Supplementary conditions
For operation of a TCU:
● In the system network, the number of active TCUs is limited:
– a maximum of 2 TCUs: NCU 710.3 PN
– a maximum of 4 TCUs: NCU 720.3 PN or NCU 730.3 PN
– a maximum of 4 TCUs: PCU
Any number of TCUs can be operated in the system network.
● CompactFlash Cards cannot be used on the TCU.
● A 16 bit or 32 bit depth of color setting may be selected.
● If a PC keyboard is connected to the TCU, it is not possible to ensure that all special keys,
e.g., multi-media keys, will be transferred to the software of the NCU / PCU.
● Machine control panels connected via a PROFIBUS network are not supported for
switchover.
● Distributed memory media that are connected to the TCU via USB can be used.
● The TOP Panels must be networked on the basis of the Gigabit standard, e.g. Gigabit switch
or Ethernet cable according to CAT 6 (or higher).

Settings for SINUMERIK solution line
Fundamentals
The system network for SINUMERIK solution line is structured as a star topology with a central
Ethernet switch, to which all Ethernet-based components of the system are connected.
For an NCU the connection is via the X120 Ethernet socket, for a PCU it is via the "Ethernet
2" connection. There is no default for all other components with two Ethernet connections.
These components have an internal 2-port switch and may be used to connect an additional
operator component. Thus, in this case, there can be deviations from the strict star topology.
System network
In the system network, the IP address 192.168.214.xxx with subnet mask 255.255.255.0 is
pre-selected. Here there is precisely one DHCP server with DNS that can run on one NCU or
one PCU. The server ensures assignment of IP addresses to the Ethernet components in the
system network (DHCP clients) from a specified address band.
