10.3 Structure of recipe data records
Introduction
A recipe data record corresponds to a file card in an individual drawer and thus to a single
product variant. If the fruit juice mixing plant is producing juice, nectar, and fruit drinks, you
would then create a recipe data record in the recipe for each product variant. In this case,
the product variants consist of the different mixing ratios for the ingredients.
A recipe data record is a set of values for the tags defined in the recipe. You enter the values
in the input fields. You can enter the values either during configuration or during runtime on
the HMI device or the machine.
To produce a product, you transfer the appropriate recipe data record from the HMI device to
the connected controller. The values in the recipe data record cannot be changed on the
HMI device unless the configuring engineer has provided for this.
