In the world of industrial control, serve as a critical tool for organizing complex logic. Unlike standard text-based programming, SFC is a graphical language that represents processes as a series of steps and transitions. This structure is essential for modern manufacturing, where timing and sequence are as important as the code itself. The IEC 61131-3 Standard

Rectangles representing specific states of the process (e.g., "Wait," "Close Door"). In the world of industrial control, serve as
Specific tasks associated with a step, such as activating a motor. The IEC 61131-3 Standard * 5590 Controllers
The was established to provide a unified framework for Programmable Logic Controllers (PLCs) . It abstracts vendor-specific differences by offering five core languages, ranging from graphical tools like Ladder Diagrams to textual ones like Structured Text. SFC is unique within this group because it functions as a higher-level organizational language. It allows engineers to partition a program into logical units, making the entire system easier to troubleshoot and maintain. Structure and Execution An SFC consists of three primary components:
