Commissioning a KNX system via Ethernet (WLAN)
Commissioning – Easy access via WLAN
In every GAMMA instabus project, the devices are commissioned after
their installation. First, the physical addresses must be assigned. To do
this, select the device in ETS on the notebook and press the program-
ming key on the device. If you have various devices at different places
such as flush-mounted bus coupling units, this can result in intensive
walkways. That’s the reason why two people usually perform the
commissioning.
You can save yourself this considerable extra work by connecting your
notebook wirelessly to the KNX via WLAN. This lets you move about
freely during commissioning ‒ just take your notebook with you to
each room. Any errors such as mixup of devices due to misunderstan-
dings are ruled out.
Benefits
• Wireless GAMMA instabus commissioning via WLAN
• Possible to move freely throughout the building
• Only one person needed for commissioning
Follow these steps
• Connect the IP interface with the KNX, and connect the WLAN router
to the IP interface using the Ethernet cable – and you can go to each
individual room with your notebook and the ETS
• The related safety and security requirementsgoverning the LAN and
WLAN have to be observed
You will need
• An IP interface N 148/22, for example
• 24-V power supply for IP interface N 148/22, e.g. Power over
Ethernet, unchoked bus voltage
• Ethernet
• WLAN router
• WLAN-enabled notebook
• ETS; see knx.org for the latest version
Note:
WLAN stands for Wireless Local Area Network and describes a
„wireless“ local radio network for data transmission.
WLANs are quick and easy to install, cover large areas and operate
cost-effectively.
