Introduction
This manual describes the structure and commissioning of the system network with
SINUMERIK solution line control and operator components with Ethernet-based
communication. The fundamentals of the system network are described first, details and
special cases are described in subsequent chapters.
Fundamentals
The system network for SINUMERIK solution line is structured as a star topology with a central
Ethernet switch, to which all Ethernet-based components of the system are connected.
For an NCU the connection is executed via the X120 Ethernet socket, for PCU it is executed
via the "Ethernet 2" connection. There is no default for all other components with two Ethernet
connections. These components have an internal 2-port switch and may be used to connect
an additional operator component. Thus in this case there can be deviation from the strict star
topology.
System network
In the system network the IP address 192.168.214.xxx with subnet mask 255.255.255.0 is pre-
selected. Here there is precisely one DHCP server with DNS that can run on one NCU or one
PCU. The server ensures assignment of IP addresses to the Ethernet components in the
system network (DHCP clients) from a specified address band.
