Engineering and commissioning
6.1
Fundamentals
6.1.1
System environments
For this chapter, sound knowledge about KNX networks and, depending on the
systems environment, sufficient knowledge about operating ETS4 / ETS5, ACS790
or Desigo ABT are presupposed.
Supported system / network environments and available engineering and
commissioning tools are:

Desigo PL-Link
Desigo ABT, SSA
KNX LTE-mode
Synco ACS790
KNX S-mode
ETS4, ETS5
∂ To connect a PC with USB interface to a KNX network, an interface converter
(e.g. OCI700, contained in OCI700.1) is required.
∂ Other ways to connect to a network are IP interfaces, as made available by the
PXC3.. automation station.
∂ The VAV compact controllers are delivered with the default KNX address
0.2.255
∂ Since the VAV compact controllers do have a separate AC 24 V power supply,
their bus load is only 5 mA.
∂ Desigo PL-Link systems do not support the use of line couplers.
6.1.2
Documentation of engineering and commissioning
It is highly recommended to document all planning data and settings in a way that
is easily accessible after a long interval. Especially if special calculated parameters
or plant-specific adaptations had to be made during engineering and
commissioning, these should be clearly noted. For KNX LTE-mode systems, the
engineering and commissioning protocol C3127 ([15]) is available. For KNX S-
mode systems, this functionality can be covered by ETS.
6.1.3
Address labels
The VAV compact controllers are delivered with a removable address label which
contains the unique KNX ID in alphanumeric and barcode representation.
This label can be removed from the device during installation and attached to e.g.
a building plan. The building plan, containing the device locations and their
addresses (IDs) then facilitates further engineering and commissioning remarkably.
This procedure is essential for the recommended engineering and commissioning
workflows below. If the label gets lost, the ID is printed on the device housing as
well.
