Commissioning a KNX system via Ethernet (LAN)
Faster downloads save time
In every GAMMA instabus project, the devices are commissioned after
their installation. Once the physical addresses have been assigned,
application programs, parameters and addresses are loaded to the
devices. This can take some time in large-scope projects with many
devices.
The LAN connection from Siemens makes it all go much faster, saving
you time and money. Simply connect your notebook to the GAMMA
instabus via an IP interface and start the download. With a LAN con-
nection, the download takes only half as long as it does with USB.
Benefits
• Plan, configure, commission and diagnose with ETS, the KNX
commissioning software
• Simply connect your notebook and start the download
• Downloading takes only half as long, thereby halving commissioning
times and significantly reducing time at the project site
Follow these steps
• Connect the IP interface to the KNX bus line
• Connect the notebook to the IP interface using the Ethernet crossover
cable – and start the download.
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
• Crossover cable
• LAN-enabled notebook
• ETS; see knx.org for the latest version
Note:
LAN stands for Local Area Network. In LANs, data transport is orga-
nized using the IP (Internet Protocol) – the standard network protocol
on the Internet.
