Active automation functions and transition are shown by a run marker (").
These can be set or removed when the AFs or transitions are paused. When
control recipe execution continues, those automation functions and
transitions are activated which have a run marker at this point in time.
With the automation functions the setpoint values (AF parameters) can be
displayed even while a batch is executing. When you carry out the detailed
planning of the AF you can specify a maximum of 3 parameters for
visualization. You cannot make the input for visualization unless the batch
has already been paused and ’Change’ selected.
The actual values of the parameters are shown in the transition dialog next to
the operands.
A substructure itself does not have any status as such, although the objects it
contains each have a status. When steps which contain substructures are
visualized, the states of the automation functions and transitions contained in
this substructure are taken into account. Here the individual states (which
will normally be different) are shown ORed with a definite priority.
Target step selection is only possible when the batch is in the ’paused’ state.
When selecting the target step, the qualifier can specify where recipe
execution should be continued.
The procedure is as follows:
1. Pause batch
2. Select one or more active objects (automation functions or transitions)
and remove the run markers from them (menu ’Controller’ ––> Remove
run marker).
3. Select one or more objects which are not as yet active and set run markers
for them (menu ’Controller’ ––> Set run marker).
Steps 2 and 3 are also possible within substructures.
Automation functions which are running will still be processed but their
successors will now be ignored. Active transitions will be ignored with
immediate effect.
