2.2 How to determine the IP address of the NCU
NCU in the system network (X120)
On the X120, the NCU is pre-selected as required: No settings are necessary.
NCU in the company network (X130)
On the X130, the NCU is set to the address reference via DHCP. If the company network has
a DHCP server no further settings are required.
Example: Determining the IP address
There are several possibilities for determining the address that the NCU obtained in the
company network:
● If the NCU boots in switch position 8, it shows the IP address on the X130 on the 7-segment
display.
● Once the NCU has booted successfully, open a service shell on the TCU and execute the
following command (Page 56) to obtain the desired information:
SC SHOW IP
If the company network has no available DHCP server or if this cannot be used, you are given
the option to set a fixed address for the NCU on the X130 (in accordance with the addresses
already used in the company network).
The following command displays the IP address on the X130:
SC SHOW IP -X130
Note
The IP addresses can also be set directly from the SINUMERIK Operate user interface in the
"Commissioning" → "Network" operating area.
