Supervisory Control and Data Acquisition (SCADA) is a control system architecture used in various industries to monitor and control processes, infrastructure, and facilities. SCADA systems are commonly employed in sectors such as manufacturing, energy, water and wastewater treatment, transportation, and more. The primary purpose of SCADA is to gather real-time data from sensors and equipment in the field and provide operators or control systems with the ability to monitor, control, and analyze industrial processes.
Key components and features of SCADA systems include:
SCADA systems have graphical interfaces that provide real-time data visualization, allowing operators to monitor the status of industrial processes. HMIs are designed to be user-friendly and display information in a clear and understandable format.
SCADA systems enable supervisory control, allowing operators to intervene and control industrial processes based on the information gathered from sensors and devices. This can include starting or stopping equipment, adjusting setpoints, or triggering alarms.
SCADA systems acquire data from various sensors, meters, and instruments distributed throughout the industrial environment. This data can include parameters such as temperature, pressure, flow rates, and other relevant variables.
SCADA systems rely on communication networks to transmit data between the field devices and the central control system. This can involve wired communication (such as Ethernet) or wireless technologies, depending on the application.
SCADA systems implement control logic to automate processes based on predefined rules and algorithms. This logic helps optimize operations, improve efficiency, and respond to abnormal conditions.
Security is a critical aspect of SCADA systems due to their connection to critical infrastructure. Security features include user authentication, access control, encryption, and measures to protect against cyber threats.
SCADA systems can integrate with other enterprise-level systems, such as Manufacturing Execution Systems (MES) or Enterprise Resource Planning (ERP) systems, to provide a holistic view of operations.
To ensure system availability and reliability, SCADA systems may incorporate redundancy at various levels, including communication links, servers, and power supplies.
