What does PLC stand for?

• A. Programmable Local Controller
• B. Programmable Logic Controller
• C. Process Logic Controller
• D. Power Line Controller

Answer: (B)

The main idea is recognizing the standard expansion of the acronym PLC. PLC stands for Programmable Logic Controller. It’s a rugged, industrial-grade computer used to automate machines and processes by reading inputs from sensors, running a user-created program that implements logic to decide what outputs to set, and then driving actuators like motors or valves. The term “programmable” means you can change the logic without rewiring, and “logic” emphasizes decisions based on logical conditions, timers, and sequences. This is why it’s the best answer. The other options aren’t standard terms in industrial automation—Programmable Local Controller, Process Logic Controller, and Power Line Controller refer to different concepts and aren’t the common designation for this device.
