Concept of Libraries

TF8560 TC3 Plastic Technology Functions is a solution that allows the plastics processing industry to rapidly implement TwinCAT 3-based motion tasks.

In plastics processing machines, two different drive types, electric and hydraulic, can be used individually or in combination. The underlying Motion Control libraries for these two drive types are different. Therefore, there is the TwinCAT 3 NC PTP (TF5000) for electric axes and the TwinCAT 3 Hydraulic Positioning (TF5810) for hydraulic axes on the TwinCAT 3 platform. If the control program is developed directly on the basis of these two Motion Control libraries, the customer must re-implement all interfaces that call different libraries when the drive technology is changed.

TC3 Plastic Technology Functions provides a unified interface for the common functions of the hydraulic and electric Motion Control libraries. When developing the control program based on TC3 Plastic Technology Functions, only minimal modification is necessary for a different drive technology.

In addition, the elementary motion tasks commonly used in plastics processing, such as cam plates for wall thickness control, multi-segment PTP motion, and pressure control, have been implemented and fully tested in TC3 Plastic Technology Functions, encapsulated as core functions. Customers are freed from building them from scratch and can directly use the provided components to achieve complex functions with little engineering effort.

TC3 Plastic Technology Functions libraries and license

TC3 Plastic Technology Functions can be considered as an interface between the customer application and the TwinCAT 3 platform. TC3 Plastic Technology Functions consists of three libraries, namely Tc3_PlasticFunctions, Tc3_PlasticNc, and Tc3_PlasticHydraulic. Their dependencies are as shown in the figure below. Tc3_PlasticFunctions implements the common functions for both drive types. The functions specific to the electric or hydraulic axes are implemented respectively in Tc3_PlasticNc and Tc3_PlasticHydraulic and will correspondingly call TF5000 TwinCAT 3 NC PTP or TF5810 TwinCAT 3 Hydraulic Positioning.
