System overview
2.2 System configuration
Components
For operation, programming, and visualization purposes, the corresponding operating software
is already integrated into the CNC software for the NCU and therefore runs on the high-
performance NCU multi-processor module. The SINUMERIK PCU (e.g. SIMATIC IPC for
SINUMERIK) can be used for increased performance in the operating area.
Up to four distributed OPs can be operated on one NCU/IPC. The operator panel can be installed
as a thin client at a distance of up to 100 m.
The following components can be connected to the NCU:
• SINUMERIK operator panel front with TCU x 0.3/IPC and Machine Control Panel/Machine Push
Button Panel
• SIMATIC Thin Client (from firmware V2.0.1)
• SIMATIC CE panel
• SINUMERIK handheld units
• Distributed PLC I/O
– via PROFIBUS DP:
– via PROFINET IO:
• SINAMICS 120 drive system
• Feed and main spindle motors
– Synchronous motors 1FT / 1FK / 1FE1 / 2SP1
– 1PH / 1PM induction motors
– Linear / torque motors 1FN / 1FW6
PROFIBUS
PROFIBUS I/O for the PLC/ NCK I/O (isochronous)
NCK / PLC isochronous drives (e.g. ADI 4, CU320)
PROFIsafe V2 at both interfaces
Second DP/MPI isochronous interface available for
NCK
PROFINET
PROFINET I/O for PLC peripherals
PROFINET I/O for NCK peripherals (isochronous)
PLC isochronous drives
NCK isochronous drives (also with Safety Integra‐
ted)
