BUILDING AUTOMATION

Description of operation

5. Description of operation

In KNX network systems, router 01507 is used to transfer messages from KNX bus to By-me bus and vice-versa. The message exchange rules are totally defined by the

installer using the dedicated folder (Group objects, Parameters, DCA) created in ETS for the specific device. It can be used normally without activating the Security function

and in ETS projects in which the Security function is active. After connection to KNX IP, router 01507 works with its default settings. A valid individual address must be set.

5.1 General Information

When it receives data which use group addresses, router 01507 behaves in accordance with the settings present in the DCA. During normal operation, it only forward

messages whose group addresses are speciﬁed in the routing rules deﬁned in the DCA.

If the messages forwarded by the router do not receive conﬁrmation, for instance because the recipient is missing or due to a transmission error, the messages will be

repeated up to three times.

The router is intended for use in 10/100 BaseT networks conforming to IEEE802.3. The AutoSensing function automatically sets the baud rate (10 Mbit or 100 Mbit).

The IP address can be received by an DHCP server. For this purpose, the setting of the automatic IP address assignment can be set via ETS (“Obtain an IP address

automatically”). If this setting is conﬁgured but no DHCP server is found, router 01507 starts an AutoIP procedure and autonomously assigns itself an IP address; the

device must have a ﬁxed IP address (a standard gateway and subnet address), it can be set via ETS.

5.2 IP network

Router 01507 sends messages to/from the TP network to/from the IP network in compliance with the speciﬁcations of the KNXnet/IP protocol. ia a supervision soft-

ware, in the case of a default setting, the IP data are sent as IP Multicast to the IP address 224.0.23.12 port 3671. The IP Multicast address 224.0.23.12 is the address

for KNXnet/IP established by the KNX Association together with IANA. We recommend you change this address only if the need arises due to the existing network.

N.B.

• All the KNX IP devices that need to communicate with one another via IP must have the same IP multicast address.

• It may be necessary to change the IP multicast address 224.0.23.12 depending on the type of network and on the settings of the network components.

• For the IP routing and identiﬁcation, the IGMP protocol (Internet Group Management Protocol) is used.

• In the event of problems assigning the IP address, please contact your network administrator.
