3.2.3 Parameter window IP settings
The parameter window IP settings is used to set how the IP Router Secure communicates via IP.
Type of IP communication
Options: Multicast
Unicast
The type of IP communication defines the type of telegrams that the IP Router Secure sends on the IP
network.
• Multicast:
This is the defined type of communication for KNX IP devices for KNXnet/IP from the KNX
Association. This setting should be retained and changed only if the existing network demands that
telegrams are sent as unicast.
For setting the routing multicast address, see Multicast Address .
• Unicast:
The routing for the device is switched off.
This special communication type does not comply with the KNXnet/IP specification. The ABB i-bus ®
Tool is required for configuration.
The
Unicast type of communication cannot be used when the device is operated in KNX Secure
mode. If
Unicast
is selected when KNX Secure mode is active, the ETS switches to
Multicast
. The
Unicast parameterization in the application will be ignored in this case.
KNX Secure mode must be switched off in the ETS in order to be able to use the
Unicast
type of
communication.
Note
A description of the functions is provided in the i-bus ® Tool online help.
