A recipe consists of a series of recipe entries. Each entry contains a maxi-
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.

Input fields (variables)
In contrast to screens, several entries are displayed on the OP simultaneously
for recipes.
On the OP, the variables allocated to the input fields are assigned with values
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.

All data records are stored on the OP. Only the data record which is active at
the moment is stored on the PLC. This saves memory space in the PLC.
