Recipes
Recipes are combinations of variables for a certain purpose. The purpose of
recipes is to transfer data together to the PLC.
During configuration, the recipe is used to specify the data structure. This
structure is then assigned with data in the OP. Since multiple assignment of
the data structure is possible, we will now speak of data records. Data re-
cords are stored on the OP which saves memory space on the PLC.
Let’s assume that orange nectar, orange drink and orange juice are to be pro-
duced using the same bottling station in a fruit juice plant. The mixing ratios
are different for each drink but the ingredients are the same. The information
required for production can be configured as the recipe ”Mixture”.
