the physical address of 1.1.0, there must be no KNX IP
LineMaster with the address 1.0.0.
The KNX IP LineMaster has a filter table and thus con-
tributes to reducing bus load. The filter table is automati-
cally generated by the ETS.
Because of the speed difference between the Ethernet
(10 Mbit/s) and KNX (9.6 kbit/s), a far greater number of
telegrams can be transmitted on IP. If several consecu-
tive telegrams are transmitted on the same line, they
must be buffered in the LineMaster to avoid telegram
loss. The KNX IP Linemaster 760 has a memory for 150
telegrams (from IP to KNX).
Bus access function (KNXnet/IP Tunneling)
The KNX IP Linemaster 760 can be used as an interface
to KNX. KNX can be accessed from any point in the LAN.
For this purpose, a second physical address must be
assigned as described in the ETS Connection Manager
section.
ETS database
The following parameters can be set on the ETS:
General:
Device name:
The KNX IP LineMaster 760 can be assigned a name of
your choice. The device name should be descriptive (e.g.
Line TF). It is used to search for and recognize a device.
Monitoring bus voltage failure:
If a KNX failure is detected, it is reported on the IP. Re-
turn of the bus voltage is also reported.
Parameters: disable, enable
IP address assignment:
Automatic
(DHCP):
The IP address is automatically assigned
on the DHCP, i.e. additional settings are
not required. To be able to use this func-
tion, there must be a DHCP server in the
LAN (many DSL routers have an inte-
grated DHCP server).
Manual:
In this case, the IP address, the subnet
and the gateway IP address must be en-
tered manually.
IP configuration:
IP Routing Multicast Address:
This address is used for routing telegrams on IP. The
multicast
IP
address
224.0.23.12
was
reserved
(KNXnet/IP) at the IANA (Internet Assigned Numbers
Authority) for this purpose. If a different multicast IP ad-
dress is required, it must lie within the range of 239.0.0.0
to 239.255.255.255.
IP address:
This is the IP address of the KNX IP LineMaster 760.
IP subnet:
Enter the subnet mask here. The device uses the values
entered in this mask to determine whether there is a
communications partner in the local network. If there is no
partner in the local network, the device will not send the
telegrams directly to the partner but to the gateway that
routes the telegram.
IP gateway address:
Enter the IP address of the gateway here.
Note: If the KNX IP LineMaster will only used in the local
LAN, the entry of 0.0.0.0 can remain unchanged.
Example of assigning IP addresses:
A PC is to be used to access the KNX IP LineMaster 760.
IP address of the PC:
192.168.1.30
Subnet of the PC:
255.255.255.0
The KNX IP LineMaster 760 is located in the same local
LAN, i.e. it uses the same subnet. The subnet constrains
the IP addresses that can be assigned. In this example,
the IP address of the IP LineMaster must be
192.168.1.xx, where xx can be a number from 1 to 254
(with the exception of 30, which is already in use). It must
be ensured that no numbers are assigned twice.
IP address of the IP LineMaster:
192.168.1.31
Subnet of the IP LineMaster:
255.255.255.0
