived for review.
