TwinCAT CNC is a multi-channel CNC control that enables interpolating five-axis machining, among other functions. The path movement is programmed according to DIN 66025. Direct communication to the integrated IEC 61131 PLC enables quick and real-time capable intervention in the CNC, so that complex procedures can be realised.

The TwinCAT I/O system provides a link to all relevant fieldbus systems, including the SERCOS and Profibus DP digital interfaces in synchronous operation (Profibus MC), which are relevant for axis control.

Communication with surface programs (e.g. user interface) is directly via ADS or via the integrated PLC, which is addressed via ADS or OPC. Via the HLI interface, the PLC can access almost the same data as the CNC itself. Additional logic can be integrated.
