Understanding SCADA Systems

What is SCADA?

• SCADA is a programming language for web development.
• SCADA is a type of software for personal computers.
• SCADA is a hardware device used for gaming.
• SCADA is a system for monitoring and controlling industrial processes.

What is a SCADA used for?

• SCADA is used for financial auditing.
• SCADA is used for social media management.
• SCADA is used for personal fitness tracking.
• SCADA is used for monitoring and controlling industrial processes and infrastructure.

How does a SCADA work?

• SCADA systems monitor and control industrial processes by collecting data from sensors, transmitting it to a central system for analysis, and allowing remote control through a user interface.
• SCADA systems operate solely on manual input without automation.
• SCADA is primarily used for financial transactions and banking.
• SCADA systems only collect data without any control capabilities.

What were the problems industrial organizations were trying to solve before SCADA was introduced?

• Inefficient monitoring and control of industrial processes.
• Limited production capacity.
• Excessive labor requirements.
• High costs of raw materials.

What is the difference between PLC and SCADA?

• PLC and SCADA are both types of programming languages.
• PLC is used for data storage; SCADA is used for programming logic.
• PLC is a software tool for data analysis; SCADA is a hardware device for automation.
• PLC is a hardware device for automation; SCADA is a software system for monitoring and control.

What kind of data does a SCADA system collect?

• Temperature, pressure, and speed data

• Only historical data

• Only live data

• Data from human operators

What is the primary function of a PLC?

• To monitor the state of inputs and control outputs

• To store historical data

• To provide a user interface for operators

• To communicate with SCADA systems

What are the four main components of a SCADA system?

• Field Instrumentation, RTUs, Communication Infrastructure, HMI

• Sensors, Actuators, PLCs, RTUs

• Data storage, Data analysis, Control mechanisms, User interface

• Inputs, Outputs, Control systems, Monitoring systems

What is the role of the Human-Machine Interface (HMI) in a SCADA system?

• To provide visualizations of the system’s status

• To collect data from sensors

• To execute control commands autonomously

• To store historical data

What is the purpose of the communication infrastructure in a SCADA system?

• To enable data transmission between devices

• To store data collected from sensors

• To provide a user interface for operators

• To execute control commands
