Recipes
Components of a A recipe consists of a series of recipe entries. Each entry contains a maxi-
recipe
mum of one input field (i.e., variable). Depending on the configuration, ei-
ther direct or symbolic value input can be used in an input field.
The recipe called Mixture could be set up from the following entries.
In contrast to screens, several entries are displayed on the OP simultaneously
for recipes.
Data records on On the OP, the variables allocated to the input fields are assigned with values
the OP
and stored on the OP.
Together, these values form one data record of the recipe.
Several data records can be set up for one recipe. This permits a fruit juice
plant to operate with different types of drinks, for example, by using a differ-
ent data record for each type of drink.
