Function Block Diagram (FBD)

A Function Block Diagram (FBD) is a graphical way to design and understand control systems, often used in industrial automation. It represents the functions of a system—like sensors, controllers, and actuators—as interconnected blocks. Each block performs a specific task, and lines between them show how they interact or share information. FBD makes it easier to visualize complex processes, ensuring that components work together efficiently. It is commonly utilized in programming programmable logic controllers (PLCs) to automate machinery and processes.
