SFC Elements

The Chart

The chart itself is a grid of cells upon which elements are placed. There are just a few types of elements available to these charts, but they can be combined in complex ways to create whole processes and production flows that are easy to read. Often these charts get quite large because of the complicated rules that are required for the type of processes the SFCs are used for. In this section you will see the basic elements that make up every chart. For more information about putting them together, see SFCs in Action.

The chart has some configuration that can determine how and when the chart is started up, as well as opportunities to respond to chart lifecycle events with scripting, such as onStart, onStop, onCancel, and onAbort, see Chart Lifecycle for details.
