● Data type: For recipe steps to which an EOP, EPH or library reference is assigned, the data
type is taken from the configuration (ES/BatchCC) and cannot be changed. If you create a
new parameter, you have the option of creating a data type yourself. You can choose from
standard data type such as BOOL, REAL, INTEGER, etc. and the user data types from the
global declarations in the ES. You can continue to use the standard data type "Status" in
transitions, to control a ROP independent of the status of another ROP, for example.
Text length for STRING data type
As of SIMATIC BATCH V6.1, the number of characters that can be edited in "STRING"
data type parameters in recipes is 254 instead of 16.
As the configuring engineer, you can increase the number of characters of string setpoints
within an SFC type via parameter assignment (Characteristics > Setpoints). The
"IEPAR_STR"-type block can only process setpoints with a maximum of 16 characters.
However, it is not possible to increase the number of characters here. If, when a batch is
processed, a greater number of characters is written than the block in the AS (SFC-type or
IEPAR_STR) can process, the setpoint is automatically shortened to the maximum possible
length.
● Source: For the RUP, ROP, and RPH recipe objects, a parameter can be selected as the
data source from the next higher level in the selection box. This requires a parameter in
the next higher recipe level with the same data type and of the same unit of measure. If the
selection box does not contain an interconnectable parameter, click "..." to create and
interconnect a new parameter at the appropriate recipe level.
Example:
The recipe phase fetches the setpoint from the ROP level. This can fetch the setpoint from
the recipe unit procedure level, etc. The recipe procedure, in turn, can fetch the setpoint
from the formula.
● Scaling: You can use scaling functions (Page 579) to make processes quantity-dependent.
Depending on the specific quantity of the batch, the parameters in this row are corrected
using the set scaling function. The linear and quadratic scaling functions are available by
default.
● Target: For the RUP, ROP, and RPH recipe objects, the process values from the process
can be passed on to the next higher level.
Example:
The process value of a recipe phase can be passed up to the recipe level of the recipe
header. This also enables the process value of a recipe step to be used as the setpoint for
a subsequent recipe step. The button next to the parameter opens a dialog in which you
can create and interconnect new parameters on all levels.
● Usage (formula): Here, a connector indicates graphically whether or not the variable is the
source for a parameter in the assigned master recipe.
● Setpoint ID, Actual value ID: With an ID number higher than zero, the setpoint or process
value is also made available on an interface for an external program. Assigning unique ID
numbers for the parameter values makes processing in an external application easier.
When a new operation type is created, the default value is 1 or the value set in the ES.
● Display: A maximum of three parameters can be displayed in the step boxes of the SFC
display. Select the parameters you want to be displayed in the step box. All the parameters
are output in the tooltip text.
