1 General
General
1.1 Product and functional overview
The IP Router IPR/S 2.1 connects the KNX bus with the Ethernet network.
KNX telegrams can be sent to or received from other devices via the network. The device uses the KNXnet/IP protocol from the KNX Association for communication. This is not compatible with the EIBlib/IP protocol as used for example, by the IP Gateway IG/S 1.1.
In older documents and in the ETS 3.0e the KNXnet/IP protocol is also referred to as the EIBnet/IP protocol.
Both protocols and specifications are identical.
The IP Router in addition to the tunnelling function for point-to-point communication, also incorporates the functions of a line coupler (routing).
The IP Router can thus distribute telegrams in the network to other lines or areas, as well as receive telegrams from there.

Device name [max. 30 char.]
Options: ABB IP-Router IPR/S
The device name is used for identification of the device on the LAN.
After a search query, e.g. by the ETS, every KNXnet/IP device reports its name and can be allocated accordingly. For example, the installation location can be identified by the names assigned to the devices, e.g. IPR/S, HALL, SUB7, etc.
The text may be a maximum of 30 characters in length. This name is also displayed when this device is determined in the ETS as the communications interface.
For further information see:
IPR/S as a programming interface
IP address assignment
Options: automatically
fixed
automatically: In the standard setting the IP Router expects the assignment of an IP address by a DHCP server (dynamic host configuration protocol). This server responds to a request by assigning a free IP address to the device. If a DHCP server is not available in the network or it does not respond within 30 seconds, the device starts an auto IP procedure. It assigns itself with an address from the reserved range for auto IP addresses (169.254.xxx.yyy).
fixed: If no DHCP server is installed on the network or if the IP address should remain static, it can be assigned as fixed.

4.1 The IP Router in the network
4.1.1 IP Address of the IPR/S
The IP Router is designed for use in 10/100 BaseT networks compliant to
IEEE802.3. The device features an AutoSensing function and sets the baud rate (10 or 100 MBit) automatically.
The IP address of the device can be received from a DHCP server. For this purpose the automatic assignment setting of the IP address in the ETS is required, see parameter window
IP settings . If no DHCP server is found with
this setting, the device starts an AutoIP procedure and autonomously assigns an IP address from the range 169.254.xxx.yyy.
The IP address which the device receives during start-up (via DHCP or
AutoIP) is retained until the next restart (switch on/off or reprogramming).
If the IP address of the IPR/S is to have a fixed assignment, in the ETS a fixed IP address (as well as a subnet mask and standard gateway) are set,
see parameter window IP settings
.

KNX
4.1.2 KNX telegrams in the network
Planning and application
The IP Router sends telegrams from the KNX to the IP network in accordance with the KNXnet/IP protocol specification. These telegrams are sent in the default setting as multicast telegrams to the multicast IP address
224.0.23.12 port 3671. The Multicast IP address 224.0.23.12 is the defined address for the KNXnet/IP from the KNX Association in conjunction with
IANA for KNX-IP devices. This address should be retained and only changed if the existing network demands that another address be used.
As several IP Routers in a network can communicate with one another, multicast communication must be possible between the devices.
Depending on the type of network and the setting of the network components used, e.g. routers, switches or firewalls, the Multicast IP address 224.0.23.12 may need to be enabled explicitly beforehand.
Please discuss the topic with your network administrator.
If no multicast communication is possible in a network, the IPR/S can also send Unicast telegrams to an IP address. This can be, e.g., the IP address of a PC on which the visualisation software is running. The communication is not compliant to the KNXnet/IP specification and currently only functions
(date 08/2008) between ABB-IPR/S devices.
For further information see: Parameter window
Note
With the design of the KNX system it is important to note that the number of transferred telegrams is also limited when IP Routers are used.
Due to the high baud rates on the IP side (10/100 Mbit/s), telegrams may be lost with high levels of data exchange for system reasons on the TP1 line (9.6 kbit/s).

4.1.3 IPR/S as an area coupler
The IP Router in a KNX system can assume the function of an area coupler.
For this purpose it must receive the physical address of an area coupler
(1.0.0…15.0.0). At the present time in an ETS project (ETS3.0f) up to
15 areas can be defined with area couplers.

4.1.4 IPR/S as a line coupler
Planning and application
The IP Router in a KNX system can assume the function of a line coupler.
For this purpose it must receive the physical address of a line coupler
(1.1.0…15.15.0). At the present time in an ETS project (ETS3.0f) up to 225 lines can be defined.
The following illustration shows the topology with IP Routers as line couplers.
G = KNX device
This topology can be defined as a flat topology, as there are KNX main or area lines. The telegrams of a KNX line are transferred directly to the Ethernet.

4.1.5 Mixed topology
Planning and application
If it is necessary in a KNX system to use the IP Router at one point as an area coupler, e.g. office complex, and at another point as a line coupler, e.g. a remote underground garage; this is possible.
It is only necessary to ensure that the IP Router used as a line coupler uses a line coupler address from a free area, e.g. in the illustration it is 2.1.0.
