Interrupting a recipe
To resume a recipe at a different point, no other steps may be active within a step sequencer.
These steps can be deactivated in SIMATIC BATCH as follows:
● Abort step or stop step
A step is aborted or stopped with the menu command of the same name.
In the "Abort step" dialog, the following buttons are available:
– Abort step
– Abort batch (except conti.)
In the "Stop step" dialog, the following buttons are available:
– Stop step
– Stop step (except conti.)
● Allow step to run to end
To do this, set a breakpoint at the successor step and wait for the step to run to the end.
You can use the corresponding menu command to complete steps in the "ready to
complete" state.
Resuming a recipe at a different point
Select the "Start step" menu command to skip (forward jump) or repeat (backward jump)
sections of recipes based on the selected step. In the case of a backward jump, steps that
have already been run through are automatically reset (and, therefore, enabled) after the start
command. In the case of a forward jump, however, you must set preceding steps to this state
yourself. Before starting a step you must ensure that no more steps will be allocated or active
in the RUP concerned, nor will any more breakpoints be active. Please note:
● Releasing allocated steps
After steps are stopped or aborted, they usually remain allocated and, therefore, must be
reset. With the new project setting "Release recipe element after stop/cancel", the release
occurs automatically directly after aborting or stopping.
In this case, however, it should be noted that the aborted or stopped recipe elements retain
the status "aborted" or "stopped" in the control recipe although the corresponding recipe
phases were released in the background and thus in the automation system and therefore
have the "inactive" status as can be seen in the corresponding faceplates in OS Runtime.
● Deactivating breakpoints
To deactivate an active breakpoint, you only need to reset the step concerned. Caution:
Removing an active breakpoint starts the step.
You can use the "Start step" menu command not only for inactive steps but also for completed,
stopped or aborted steps. This means that it is possible, for example, to abort and restart a
unit recipe without the unit being released in between.
As a precautionary measure, when the start command is selected, SIMATIC BATCH checks
whether there are active recipe elements before and after the start step and lists any it finds
in a note box.
