System configuration
SINUMERIK ONE combines CNC, HMI, PLC, closed-loop control and communication tasks within
a single NCU (Numerical Control Unit).
Connectable 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. A SIMATIC IPC für SINUMERIK can be used for
increased performance in the operating area.
Up to 2 distributed OPs can be operated on one NCU/PCU. 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 30.3 / SIMATIC IPC for SINUMERIK and Machine
Control Panel / Machine Push Button Panel
• SIMATIC Industrial Thin Client V3 (from firmware V3.1.2.0)
• SIMATIC CE panel
• SINUMERIK handheld units
• Distributed PLC I/O
– SIMATIC
e.g. ET200SP and ET200MP
– SINUMERIK via PROFIBUS DP:
e.g. SINUMERIK I/O module PP 72/48D
– SINUMERIK via PROFINET IO:
SINUMERIK I/O modules PP 72/48D PN and PP 72/48D 2/2A PN
• SINAMICS S120 drive system
