Hierarchy folder "Unit"
Several units can be defined in one process cell. Several units can be used within a master
recipe. Examples at this level could be the division of a process cell into neutralization,
extraction, distillation, or preparation.
Predecessor/successor
In the object properties of the "Unit" hierarchy folder, you can select a different unit of the same
project, or of a different project as successor for each unit. If this successor is located in another
project, it is displayed in the current project as a hierarchy folder with a link.
You can open this dialog from the object properties dialog of the hierarchy folder Unit > "S88
type definition" tab > Predecessor/successor button.
Managing unit allocation with UNIT_PLC
To map the unit on the programmable controller, there is exactly one instance of the BATCH
interface block UNIT_PLC in one of the charts of the "Unit" hierarchy folder. The batch control
enters the batch ID and the batch name in the UNIT_PLC block so that the allocation of units
can be managed.
With suitable user configuration on the AS, UNIT_PLC can be used to prevent the use of a
unit by batch control (input BA_EN: Batch enable).
7.1.3.7 "Equipment module" hierarchy folder
Introduction
Below the unit, create the hierarchy folder of the "Equipment module" object type:
● If the equipment folder is created directly below the unit folder, the "Equipment module"
object type is assigned automatically by the system when it is created.
● If the equipment folder is not created directly below the unit folder but is inserted below a
neutral folder, the inserted folder is automatically assumed to be a neutral folder. You can
then set the "Equipment module" object type afterwards in the properties of the hierarchy
folder in the "S88 type definition" tab.
A hierarchy folder that was type defined as equipment module has the following icon in the
plant view in the SIMATIC Manager:
