A function-block diagram is an alternative method for programming what?

• A. Power transformers
• B. Programmable logic controller
• C. Power distribution systems
• D. Electrical motors

Answer: (B)

A function-block diagram serves as a graphical programming method specifically designed for creating logical sequences and control functions, particularly in programmable logic controllers (PLCs). In this context, function blocks represent specific functions, such as timers, counters, logic operations, or data manipulation tasks, allowing programmers to visualize and structure the automation process more intuitively. Using function-block diagrams makes it easier for technicians and engineers to understand and troubleshoot control systems, as the visual representation allows for better clarification of how different components interact. This method aligns seamlessly with the modular nature of PLC programming, where discrete functions can be combined to achieve more complex operations. Other options, such as power transformers, power distribution systems, and electrical motors, do not utilize function-block diagrams in their programming and operation, as these components do not inherently involve programmable controls or require the same type of logical sequence representations used in PLC environments.
