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.

Factory default settings

Meaning of the symbols:
Preconfiguration of the TCU
The TCU is configured as a DHCP client and primarily accepts IP addresses from SINUMERIK
components, from the DHCP server of such components that are inherent to SINUMERIK, for
example, an NCU at X120 or a PCU on the system network or from a default DHCP server.
The behavior of the TCU cannot be modified here.
A TCU executes a boot via the network. The boot server is the computer node from which the
TCU also obtains its IP address.

○ Eth 1 as a DHCP client
● Eth 2 as a DHCP server
