3.1 SINUMERIK NCU
3.1.1 Structure of SINUMERIK NCU
Subcomponents of the NCU
A SINUMERIK NCU comprises the following integrated subcomponents:
● PLC
● NCK
● CP
● HMI (SINUMERIK Operate)
● SINAMICS Integrated (DRIVE)
These subcomponents are always a fixed component of an NCU and can only be handled in
combination with the NCU. Subcomponents cannot be individually pasted, copied or moved in
the project or across projects (e.g. in libraries).
Note
Copying and pasting the NCU or the DP master system
You can copy and insert NCUs within a project. For this purpose, switch to the network view or
to the topology view of the project view.
The DP master system (PROFIBUS Integrated) cannot be individually copied, pasted or
deleted. It is considered as an integral part of the NCU.
If you copy an NCU, all integrated subcomponents are also copied, e.g. SINAMICS Integrated
or PROFIBUS Integrated.
Additional connectable components
Optionally, the following components can be connected to the NCU:
● NX10.3 and NX15.3 modules
These components are not inserted automatically when inserting an NCU, but must be
integrated manually (Page 28).
