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. For increased performance in the operating area,
the SINUMERIK PCU 50.5 can be used.
Up to 4 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 x0.2 / PCU 50.5 and Machine Control Panel/
● SIMATIC Thin Client (from firmware V2.0.1)
● SIMATIC CE panel
● SINUMERIK handheld units
● Distributed PLC I/O
● SINAMICS 120 drive system
● Feed and main spindle motors
