Summary of the main requirements:
● If there is a maximum of one block instance per phase or operation type per unit in all
available units, the entire batch process cell is in type mode.
● If there is more than one block instance per phase or operation type in at least one unit,
the entire batch process cell is in instance mode.
● If the corresponding requirement is met, the system switches internally from type mode to
instance mode and vice versa.
● You can only configure more than one instance per type in a unit for SFC types. The
instance mode is therefore only possible with SFC types. This is also true for a mixed type
configuration, which means multiple instances are only possible with SFC types.
● The instance mode is not possible with pure (I)EPH types or even with BATCH flexible
V4.02 blocks.
Selecting a standard instance in the BATCH configuration dialog
If there are several instances of the same SFC type within a unit, one instance is selected as
the default instance in the BATCH configuration dialog. To do this, use the "Default instance"
row for phase and operation types and select a block instance name from the drop-down list.
The selected default instance is given preference when creating recipes.
If the configuration engineer does not select a default instance, one of the possible default
instances is automatically selected when the Batch types are generated. If the selection is
made manually, this is always retained and can be changed or reset at any time so that the
selection is once again made automatically.
In the BATCH configuration dialog, the following is checked:
● If there are multiple instances within a unit: Is the block instance name unique? Error
message: Multiple instances with the same name within a unit are not permitted.
● If there are multiple instances within a unit: Has a common block instance name been
assigned in all other units where this SFC type is used?

Unit 2 Remark
DosiU2 Both units already include one instance each for the Dosing type.
HeatU2 Both units already include one instance each for the Heat type.
AgitU2 Both units already include one instance each for the Agitation type.
Unit 2 Remark
DosiU2 Both units already include one instance each for the Dosing type.
HeatU2 Unit 1 has two instances for the heat type; unit 2 has one instance.
Agit1U2 Unit 1 has three instances for the Agitation type; unit 2 has two instan‐
ces.
