5.1.4 Factory default settings
Meaning of the symbols:
○ Eth 1 as a DHCP client
● Eth 2 as a DHCP server
■ 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 (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.
Restricting the available address band that is managed by the DHCP server of the NCU frees
up IP addresses 192.168.214.2 to 192.168.214.9 as well as addresses 192.168.214.241 to
192.168.214.254 for network nodes with fixed IP addresses.
