Example of a hierarchical recipe
The following figure uses a color visualization to show the execution of a control recipe with a
typical hierarchical recipe structure. The entire control recipe is shown in the central window
and the right-hand window shows the execution of a recipe operation. This recipe operation
is only given the status "completed" when the synchronization is complete.

SIMATIC BATCH uses so-called equipment phases (EPE, Equipment Procedural Elements)
for the recipe sequence. This can be of the type EPH or EOP.
To ensure problem-free cooperation with the overlying control, the equipment phase must
provide the following main states (final states), the transitional states are optional and not
absolutely necessary:
