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.

Table 1: Parameter General
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.
