How it works
With alternative branches, you can adapt the execution of the recipe to states in the process.
The conditions in the top transitions of the sequences decide which sequence is executed.
10.3.3.15 Synchronization line
The synchronization lines coordinate the execution of recipe sequences in the units or of the
recipe operations (ROPs) between the units.
10.3.3.16 Synchronization point
In each synchronization point, you can decide whether execution is continued or halted.
10.3.3.17 Monitoring
Process events can be monitored as well as a defined area of a recipe (monitoring area).
A transition condition at the start monitors process values, states and events. When the
transition condition is fulfilled, the monitoring runs concurrently. Monitoring is configured similar
to all recipe structures and can contain all the topological elements (loops, AND, OR,
synchronization lines, etc.).
10.3.3.18 Transition
Along with the step, a transition is a second element type used in structuring a recipe. It
contains the step enabling conditions between the steps.
10.3.3.19 Loop
A loop consists of a sequence with at least one recipe step and a return path with a transition.
Meaning
The loop allows multiple iterations of a sequence structure.
The transitions following the loop and in the return path decide how often the sequence is
repeated. If the condition in the transition following the loop is satisfied, control exits the loop.
The conditions of the two transitions should be mutually exclusive so that it is not the order in
which the transitions are evaluated that is relevant but rather the logic itself.
10.3.3.20 Jump
A jump is a recipe transition with or without a jump destination.
A recipe jump in a recipe level (RUP) skips a step in the sequential processing and resumes
at a defined recipe step. The currently running RUP/ROP/SUB ends at a location where no
jump destination is configured for a jump. The recipe jump is only executed if the configured
step enabling condition (transition) is fulfilled.
