5.1 System settings
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 fixed IP address 192.168.215.1 with the subnet mask
255.255.255.224). 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 fixed IP address, e.g. by a modem.
Reserved IP addresses for NCU and PCU
The following defaults apply on delivery:
● Connection to the system network with subnet mask 255.255.255.0:
