Study Notes
Working Procedure of SCADA System
- SCADA (Supervisory Control and Data Acquisition) system includes data acquisitions, network data communication, information presentation, and monitoring/control.
- Key components involved:
- Sensors collect critical information.
- Remote Terminal Unit (RTU) sends data to controllers.
- Controller displays system status.
- Communication Network acts as the backbone for data transmission between central control and remote devices.
Data Acquisitions
- Real-time systems consist of numerous components and sensors to monitor operations.
- Critical to know the operational status; examples include sensors measuring water flow and pressure in reservoirs.
Data Communication
- SCADA uses wired networks for communication among users and devices.
- Internet communications are employed, with data transmitted via specific protocols.
Information/Data Presentation
- Real-time systems manage vast amounts of data via Human-Machine Interface (HMI).
- HMI allows the graphical representation of information from various sensors, enabling human interpretation and monitoring.
Monitoring/Control
- Operators can turn on/off devices from the control area using various switches.
- The SCADA system operates automatically but can require human intervention during critical situations.
Advantages of SCADA System
- Provides comprehensive mechanical and graphical information for operators.
- Easily expandable, allowing for additional control units and sensors as needed.
- Effective in managing operations during critical situations.
All About SCADA
- Advanced computer-based systems monitoring and controlling industrial processes across diverse sectors.
- Offers real-time operational insights for efficient decision-making.
- Enables remote monitoring and management from virtually any location.
- Plays a crucial role in industrial automation, facilitating applications like predictive maintenance and asset tracking.
Components of SCADA System
- Human Machine Interface (HMI): Acts as the system's brain; provides an intuitive graphical interface for operators.
- Remote Terminal Unit (RTU): Serves as a gateway, collecting and transmitting data from field sensors to controllers.
- Programmable Logic Controller (PLC): Processes data using programmable logic; controls industrial processes based on sensor input.
Historical Records
- Historical records track changes in variable values to reflect operational status.
- Collecting and analyzing historical data aids in optimizing productivity and quality in projects.
Configuration Software
- Types of records include:
- Timing Records: Track engineering variable changes over specified intervals.
- Trigger Records: Activate upon binding trigger variables for recording.
- Changing Records: Log changes in variable value.
Recording Configuration
- Database type includes file databases.
- Data storage locations include internal storage, SD cards, or USB drives.
- Automatic file creation occurs when data files exceed predefined sizes, ensuring efficient data management.
