**Sequential Function Charts**

What is Sequential Function Charts?

Sequential Function Chart (SFC) is a graphical programming language used for programmable logic controllers (PLCs). It's based on a state machine model and is particularly well-suited for describing sequential and parallel control logic. SFC consists of steps, transitions, and actions. Steps represent a specific state of the system, transitions define the conditions for moving from one step to another, and actions are operations performed while a step is active. SFC is commonly used in industrial automation to control complex processes and machinery.
