Recipes

Recipes consist of combinations of tags for a specific application. The purpose

of recipes is to transfer several items of data collectively to the PLC. This

transfer requires synchronization between the touch screen and the PLC.

The data structure is defined with the data record in the configuration. Data is

assigned to the structure on the Touch Panel. This data structure (recipe) can be

used more than once and different data can be assigned to it. We refer to data

records to which data has been assigned as “data records”. Data records are

stored on the Touch Panel. This saves memory space on the PLC.

The same bottling machine of a fruit juice filling system is to be used to

produce orange nectar, an orange drink and orange juice. The mixing ratios are

different for each drink, though the ingredients are always the same. The

production details are configured in this example as the “Mixture” recipe.
