Configuration 3: IPC with ITC to NCU
In this configuration, a switch is also required for the system network. All components are
connected using suitable Ethernet cables.
The NCU on X120 has the function of the DHCP master with the static IP address
192.168.214.1. For this configuration on Eth 2, the IPC is assigned a static IP address in the
range 192.168.214.241 – 192.168.214.249 with a subnet mask 255.255.255.0. The DHCP
server of the NCU supplies the ITC with an IP address and is used as a boot server for the ITC.
In this configuration, make sure that a SINUMERIK Operate (on the NCU or IPC) is active.
Simultaneous operation of multiple Operates is not permissible.
The observations made for configuration 2 apply here with regard to the connection to the
company network.
To connect one ITC to both HMI systems you must create an additional connection to the
NCU for the ITC.
