With the new KNXnet/IP standard, KNX telegrams
can be transmitted over Ethernet (LAN). This
enables new applications and solutions.
Existing network infrastructures and technologies
are used to transmit KNX data over greater
distances.
Links between buildings and/or building levels
can be clearly and easily implemented using
KNXnet/IP, see chapter "Application examples".
