What is a KNX IP router?

The KNX IP Router allows forwarding of telegrams between different lines (TP) through a LAN (IP) as a fast backbone (KNXnet/IP Routing). The KNX IP Router can also be used as an interface for accessing the bus via IP (KNXnet/IP Tunneling). The device supports 5 simultaneous KNXnet/IP Tunneling connections.

What is KNX IP Interface?

The KNX IP Interface serves as a universal interface for PC or Laptop to the KNX bus. The KNX bus can be accessed from any point on the LAN. Power is supplied via the KNX bus. Installation and Connection. The KNX IP Interface is designed for installation on a DIN rail with a width of 1 unit (18mm).

What is KNX backbone?

IP network, used as backbone line The IP network is used as the backbone for KNX. The communication protocol between KNXnet/IP routers is the KNXnet/IP Routing protocol.

What is KNX tunneling?

Tunneling refers to point-to-point exchange of KNX telegrams over an IP network between a KNXnet/IP server and a KNXnet/IP client for configuration and diagnostics. Tunneling is implemented at the KNX data link layer by transferring link layer frames.

What is KNXnet IP?

KNXnet/IP is the protocol used to extend the KNX bus across an IP network. To augment the KNX bus with an IP network, a KNX IP interface is connected to the bus. Tunnelling, used by supervisory systems to communicate with the KNX network. Routing, used for relaying telegrams between two networks.

How does KNX protocol works?

How Does KNX Work? The KNX bus is routed in parallel to the electrical power supply to all devices and systems on the network linking: Sensors (e.g. push buttons, thermostats, anemometers, movement) gather information and send it on the bus as a data telegram.

How does KNX communicate?

A two-core twisted pair data cable (bus cable) is the most common communication medium for KNX installations. Here all devices are connected with one another via the bus cable. Twisted pair cables are cost-effective to buy and easy to install.

What is the difference between KNX and Dali?

KNX offers the same functionality as DALI systems but without the need to individually address each Light fixture meaning a huge cost saving in absence of specialist ballasts per fitting. Instead KNX focuses on the inputs (Switches, Sensors, Thermostats) and controls the corresponding outputs as banks of fittings.

Is KNX wired or wireless?

KNX is the globally recognised standard for wired building technology, which means that it offers the best guarantees in terms of future compatibility and flexibility.

What does a KNX / IP router do for You?

In KNX parlance, what a KNX/IP ‘router’ actually provides is the functionality of a KNX ‘area coupler’ or ‘line coupler’, using a TCP/IP network as the linking medium. An area coupler or a line coupler is a packet forwarding bridge (with built in packet filtering) that moves KNX telegrams (packets) between KNX physical network segments.

What is the KNXnet / IP router IP multicast address?

About the KNXnet/IP router: The IP multicast address of the KNXnet/IP interface is set to 224.0.23.12 and can be changed via ‘Settings’. 224.0.23.12 is a for KNX Association officially registered IP multicast address (at IANA). About the KNXnet/IP interface:

Can A KNX router be a layer 3 router?

It turns out that a KNX/IP ‘router’ is not really a ‘layer 3’ router at all. It is ‘merely’ a layer 2 media bridge. The fact that there is a routing-capable TCP/IP protocol stack inside every IP enabled KNX device doesn’t magically make all those devices into KNX ‘routers’.

Can a router support a second KNXnet connection?

All IP routers will support a second (or multiple) KNXnet/IP Tunnelling connections meaning the device can be used for linking together different KNX lines and also for interfacing to the system. By its very nature, the routing connection has no limits to the number of connections due to the multicast connection.
