● 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.

■
Eth 2 with a fixed IP address
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.
7&8
A TCU is a SINUMERIK DHCP client.
The TCU has a single Ethernet connection.
A TCU executes a boot via the network. The boot server is the computer node from which the
TCU also obtains its IP address.
Pre-configuration of the PCU
A PCU has two Ethernet interfaces with default settings suitable for use with SINUMERIK
solution line:
3&8

(WK
Eth 1 is pre-selected as a default DHCP client for connection to a
company network.
Eth 2 is pre-selected as a SINUMERIK DHCP server for connection
to a system network. On Eth 2 the fixed IP address
192.168.214.241 is pre-selected.
Preconfiguration of the NCU
On the X120, the NCU is preconfigured for the SINUMERIK DHCP protocol. The NCU is pre-
selected here as a SINUMERIK DHCP server. On X120, the NCU occupies the fixed IP address
192.168.214.1 with the subnet mask 255.255.255.0 in its capacity as a DHCP server. The
DHCP server of the NCU assigns IP addresses from the range 192.168.214.10 –
192.168.214.239 to the DHCP clients. The behavior of the NCU on X120 cannot be
modified.
