Technical Information and Application Examples
Application Examples
Remote access to several locations
Remote operation and remote visualization
In many cases, several locations need to be managed simultaneously.
There are many such examples:
• Monitoring of cooling temperatures in several supermarkets or
warehouses
• Monitoring of fans for failure
• Monitoring of temperature and humidity in several greenhouses
It is now possible to carry out these monitoring tasks centrally via the
Internet/Intranet from absolutely anywhere. This saves you human re-
sources, time and money. And the Internet/Intranet is available every-
where. Commissioning is further facilitated by the fact that distributed
locations can be configured identically.
Benefits
• Plants and locations can be remotely visualized, controlled and moni-
tored via existing networks
• Simple commissioning thanks to options for identical configuration
of different locations
Follow these steps
• Connect one N 148/22 IP interface per location to the KNX
• Connect the N 148/22 IP interface to the LAN
• Configure the N 148/22 IP interface via the Intranet/Internet
• Define the N 148/22 IP interface
You will need
• One IP interface N 148/22 for each property, for example
• 24-V power supply for IP interface N 148/22, e.g. Power over
Ethernet, unchoked bus voltage
• Visualization software
• 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.
VPN (Virtual Private Network) lets you set up a secure subnetwork via
an open, unsecured network (Internet, wireless network) by protecting
all communication against access or being tapped into by unauthorized
third parties. This is achieved by means of „tunneling“ the data traffic
via a VPN server, which means that any connections must be authenti-
cated and that all data is also encoded.
