Function Block

A function block is a modular unit in automation systems that encapsulates a specific function or process. Think of it like a customizable, self-contained "recipe" that takes in inputs, processes them according to predefined logic, and produces outputs. This enables engineers to build complex control systems by connecting multiple function blocks, much like assembling building blocks. They promote reusability, easier maintenance, and clearer organization within automation software, making control systems more efficient and adaptable.
