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.
