Function Block Diagram

A Function Block Diagram (FBD) is a graphical way to represent complex systems or processes, commonly used in engineering and automation. It uses blocks to symbolize different functions or operations, which are connected by lines representing the flow of information or control signals. Each block performs a specific task, making it easier to visualize and understand how different parts of a system interact. FBDs are particularly helpful in programming programmable logic controllers (PLCs) in industrial settings, allowing engineers to design and troubleshoot systems effectively.
