Siemens SIMATIC BATCH Operating Manual page 501

The structure of a flat recipe can be edited into approximately twenty levels by using
substructures.
Synchronization
Using the synchronization functions, you coordinate the execution of recipe chains. In flat
recipes, synchronization in sequences of the same simultaneous branch are possible.
At each synchronization point, you decide whether or not the chain is halted. If you select
"Blocking", the chain waits until the other chains involved have reached the synchronization
line or had already reached it (may have already continued). If "Blocking" is not selected, the
chain does not wait for the other chains. The fact that the synchronization point was reached
is still recorded.
