General-purpose PLCs are designed to perform a wide range of control tasks, programmed to execute complex control logic and interact with multiple I/O points, making them versatile controllers in industrial automation.

In contrast, smart field devices (like smart transmitters or actuators) are typically dedicated to specific measurement or control functions and may have embedded intelligence for self-calibration, diagnostics, or simple control, but with a more limited purpose and function (C).

(A) is incorrect because smart field devices often can be managed remotely.

(B) is true but not a differentiating functional characteristic.

(D) is incorrect; smart field devices often have configurable logic or settings.

GICSP training differentiates these device classes to tailor cybersecurity controls effectively.
