Transition placeholder

Incomplete structures must be supplemented dynamically in order to be syntactic and complete
at any time. The recipe editor therefore automatically inserts placeholders recipe phases and
transitions.
A transition placeholder has the appearance of an empty transition.
To convert a transition placeholder to a transition, simply double-click on symbol, or insert a
transition into the placeholder via the "Insert" menu or the toolbar.
10.3.3.11

Command step

A command step transfers a command (S88 command) in the recipe operation to one or more
target recipe elements (RPEs). It is also possible to specify the status that the target object
needs to have before it can receive the command. This status filter applies to the entire list of
target recipe elements. A setpoint runtime you have determined for the equipment phase can
also be specified. This means that the equipment phase will end only when the setpoint runtime
has expired.
10.3.3.12

Parameter step

A parameter step is a recipe element in which parameter values are transferred to a unit. Unit
parameters are queried in transitions within a recipe and corresponding units are allocated as
a result.
10.3.3.13

Simultaneous branch

A simultaneous branch consists of at least two horizontally arranged sequences joined at top
and bottom by double lines.
How it works
A simultaneous branch leads to simultaneous processing of several sequences. This allows
processes to be executed at the same time.
With simultaneous branches, the branches are processed only if the first equipment phase
can use all branches. Once it is released for Batch, the equipment phase can then be allocated,
regardless of whether it is in automatic or manual mode. An equipment phase can only be
started by Batch if it is the automatic mode.
Synchronization lines
Another method of coordinating sequences is to create synchronization lines (Page 515)
between the recipe steps.
10.3.3.14

Alternative branch

An alternative branch consists of at least two vertically arranged sequences joined at top and
bottom by a single horizontal line.
