The Sequential Function Charts (SFCs) define specific tasks. SFCs are made up of steps, transitions, and actions, and are most often used to perform sequential control. You define the task you want to perform by graphically representing the steps, transitions, and actions involved.
A sequence in an SFC is drawn as a series of steps, represented by boxes, and vertical lines representing the transition from one step to the next. Each step can contain a set of actions that affect the process. Once defined, the SFC can be executed.
None of the pre-engineered modules in the DeltaV system library have Sequential Function Charts because the sequences are specific to your application.
