1. General Description
The KNX TP Media Coupler LC100 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, LC100 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, LC100 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 LC100 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, LC100
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
LC100 has no KNX communication objects.
1.2. LC1000 as Programming Interface
LC100 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
- LC100 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, LC100 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.
- LC100’s ETS database entries are available for ETS4 and later.

2.5. 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.

2.6. LC100 as TP Coupler
When LC100 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 LC100 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), LC100 only routes telegrams whose group addresses are entered in its filter table.
If a telegram is routed by LC100 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.

2.5. LC100 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 LC100 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.

7.2. 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 LC100 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.
