Second, create a recipe data block
● Create your recipe DB as a global data block with the DB property "Only store in load
memory" enabled.
● The name of a recipe data block is used as file name of the corresponding CSV file. The
DB name characters you assign must follow the Windows file system naming restrictions.
Characters \ / : * ? " < > | and the space character are not allowed.
● The recipe array assignment is "Products" as Array [1.. 5] of "Beer_Recipe". The array
size 5 is the maximum number of recipe flavors that are possible.
● The values for recipe components are added as DB start values.
