Note
The real addressing can be read out via the device view of the SIWAREX
WP231 weighing module in the "I/O addresses" and "Hardware identifier" menu
item in STEP 7 V14 Basic.
3.2 Recipe management
The recipes are saved in the load memory of the controller (internally or on the
memory card) to relieve the main memory.
In the main memory, only a data structure of the recipe elements has to be defined
as a wild card.
A certain recipe data record is copied from the load memory to the wild card in the
main memory via the "READ_DBL" function.
Recipe information of the wild card in the main memory is copied in a certain recipe
data record via the "WRIT_DBL" function.

Upload
Download
As of CPU firmware V4, the recipe data in the load memory can be copied as csv
file onto the integrated web server of the S7-1200 controller via the "RecipeExport"
function.
Via a web browser on your PG you can download this csv file from the web server,
edit it, save it and upload it again onto the web server (after previously deleting the
original file).
The changed recipe data from the csv file on the web server can then be copied
into the load memory of the controller via the "RecipeImport" function.
