6.1 Introduction
With controllers automating the production of specific products in your
factory, you can specify values of weight, volume, mix time, cook time,
temperature, and other variables by assigning those values to memory
locations in the controller.
The capacity of the recipe system allows a maximum of 500 recipes and a
maximum of 30,000 recipe components (or ingredients), of which 7,500 can
be unique. For example, you can have 500 recipes with 60 components each,
or 100 recipes with 300 components each.
The recipe feature offers more than the ability to store and download
parameters in the process. The recipe feature allows either the operator or
the control node to initiate the download of a recipe. You can use the same
recipe across multiple sets of equipment. You can make modifications to the
production recipe without changing the original recipe definition. In effect,
the production recipe is a working copy of the original recipe (Figure 6-1).
Recipe components define data values used by the program in the controller
for producing a batch, such as how much material to release from a storage
bin into a mixer, how long to mix and cook, and what temperatures to use.
