9.5.3 Basics of recipe creation
9.5.3.1 Relationship between header parameters, formula category and external formula
Header parameters (internal formula)
If you want to keep your material and production data directly in the master recipe, you can
do this in the recipe header. This is then known as an internal formula. The material and
production data can be set there during the creation of the master recipe and modified during
batch planning and/or also while a batch is executing. These parameters can be passed on
from the recipe header to individual recipe steps or from the recipe steps to the recipe header.
Interaction between header parameters, formula category and external formula
If you want to manage several material and production data lists for a master recipe, you must
do this outside the master recipe in "external" formulas belonging to a formula category.
In this case, a formula category is assigned to a master recipe. The parameters of the master
recipe are then interconnected with those of the formula category, the parameters that can be
manipulated by an operator using a formula during batch planning are marked. In the formula
category, the parameters are listed with the data type and physical unit. Concrete parameter
values, a high and low limit and a references to the procedure (master recipe), are in the
formula.
The parameters of external formulas can also be modified during batch planning and/or while
a batch is executing.
Note
Internal and external formula must not be congruent, this means, all recipe header parameters
must not be interconnected to an external formula. and not all the parameters of an external
formula need to be used in a master recipe.
