6.2.3 Network configuration
6.2.3.1 Permissible network topologies
Ethernet connection
A SINUMERIK ONE can only be operated as a network within which the individual
components communicate with one another via Ethernet connections. This network must be
set up.
The individual components are factory-set so that the most frequently occurring standard
configurations can be operated without changing the settings related to the network.
Division into system network and company network
On the SINUMERIK ONE, the components are generally split into a company network on the
one hand and a system network on the other.
The connection to the company network provides access to the network drives, for example.
On the system network, process data communication and image transmission runs from the
components with operator software to the display units of the ITC in question.
This separation is performed via the following specified use of the Ethernet interfaces on the
components:
• An ITC is only connected to the system network.
• An NCU is always connected to the system network via X120.
• Ethernet interface Eth 2 of the IPC is preconfigured for connection to the system network;
while Ethernet interface Eth 1 is used for connection to the company network.
• An NCU is connected to the company network via X130.
Meaning of the connections:
Eth 2 with a static IP address
Crossed Ethernet cable (crossover)
