Sequential Function Chart (SFC)

A Sequential Function Chart (SFC) is a visual tool used in automation and control systems to represent processes that happen in a specific order. It uses diagrams with steps (called "actions" or "states") and transitions (connections) to show how a system progresses from one stage to another. Think of it like a flowchart that guides the operation of machinery or processes, ensuring they run smoothly and in the correct sequence. SFCs help engineers design, monitor, and troubleshoot complex control systems by providing a clear, organized way to understand sequential operations.
