2 Commissioning

2.1 Commissioning requirements

The commissioning of a KNX installation does not necessarily require the complete set-up
of the bus installation with all the bus devices. In larger projects (several building
sections), it does make sense to pre-program e.g. bus couplers in one’s office or in the
workshop. Since it is not an absolute requirement during the commissioning stage for the
complete data set to have been loaded into the bus coupler, it may be useful to already
load only the individual addresses into the bus couplers and the remaining relevant data
when the bus couplers have been installed in the installation. Regardless of whether the
commissioning is carried out in the office, workshop or on the building site, the application
modules of the flush-mounted devices should not yet be mounted, so that programming
button and programming LED remain accessible. In distribution boards, covers should be
removed so that also for these KNX devices, the programming button and LEDs remain
accessible. In the case of built-in devices in suspended ceilings or luminaires, it is
advisable to already assign them with their individual address in the workshop, since such
devices are generally only accessible with a great deal of effort once they have been
installed.
The stipulated checks must have been carried out successfully during and after the
installation.
The commissioning can be carried out via
a serial interface (not with 64 bit operating systems)
a USB interface
or a network connection
of the commissioning PC. The required settings are explained in more detail under “Bus
access” and “Configuring the interface”.
If the serial interface of the PC is a 9-pole plug, the serial cable to the KNX data interface
must link the contacts directly (Pin1 to Pin1, Pin2 to Pin2, …, Pin9 to Pin9). Since ETS3, it
is also possible to commission a KNX installation via USB. In both cases, the
corresponding settings must be carried out (see also “Configuring the interface”).

All functions in ETS can either be called from the menu bar or via the context menus (right
mouse button). A large number of functions can also be started directly via icons in the
TM
toolbar. ETS thus behaves like the majority of programs running under the Windows
operating system. All subsequent screenshots only show examples. The functions do not
necessarily have to be called in exactly the same way as described here. During the first
steps with ETS, it is worthwhile using the right mouse button as frequently as possible as
in many cases it leads directly to the desired dialog.
