If one of the above icons for an operator prompt is displayed within a control recipe element,
the batch execution is interrupted and an operator action is required from you to resume the
batch. Right-click on the corresponding control recipe element and select the appropriate
command in the shortcut menu:

Additional status identifier - internal waiting, waiting for external synchronization and pause after step
A step that is waiting for an internal event is is indicated with an hour glass. Example: Step
waiting for free data blocks for SIMATIC BATCH AS based.
The Synchronization line shows that the step is waiting for external synchronization (from MES
via API, for example).
Steps that have performed a pause after step are indicated with the command symbol for
"Pause after step".
Additional status identifiers - group display for container objects
A batch step consisting of lower-level batch steps (recipe unit, recipe operation or
substructure), is referred to as a container step. The status of such container steps is
determined by the status of its lower-level steps. To indicate that individual sub-objects have
interrupted the execution, there are group displays for container steps:
A sub-object blocks the execution when it is stopped, aborted, held or paused after a step. A
sub-object waits for external synchronization. A sub-object demands operator input in manual
mode for an operator dialog, unit selection, electronic signature or when a breakpoint is set.
