Sequential Function Charts represent a sequence of Logic. They allow you to create a Logic program that defines system behavior that occurs in steps, depending on specified conditions.
One of the main advantages of Sequential Function Charts (SFCs) is that only the active parts of the SFCs are executed, and you can easily see which parts are inactive. This means it is easy to determine what condition caused a step to occur.
The following sections explain the basic concepts of Sequential Function Charts and explain how to set up an SFC:
- Sequential Function Chart Components
- How Sequential Function Charts Work
- Simultaneous Sequences

- Define a Step as the First Step in a Sequential Function Chart
- Add a Transition to a Sequential Function Chart
- Edit a Transition
- Display the Actions Tab on a Sequential Function Chart
- Add an Action to a Sequential Function Chart
