Packaging cycle SFC

This SFC shows a simple packaging cycle as four active phases. The machine waits idle, feeds a product, closes the sealer for a timed interval, and discharges the package. Transitions use the signals that confirm progress through the machine. The chart supports design discussions because it exposes the intended order of operations, while a working machine program also requires equipment-specific safety and fault logic. Before using the layout in a build or document, compare every label with the source requirements and update the drawing when parts, conditions, or materials change. The example is deliberately small so the essential relationships remain readable, easy to review with collaborators, and ready to extend with the details required for the actual project.
