Main_Recipe" Organization Block - Siemens SIMATIC S7-1200 Manual

4 Mode of Operation
4.3 Recipe blocks
For the proper functioning in connection with the SFBs "RecipeImport" and
Note
"RecipeExport", the recipe DB has to consist of a one-dimensional array of a
PLC data type or of a struct and it has to have the "Only store in load memory"
attribute in the block properties.
"UDT_Wall_anchors" PLC data type
The "UDT_Wall_anchors" PLC data type includes the elements of a recipe data
record.

"Main_Recipe" organization block

4.3.2
The system instructions and functions are called from the "Main_Recipe" OB:

READ_DBL (recipe data from the relocated recipe DB in the load memory to
the main memory)

WRIT_DBL (write recipe data from the main memory into the relocated recipe
DB in the load memory)

SFB 1003: RecipeExport (exporting relocated recipe data as csv file on the
web server)

SFB 1004: RecipeImport (importing recipe data from uploaded csv file on the
web server into the exported recipe DB in the load memory)
In addition, the teach function to determine the individual weight of a wall anchor is
also executed in the "Main_Recipe" OB.
For this purpose, the total weight of the counted sample is divided by its number.
The thus calculated arithmetic average is saved in the selected recipe data record
as individual weight.
Note Further information about the system instructions and functions can be found in
the chapter 3.2, as well as in the S7-1200 Programmable controller System
Manual (\3\).
