Recipes
Recipes
are combinations of tags for a certain purpose. The purpose of
recipes is to transfer data together to the PLC. This involves synchronization
between the OP and PLC.
When configuring you define not only the recipe but the data structure too.
The structure is assigned data at the OP
. This data structure (recipe) can be
used repeatedly and assigned dif
ferent data. Recipes assigned data are re
-
ferred to as “data records“. Data records are stored in the OP
. This saves
memory space in the PLC.
Orange nectar
, orange drink and orange juice are to be produced using the
same bottling station at a fruit juice plant. The mixing proportions are dif
fer-
ent for each drink, but the ingredients are always identical. The production
details are configured in this example as the recipe called ”Mixture”.
