11.4 Summary of the bus load calculation

If we should draw a conclusion here again:
The optimum function of the KNX network depends directly on the most accurate
estimation of the data rate in the most unfavourable and average condition. You should
always take into account, that the bus system is first and foremost event-driven and
cyclical repetitions of unchanged states are only necessary as back-up functions with a
relatively long time interval.
Lines or backbone couplers shall be set to “normal” mode, when normal operation is
adopted, i.e. the filter tables must be loaded, and the evaluation algorithm for the filtered
transmission must be activated.

12 Administration functions, project documentation and
archiving

12.1 Reports
In order to document a project, a series of reports are at your disposal.
There are different perspectives to create documentation:
a) Building structure with allocated devices
b) Parts list (important for orders!)
c) Bus topology overview
d) Detailed lines and device lists
e) Group addresses
f) Commissioning status

A detailed printout of the Building View with all available information would already be
sufficient in theory. However, it would be very difficult to quickly find out from this report -
purely arranged according to the building structure - information for instance about the
equipment of a bus line, about the whole topology structure and about the number and
structure of the group addresses used. The information as to which devices was
downloaded and with which result can also not be deduced from that.
The device details, i.e. configuration of flags, object flags, comments and assigned
addresses, should not be printed out in the Building View but in a detailed line printout.

How to proceed?
It shall be first noted that ETS reports always produce a global view of the project. Print
outs of certain parts of the installation are only possible via partial printouts or by exporting
to a file format other than ETS (see below).
