Configuring Control Strategies - Siemens SIMATIC BATCH Operating Manual

7.3.7

Configuring control strategies

Basic procedure
You can configure control strategies for equipment phases or equipment operations in different
ways:
● Configuration of SFC types
When you configure the SFC type, you can also use the characteristics function to specify
the control strategies that are valid for this equipment phase/operation. In addition to this,
the amount of parameters can also be put together based on the setpoints for each control
strategy.
● Configuration of SFCs (SIMATIC Manager and SFC editor)
New control strategies are configured using newly created enumerations with their
properties and the interconnection of the IEPAR_ENUM block with the required IEPH/IEOP
block.
● Configuration in the BATCH configuration dialog
New control strategies are created using new user data types and the assignment of
operation types/phase types as the data type for the control strategy parameter in the
BATCH configuration dialog.
Control strategies and control strategy parameters are included in the process cell data when
you compile and are therefore available later in the BATCH Recipe Editor.
Result: After reading in the type description in the BATCH configuration dialog with the
"Generate" button, the control strategies you edited in this way are indicated by a red flag and
shown under phase types.
Note
Setpoints for the current and prepared control strategy are checked regardless of operating
mode (automatic, manual). When you prepare a control strategy, you must also prepare limits
for the associated setpoints. Otherwise the check will result in an error message.
Procedure for SFC types
Result: in the properties of the SFC type on the "Options" tab, the configured control strategy
is displayed in a check box under Control strategy selection. By enabling or disabling this, you
can decide which control strategies of the SFC type will be passed on to the SFC instances.
Procedure for SFCs
In the SFC, you create the following SFC types for SIMATIC BATCH with the following
characteristics:
● EOP (equipment operation)
● EPH (equipment phase)
The type (EOP or EPH) and the type name are specified for the SFC type. This creates the
interface to SIMATIC BATCH.
