7 Operating the Application
7.3 Live demo
The "recipe" screen consists of an overview field with information on the selected
recipe data record (1) and an operator panel for the teaching function (2).
In the exported data blocks, a "wall anchor" recipe has been created for this
application with the following three data records:
1. Wall anchor 6mm x 200
2. Wall anchor 8mm x 100
3. Wall anchor 10mm x 50
Select the goods to be packaged via the data record no (3) or the arrow buttons.
As a result, the data information (4) is read from the load memory via the
"READ_DBL" function:

Data record name

Wall anchor diameter

Number of wall anchor

Individual weight of a wall anchor

Weight tolerance for the quality assessment of the quantity filled
Teach function
To determine the individual weight of a wall anchor, proceed as follows:
Table 7-2

1. Place a container on the load cell.
2. Tare the scale.
3. Fill the container with a counted number of
wall anchors.
4. Enter the number of wall anchors in (6).
5. Click the teach button (7).

anchors and indicates the individual weight
of one wall anchor.
The newly determined individual weight is
written in the selected recipe data record in
the exported "RECIPE_DB" data block via
the "WRIT_DBL" function.
7. Then the entire recipe data records are
exported in the relocated "RECIPE_DB" data
block via the "RecipeExport" function in the
"RECIPE_DB.csv" file on the CPU web
server.
