2 OPERATIONAL DESCRIPTION
In network installations LC-S.1 can be used as KNX TP area/line coupler or KNX TP line repeater. Aer
connecting the main line, LC-S.1 operates with its default settings. Setting the correct Individual Address
is necessary. Only Individual Addresses x.y.0 are allowed.
Figure 1. TP coupler application program
When LC-S.1 receives telegrams (for example during commissioning) that use Individual Addresses as
destination addresses, it compares the Individual Addresses of the receiver with its own Individual
Address and decides on that whether it has to route the telegrams or not.
When LC-S.1 receives telegrams that use group addresses as destination addresses, it reacts in
accordance with the parameter settings. During normal operation (with Group Telegram routing set to
filter), LC-S.1 only routes telegrams whose group addresses are entered in its filter table.
If a telegram is routed by LC-S.1 without receiving the corresponding acknowledgement, i.e. due to a
missing receiver or to a transmission error, the telegram will be repeated up to three times (depending on
the ETS setting). With the parameters «Repetitions if errors...», this function can be configured separately
for each line and both kinds of telegrams. It is recommended to use the default parameter setting.
If not already configured as «Line Coupler», the ETS application program «TP Coupler» has to be
downloaded to the device. Under the Information tab the configuration setting can be changed by the
drop-down menu «Change Application Program». Aer changing the configuration setting the filter table
entries can be added manually. Updating the application program version can also be done here.

2.2 TP REPEATER APPLICATION
Any received telegram is routed to all lines irrespective of in which line it is processed. Line repeaters
make no use of a filter table. It is therefore not important whether the telegram is generated within a line
or whether it is sent from an upper line to a lower line via a coupler.
If a telegram is routed by LC-S.1 without receiving the corresponding acknowledgement, i.e. due to a
missing receiver or to a transmission error, the telegram will be repeated up to three times (depending on
the ETS setting). With the parameters «Repetitions if errors...», this function can be configured separately
for each line and both kinds of telegrams. It is recommended to use the default parameter setting.
If not already configured as Line/Area/BB Repeater, the ETS application program
«TP repeater» has to be downloaded to the device. Under the Information tab the configuration setting
can be changed by the drop-down menu «Change Application Program». Aer changing the configuration
setting the filter table entries can be added manually. Updating the application program version can also
be done here.

2.3 KNX NETWORK INSTALLATION
For line coupler functionality in a KNX network LC-S.1 has to use the correct Individual Address of a line
coupler (x.y.0, 1≤ x & y ≤15). In ETS up to 225 addresses can be defined (from 1.1.0 to 15.15.0).
For area coupler functionality in a KNX network LC-S.1 has to use the correct Individual Address of an area
coupler (x.0.0, 1≤ x ≤15). In ETS up to 15 areas can be defined.
If LC-S.1 is used in a KNX system for both purposes, it is only necessary to ensure that the LC-S.1 used as a
line coupler has a line coupler address assigned from a free addressing area. Following figure illustrates
the LC-S.1 router topology for KNX lines and KNX areas.
2.3.1 INDIVIDUAL ADDRESS
Figure 3. LC-S.1 network
Example: If an area coupler with address 1.0.0 already exists on the backbone no line coupler with
address 1.x.0, 1≤ x ≤15 can be added here. Even if no line coupler with address 1.1.0 exists on
the subline of the 1.0.0 area coupler. Vice versa, if a line coupler with address 1.1.0 already
exists in the installation no area coupler with address 1.0.0 can be added.

2.3.2 KNX TOPOLOGY
Via a line/area coupler up to 15 lines can be connected to a main line called an area. It is possible to have
up to 64 bus devices on one line. With use of line repeaters a line can theoretically be extended to 255 bus
devices. This means up to four line segments form a single KNX TP line. But it is common practice on
exceeding 64 bus devices to insert a new line instead of extending the originating one.
The free tree structure of the KNX topology prevents problems caused by circling telegrams and heavy
bus load. To maintain this condition, interconnection between lines or line segments is strictly forbidden.
Figure 4. LC-S.1 network topology
Each line segment requires its own KNX power supply unit.
Using repeaters on the backbone and main lines is not allowed.
Interconnections are not allowed.
