table starts with the download of the coupler. That is why filter tables are not displayed,
but are loaded straight away in the coupler.
8.4.2 Manually created addresses in the filter table:
Nevertheless, there are cases, in which the tables cannot be generated correctly because
of the fact that devices receive or send telegrams, whose parameters cannot be set in
ETS, for instance gateways or visualisation programs. In this case, a solution is needed to
correctly set the filter tables, just for these addresses.
There are two options available:
a) Manual configuration of the filter table
b) Use of a dummy application
To a): In topology, in addition to the devices created in the line, you can also insert the
group addresses which are to be linked manually.
Figure 42: Manual filter table entries
You can do so simply by dragging the group addresses
from the Group Address view into the Topology view. If
you drop them onto a line, the Properties entry “Manual
filter table entries” appears.
Alternatively, you can also use the input field “From” and
“To” below this list.
This procedure is not appropriate for a larger number of
lines, as one personally has to keep track of where
group addresses need to be inserted manually.
b) is for sure the better method:
8.4.3 Using a dummy application
A dummy application is set as a virtual placeholder for the real visualisation. In the
Topology view, it does indeed look like a bus device but is not really installed. It merely
represents a sort of “calculation aid” for ETS for the setting of filter tables. Let us suppose
a visualisation needs to be used in main line 1.0. You then insert a dummy application in
