KNX Module IC-IP-S.1.0, User Manual

Page: 8 / 23

3 OPERATIONAL DESCRIPTION
In network installations IC-IP-S.1.0 is used as KNX IP interface. A er connecting to KNX TP, IC-IP-S.1.0
operates with its default settings. Setting the correct Individual Address is necessary to include IC-IP-S.1.0
in the present KNX bus system.
3.2 IP NETWORK
IC-IP-S.1.0 sends telegrams from/to the TP network to/from the IP network in accordance with the
KNXnet/IP protocol specification. Important notes:
џ
All KNX IP devices that are intended to communicate with each other via IP must have the same IP
multicast address.
џ
I f the IP address is changed from the IP side it may happen that ETS does no longer recognize the
device and connection cannot be maintained (tunneling uses IP addresses). So, it is recommended
to change IP addresses and restart only from TP side.
џ
I f problems occur for IP address assignment please ask your network administrator.
џ
According to the topology, the Tunneling addresses always have to be assigned in the range of
subline addresses. For more information about additional Individual Addresses for tunneling
please refer to IP Tunneling Address Assignment.
џ
To program devices of a line different to which the device used for (re)programming is connected,
the use of a correct topology is mandatory!
3.1 IP INTERFACE APPLICATION
IP Interface is designed for use in 10/100 BaseT networks compliant to IEEE802.3. The AutoSensing
function sets the baud rate (10 Mbit or 100 Mbit) automatically. IP address can be received from a DHCP
server. For this, the automatic assignment setting of the IP address can be set by ETS (use DHCP). If set so
and no DHCP server is found,
IC-IP-S.1.0 starts an AutoIP procedure and autonomously assigns the IP
address. The IP address that IC-IP-S.1.0 receives during its start-up (via DHCP or AutoIP) is retained until
next start-up (e.g. due to power off or reprogramming). If IC-IP-S.1.0 is supposed to have a fixed IP address
(as well as subnet mask and standard gateway) it can be set by ETS.
ETS does not provide an unload procedure for applications.
