What is a Distributed Control System (DCS)?

• A manual system for industrial processes

• A computerized system that automates industrial equipment in continuous and batch processes

• A system exclusively for power management

• A standalone control unit without networking capabilities

Which type of control system has no feedback mechanism?

• Closed loop system

• Feedback control system

• Open loop system

• Automated control system

What is a transfer function in control systems?

• The physical transfer of control from one system to another

• The mathematical relation of the input and output of the control system

• The transfer of data between networks

• The conversion of analog to digital signals

What is the primary function of ballast management systems in maritime DCS?

• Only controlling engine speed

• Managing cargo loading

• Monitoring water levels and pressure in ballast tanks

• Controlling fuel consumption

In traffic light control systems, what makes it an open loop system?

• It operates based on predetermined timing without feedback

• It always responds to traffic conditions

• It has continuous feedback from sensors

• It adjusts timing based on traffic flow

What is the purpose of a flow transmitter in DCS?

• To control electrical current

• To measure and convert flow rates into electrical signals

• To store fluid in the system

• To regulate pressure only

What distinguishes a closed loop system from an open loop system?

• The presence of feedback control

• Lower operational costs

• Simpler design

• Manual operation capabilities

What is the primary function of a SCADA system?

• To provide entertainment content for industrial workers

• To monitor and control industrial processes through computer-based systems

• To manage human resources in manufacturing plants

• To handle financial transactions in industrial settings

What is the primary purpose of Human-Machine Interfaces (HMIs) in SCADA systems?

• To store historical data

• To collect data from sensors

• To transmit data between networks

• To allow operators to monitor and control equipment in real time

In maritime applications, what is one of the primary uses of SCADA systems in engine room monitoring?

• Managing crew schedules

• Monitoring critical engine parameters like temperature, pressure, and vibration

• Controlling entertainment systems

• Managing passenger manifests
