SCADA Systems Flashcards
These systems are highly distributed systems used to control geographically dispersed assets, often scattered over thousands of squared kilometers, where centralized data acquisition and control are critical to system operation.
SCADA - Supervisory Control and Data Acquisition Systems
What are the 3 generations of SCADA?
Monolithic
Distributed
Networked
Non-networked SCADA system , stand alone, proprietary systems, redundancy accomplished through two identically equipped mainframe systems, a primary and a backup, connected at the bus level.
Monolithic SCADA Systems
This generation of SCADA systems took advantage of developments and improvement in system miniaturization and LAN technology to distribute the processing across multiple systems.
Distributed SCADA Systems
This current generation of SCADA Master Station architecture is closely related to that of the second generation, with the primary difference being that of open system architecture rather than a vendor controlled, proprietary environment.
Networked SCADA Systems
These are used to control industrial processes such as electrical power generation, oil refineries, water/waste water treatment, and manufacturing production.
Distributed Control Systems (DCS)
This type of control system that has been used extensively for large high rise office buildings, hotels, aw well as multi-building complexes typical of a campus/installation environment..
Energy Management and Control Systems (EMCS)
This system describes the functionality provided by the control systems of a building. The core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, monitors system performance, alarms and security, device failures and provides notification to staff. Often referred to as an intelligent building system.
Building Automation System (BAS)
