What is another name for a decentralized control system (DCS)?

• Centralized control system

• Distributed control system

• Autonomous control system

• Independent control system

In a decentralized control system, where are the control functions located?

• In a single central unit

• Across multiple autonomous units or nodes

• Outside the system

• In a central database

What is the main advantage of decentralized control systems in complex environments?

• They require less maintenance

• They are cheaper to implement

• They offer greater scalability and flexibility

• They use less energy

How do units in a decentralized system operate?

• They operate based on a central command

• They operate independently and are responsible for a specific segment or function

• They do not communicate with each other

• They follow a pre-defined path without any adjustments

Why are decentralized control systems particularly advantageous in large manufacturing plants, power generation and distribution networks, and transportation systems?

• They are easier to shut down

• They are designed for simple operational conditions

• They adapt effectively to changes and ensure continuous and efficient process management

• They require a lower degree of specialization

What is a Distributed Control System (DCS) used for?

• To manage and control simple industrial processes

• To manage and control complex industrial processes

• To manage communication networks only

• To distribute control functions in a centralized manner

In a centrally controlled system, how is control typically managed?

• By multiple entities or components

• Through a central hub or controller

• Directly between components

• Using a distributed communication network

How does communication occur in a distributed system?

• Through a central hub or controller

• Directly between components

• Only within specialized controllers

• By a single entity or component

Which system tends to be less complex?

• Distributed system with many interactions between components

• Centrally controlled system with a clear hierarchy of control

• Distributed system with a central hub for communication

• Centrally controlled system with distributed control functions

Which type of system tends to be more fault-tolerant?

• Centrally controlled systems

• Distributed systems

• Both are equally fault-tolerant

• Neither is fault-tolerant
