Technological significance of the Batch hierarchy folders
The three Batch hierarchy folders have the following defined technological meanings according
to the ISA-88 standard:
Batch
hierarchy folder
Level Meaning
Process cell Level 2 Within a project, only one process cell can currently be created. A
recipe can therefore only access phases of this process cell. Exam‐
ples of the process cell level might be polymerization plant, dye‐
house, colored pigment plant, or multipurpose plant.
Unit Level 3 Several units can be defined in one process cell. These units can
be used within a recipe. Examples of units might be neutralization,
extraction, distillation, or preparation.
Equipment module Level 4 Several equipment modules such as a dosing or bottling machine
can be defined in a unit. Equipment phases such as heating, cooling,
ventilating, emptying can be created for the equipment modules.
Included in the naming scheme (yes/no)
The name of the project exists once and is not included in the naming scheme for tags in
WinCC. All other folders can be included in the naming scheme during configuration.
Note
By default, inclusion in the naming scheme is deactivated. This means that no hierarchy folder
is included in the name.
Storage of the blocks
The charts with the corresponding SFC type instances (Page 155) or BATCH interface
blocks (Page 151) can be stored in the appropriate Batch hierarchy folders according to their
technological significance. Only TAG_COLL can be stored in the process cell folder. The
UNIT_PLCs along with EOPs, EPHs and TAG_COLL can be stored in folders of the "Unit"
object type. EPH blocks and TAG_COLL blocks can be stored in folders of the "Equipment
module" object type. The IEPAR blocks should also be saved in the Batch hierarchy folder.
The charts with the function blocks (valves, controllers etc.) and sequential controls (SFC)
required for the automation task can also be stored in these BATCH hierarchy folders. You
can also extend the structure specified by SIMATIC BATCH for the general function blocks
using neutral hierarchy folders so that you produce the ideal plant structure for your
requirements.
