Fault indication via Ethernet (LAN)
Enhanced plant availability due to early fault detection
Whether dealing with a lamp failure in depots or offices, a drop in
pressure in filters, or pump failure - automated plants in distributed
locations are constantly subject to possible faults/malfunctions. The
earlier such faults are detected, the less costly they are to remedy.
If such plants are being controlled with GAMMA instabus and are con-
nected over LAN/IP, these types of fault indications can be forwarded
over the Internet. A fast response means that the functionality of the
plant is quickly restored and costs are kept to a minimum.
Benefits
• Central solution for distributed locations
• Fast forwarding of fault indications
• Fast responses mean less damage
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 over the Intranet/Internet
• Define the N 148/22 IP interface in your visualization program/ETS
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.
