10.4.6.2 Parameter interconnections
Overview
Parameter values (setpoint and process value) can be passed between the structure elements
of the recipe hierarchy in both directions while the recipe is executing. When setting the
properties of the recipes (Page 577) and the individual recipe steps, you can enter the relevant
specifications for each input material/output material and process parameter for:
● Source
● Data target
Note
Text length for STRING data type
Since SIMATIC BATCH V6.1, the number of characters that can be edited in "STRING"
data type parameters in recipes has been changed from 16 to 254.
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.
Reference to data source
A source (setpoints) from the next higher level can be assigned for the recipe objects RUP,
ROP, RPH, and SUB.
Example: An input material in the RUP can be the source for an input material in a ROP. The
name of the input material is referenced.
Data source = recipe procedure (RP)
Note
Only parameters of the recipe steps and transitions that reference the level of the recipe
procedure as the data source ("passed up" recipe header parameters) can be used as formula
parameters for batch planning.
Reference to data target
For the RUP, ROP, RPH, and SUB recipe objects, the received process values can be passed
on to the next higher level.
