KNX line coupler DIN
1. USE
The KNX TP Line Coupler provides a bi-directional data connection
between two KNX TP lines or areas and works as a KNX line/area coupler
in the KNX network. KNX TP main line and KNX TP subline are coupled
having a galvanic isolation in between. Extended frames and long
telegrams with up to 240 bytes APDU length are supported.
Using the TP Coupler application, Line Coupler can be used as KNX
TP line coupler to connect different TP lines, but also as a KNX TP
area coupler to connect different TP areas or installation systems via
a TP Backbone. Telegram filtering is accomplished according to the
installation place in the hierarchy (Physical[ly addressed] Telegrams) and
according to the built in filter tables for group communication (Group
[oriented] Telegrams). For detailed diagnosis, all operational modes/
states are shown by a duo-LED display. Programming on main line from
the subline can be suppressed. Number of repetitions on both KNX TP
lines can be reduced.
Using the TP Repeater application, Line Coupler is able to extend a
KNX TP line providing unfiltered data transfer and galvanic isolation
between segments. Up to four line segments can form a single KNX TP
line by connecting three Line Coupler line repeaters. Each line segment
requires its own KNX power supply unit.
To ease commissioning and troubleshooting, special routing/repetition/
confirmation ETS settings and a configurable Manual Function for short-
time telegram filter switch-off are available. E.g. “transmit all group
telegrams” can be activated by a single button press. After the set time
period, Line Coupler switches back to normal operation automatically.
Another feature to increase the data throughput is the ability to send
IACKs on own telegrams.
1.1 Communication Objects
Line Coupler has no KNX communication objects.
1.2 Line Coupler as Programming Interface
Line Coupler can be used together with the ETS as a programming
interface. The device provides an additional physical address for this
purpose which can be used for a line coupling or repeating.
1.3 Feature Summary
• Line Coupler supports extended frames and long telegrams up to
240 bytes APDU length. (With all MEC couplers and UIM interfaces
long messages e.g. for energy metering applications and visualization
purposes can be processed.)
• IACK sending on sent out messages is ETS configurable.
• When there is no IACK response on the subline, Line Coupler is able
to repeat messages up to three times. Repetitions can be configured
for both Physical Telegrams and Group Telegrams via ETS (to ease
troubleshooting). E.g. after an IACK response no repetition is following
and the negative IACK/BUSY failure mechanism is maintained.
• For an ETS configurable time period, it is possible to switch off
telegram filtering by only pressing a button on the device front
panel. Without additional ETS download filtering is suspended. This is
necessary for running fast diagnostics on site.
• Suspending telegram filtering eases commissioning and debugging.
When filtering is suspended, temporary access to other lines becomes
possible.
• Automatic function for switching back to run-time telegram filtering
after configurable suspension period (see Manual Mode). This avoids
forgetting the reactivation of filtering.
• In networks with high busload the internal amount of communication
buffers are capable of smoothing peeks in the communication load
course.
• Line Coupler’s ETS database entries are available for ETS4 and later.

5.5.2 Button addressing mode
Button for switching between normal operating mode and addressing
mode for assigning the physical address.
5.6 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.

5.OPERATION continued
5.7 Line Coupler as TP Coupler
When Line Coupler receives telegrams (for example during
commissioning) that use Physical Addresses as destination addresses,
it compares the Physical Addresses of the receiver with its own physical
address and decides on that whether it has to route the telegrams or
not.
When Line Coupler 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), Line Coupler only routes telegrams whose group addresses are
entered in its filter table.
If a telegram is routed by Line Coupler 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”. After changing the
configuration setting the filter table entries can be added manually.
Updating the application program version can also be done here.
5.8 Line Coupler as TP Repeater
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 Line Coupler 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”. After changing the
configuration setting the filter table entries can be added manually.
Updating the application program version can also be done here.

7.1.2 Main Line
For Group Telegrams and Physical Telegrams the setting “transmit all”
is intended only for testing purposes. Please do not use for normal
operation.
Note:
If the parameter "Send confirmation on own telegrams" is set to
"yes", the Line Coupler systematically sends an ACK on any own
routed telegram. Since the repeater does not use a filter table, it is
useful to have an ACK sent along with routed telegrams.
