SINUMERIK operating mode
6.2 Networking
ITC V3, ITC V3 PRO
Operating Instructions, 03/2024, A5E42761061-AF

The configuration is set either through the operator interface of the Sinumerik Operate or in
the "basesys.ini" on the device in question.
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 static IP addresses.
The NCU has three Ethernet connections:
•
X120 to connect to the system network with an active DHCP
server (Eth 0)
X130 to connect to the company network as a default DHCP
client (Eth 1)
X127 as a service connection with an active DHCP server (Ibn
0)
On X130, the NCU is set as a default DHCP client for the address reference from a company
network. The IP address received here is specified by the DHCP server from the company
network.
On X127, an NCU is a standard DHCP server in contrast to the SINUMERIK DHCP server. On
X127, the NCU has the static IP address 192.168.215.1 with the subnet mask
255.255.255.224 as Service input. The IP addresses 192.168.215.2 – 192.168.215.23 are
dynamically assigned to the DHCP clients. The range 192.168.215.24 - 192.168.215.30 is
reserved, and can be used by stations on the network with a static IP address, e.g. by a
modem.
Reserved IP address ranges for NCU and IPC
The following defaults apply on delivery:
• Connection to the system network with subnet mask 255.255.255.0:
192.168.214.2 – 9 For additional NCUs with a static IP address on
Not assigned
192.168.214.10 – 239 For additional ITCs, later for additional IPCs,
DHCP clients
Reserved for EKS (Electronic Key System)
Static IP address of the IPC on Eth 2
For further IPCs with a static IP address
For PGs with a static IP address (Service
connection)
• Service connection with subnet mask 255.255.255.224:
For service purposes with PG, PC
Static IP address, e.g. for a modem
