1. Within the framework of the configuration, the
packaged goods are selected with the help of
the recipe management.
In the example project a recipe has been
created as PLC data type
"UDT_Wall_anchors".
The recipe consists of 5 elements:

Name of the product

Diameter of the wall anchors to be
packaged

Individual weight of a wall anchor

Quantity (number of the wall anchor to be
packaged)

Tolerance in gram
2. 3 recipe data records are predefined in the
"RECIPE_DB" recipe data block under the
name "Products" as array of
"UDT_Wall_anchors" with respective start
values.

200 wall anchors with a diameter of 6mm

100 wall anchors with a diameter of 8mm

50 wall anchors with a diameter of 10mm
Set the "Only store in load memory" option in
3.
the properties of the "RECIPE_DB" data block
under "Attributes".
4. The recipe for filling can be selected via the
data record no.
In addition, there is the option to weigh a
counted sample of wall anchors via the
"Teach" function. The detected weight is
divided by the pieces specified and thus the
arithmetic average is calculated and written
into the recipe data record as new individual
weight of a wall anchor.
The weight to be filled can be calculated via
the pieces and the individual weight. The
tolerance is decisive for the later quality
assessment of the packaged product.
