The way a PLC organizes its memory is called a memory _____.

• A. Map
• B. Grid
• C. Layout
• D. Bank

Answer: (A)

Memory map is the way a PLC’s memory is organized and accessed. It defines how the processor’s address space is partitioned into regions for inputs, outputs, internal memory, timers, counters, data blocks, and other data. This map tells you where each type of data lives and how to address it during the program’s scan, ensuring that when you reference an input, a coil, or an internal flag, you’re reading or writing the correct spot in memory. Why this term fits best: it captures the idea of a defined, fixed layout of memory addresses that the PLC uses to map real-world I/O and data into the program. Other terms like grid, layout, or bank describe general arrangements or smaller subsets, but they don’t convey the complete, addressable organization of the PLC’s memory space in the way a memory map does.
