PLC and PAC Quiz

What does PAC stand for in the context of industrial control systems?

• Programmable Automation Controller

• Personal Automation Computer

• Programmable Application Control

• Personal Application Controller

What type of execution does a PLC mix?

• Scan-based and event-driven

• Time-based and logic-driven

• Signal-based and data-driven

• Process-based and vision-driven

What does a Programmable Automation Controller (PAC) combine?

• A PC and a smartphone

• A PC and a PLC

• A PLC and a microcontroller

• A PLC and a sensor

What does a PAC replace in terms of control systems?

• Modern, easy-to-modify, secure systems

• Old, costly, difficult-to-modify, less secure proprietary DCS systems

• Simple, inexpensive, open-source systems

• New, efficient, user-friendly systems

What is a Programmable Automation Controller (PAC)?

• A single processor-based device

• A two- or more processor-based device like a personal computer

• A device used only for single machines

• A device that cannot be networked

Why is a PLC considered better for certain applications?

• It is more expensive and complex

• It is easier to use, maintain, and modify, and less expensive

• It is only used for networking

• It is used for data distribution only

What is a PAC better suited for?

• Single machine control

• Creating industrial control systems for multiple machines and processes

• Only for data storage

• Non-networked applications

What factors should be considered when selecting a control system like PAC, PLC, or IPC?

• Only budget and size

• Budget, size, support, complexity, and future expansion

• Only support and complexity

• Only future expansion
