4.8 Recipes
Various logically related variables can be organized into units known as recipes.
Unlike mask variables, recipe variables are not transferred to the controller imme-
diately after being entered, but are stored in the terminal as data sets. These data
sets are protected against power failure. The data sets can be loaded to the con-
troller as a unit as and when required.
The maximum number of recipes that can be created at programming time is 250.
For each recipe, up to 250 data sets can be created. The data sets can either be
created at programming time and be stored in the operating terminal’s Flash mem-
ory together with the user description or can be entered online on the operating
terminal and are then stored in the battery-backed RAM. Data sets stored in the
Flash memory must be copied to the RAM first before they can be edited. Data sets
that have been edited remain in the battery-backed RAM.
Example for the usage of recipes:
Settings of a machine for manufacturing various products:
Variable Value Unit
The product clamp requires: Material ST37-3
Feedrate 25.00 mm/s
Setpoint Value Axis 1 43.50 mm
Setpoint Value Axis 2 56.30 mm
Cutting Angle 30 ˚
Cutting Speed 110 mm/s
Variable Value Unit
The product shaft requires: Material X20Cr13
Feedrate 20.00 mm/s
Setpoint Value Axis 1 45.60 mm
Setpoint Value Axis 2 51.20 mm
Cutting Angle 45 ˚
Cutting Speed 76 mm/s
The variables Material, Feedrate, Setpoint Value Axis 1, Setpoint Value Axis 2,
Cutting Angle and Cutting Speed can be organized into the recipe ‘Machine Set-
tings for Products’. The variables Feedrate, Setpoint Value Axis 1 and Setpoint
Value Axis 2 are defined as floating point numbers or fixed point numbers while the
variable Cutting Angle is defined as an integer and the variable Material as a selec-
tion text.
The values for manufacturing the products
Clamp and Shaft must be stored as data
sets. Whenever another product is to be manufactured, the data set of the product
to be manufactured next can be loaded into the controller.
The following check list contains all of the elements that are required and useful for
creating and handling a recipe with data sets:
