Configuration 3: PCU/IPC with TCU on NCU

In this configuration, a switch is also required for the system network. All components are
connected using straight Ethernet cables.
On X120, the NCU occupies the fixed IP address 192.168.214.1 in its capacity as a DHCP
server (not used in this configuration). For this configuration on Eth 2, the PCU/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 TCU with an IP address and serves
as a boot server for the TCU.
The observations made for configuration 2 apply here with regard to the connection to the
company network. The connection to a switch on the company network is made via a patch
cable for Ethernet.
To connect one TCU to both HMI systems you must create an additional connection to the NCU
for the TCU.
