12.8.3 How do I configure conditions for the unit allocation?
Unit parameters dynamically define the properties of units. Setpoints are transferred to the
units and the actual process values are queried. When a unit is allocated, the process values
of possible units are queried in a transition via batch control.
Description of configurations
Two reactors serve as an example. Depending on their dynamic properties, one of the two
reactors is to be allocated for further batch execution. A condition is configured in a
corresponding master recipe for this purpose.
Requirements
● Parameters from batch control or the process, e.g., probe, are passed dynamically to the
units available for selection. In our example, the value of the input "UnitStatus" is set to
"Clean" at reactor R501 and the value at reactor R502 is set to "Dirty".
● The corresponding IEPAR parameter blocks have been configured at the possible units.
● All engineering data have been compiled and downloaded and available updated in
BatchCC.
