Equipment selection:
● For unit selection without conditions
This list displays the existing areas and unit classes from the basic engineering for selection,
depending on the tree structure. The units available in each case are visible underneath.
Select the possible unit candidates here. The unit candidates limit the phases that can be
used during execution of this recipe unit.
● For unit selection with conditions:
All units are displayed as not modifiable under "Equipment selection". The units that are to
be selected have already been selected automatically.
Strategy:
You use the strategy to specify how one of the possible units is selected for the actual batch
execution:
● Preferred unit: If no other assignment is made before creating a batch, the unit specified
as the preferred unit is used for the batch.
● The longest out of use: The unit that has not been used for the longest time will be used.
● Operator selection: The assignment of the unit is performed manually by an input in an
operator dialog.
● Process parameters: The variable selected in the "Process parameters" field determines
the unit to be used.
Preferred unit:
You select the preferred unit for batch processing.
Process parameters:
You select the variable with the "Unit" data type that determines on a process-dependent basis
the unit to be selected during batch execution. With the button to the right, you open the next
dialog "Level/....". The interconnection of the process parameter can be checked and set here.
Start allocation:
If this check box is selected, the entire batch processing will start only if the unit required by
this unit recipe is free. This unit is allocated at the start of the batch even if the actual processing
begins later. Use this procedure to ensure the availability of the unit.
