2.2 System configuration
SINUMERIK 840D sl combines CNC, HMI, PLC, closed-loop control, and communication
tasks within a single NCU (Numerical Control Unit).
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 operating performance, the
SINUMERIK PCU 50.3 industrial PC can be used.
Up to four 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.
