Core functions

In plastics machines, an axis must perform a variety of elementary motion tasks, such as multi-stage PTP movements, pressure control, homing, and so on. Usually, these motion commands are independent of each other and the axis performs only one motion command at a time. TwinCAT 3 Plastic Technology Functions implements and encapsulates each of these motion tasks in a separate FB called a Corefunction.

The Corefunctions were defined in a standardized format. The base axis defined in TwinCAT 3 Plastic Technology Functions provides the common Corefunctions. By deriving a specific axis, the user can also replace or supplement the function of a Corefunction without influencing the behavior of other Corefunctions. This makes the TwinCAT 3 Plastic Technology Functions flexible and easy to customize.
