UNIVERSAL TELEPROTECTION TPU-1
INSTALLATION AND COMMISSIONING MANUAL Web version TPU-1R - Rev. 5.9 (May 2018)
51/69
The devices (hosts) of a single local area network are only able to connect directly with
devices that have the same network number in their IP address. If they have a different
network number they are unable to communicate unless there is another device that allows
a connection to be made between the two networks. The IP address of these devices
capable of connecting different networks is the one that in the hosts is identified as the
default gateway.
In this way, to configure the IP address, the subnet mask and the default gateway of the
web server of the TPU-1 terminal and the management computer, it must be considered
whether or not they belong to the same network.
If the TPU-1 terminal and the computer are connected directly or through a LAN (they
belong to the same network), the IP address of each of them must have the same network
number and a different host number, so the subnet mask must be the same for both. The
default gateway does not need to be configured.
If the TPU-1 terminal and the management computer belong to different LANs and the
connection between them is via WAN, their IP addresses may have a different network
number, but both must be connected to some device (default gateway) capable of
interconnecting LANs.
