10.4.4 Unit allocation
10.4.4.1 Assignment of the unit with a flat recipe
The units are specified individually in the object properties for each recipe step. The unit
assignment is made according to the structure of the plant hierarchy in the engineering system.
This means that when additional levels were added to the three-level batch hierarchy, for
example an area level between process cell and unit, these are also available as selection
criteria in the unit assignment to help make the hierarchy clearer.
If you do not use the "Process cell optimization with online assignment of a unit (Page 529)",
follow the steps outlined below.
Assignment of the unit with/without conditions?
● If you want to select the units without conditions, follow the procedure described in this
section.
● If you want to select the units with conditions, follow the steps outlined in the section "Unit
selection via conditions for a flat recipe (Page 526)".
Procedure in the BATCH Recipe Editor
1. Open the recipe.
2. Select a recipe step.
3. Select the "Properties" command in the shortcut menu (selected with a right-click).
Select the "New assignment" button.
The "Allocations" tab appears.
4. First, select the representation of the tree structure:
– Class view: All unit classes without area structure will be listed in the "Unit selection"
field.
– Process cell complex view: All areas with the subordinate units are listed in the "Unit
selection" field.
5. Select the unit class in the "Device selection" field and deselect those units (unit candidates)
that are not suitable for this recipe unit procedure.
The unit classes and units from the basic engineering are available for selection. By
selecting a unit class and then deselecting the unit candidates, you limit the phases that
can be used in the execution of this unit recipe (displayed in the "Available phases" field).
6. If necessary, select a preferred unit in the "Preferred unit" field.
If no other assignment is made before creating a batch, the unit specified as preferred is
used for the batch execution.
7. Confirm the selection with "OK".
