2.KNXnet/IP
KSR-01IP is a KNX IP router. KNX IP routers are highly similar to TP line couplers.
The only difference is that they use the IP communication medium as main line and
the KNXnet/IP communication protocol. However, KNX end devices can be
integrated directly via IP. This makes the Ethernet a real KNX medium.
As documented in the KNXnet/IP protocol specifications, KNX telegrams can also
be transmitted encapsulated in IP telegrams. Ethernet networks as well as Internet
can be used to route or tunnel KNX telegrams. In this way, IP interfaces and IP
routers are an alternative to USB data interfaces and TP line/area/backbone
couplers. In the latter case, the normal TP backbone is replaced by a fast Ethernet
based line.
2.1 IP Tunnelling
The presence of the Internet Protocol (IP) has led to the definition of the KNXnet/IP
protocol. KNXnet/IP offers the possibility for point-to-point connections for the ETS
(KNXnet/IP Tunnelling) and/or between supervisory system and KNX installation.
The KNXnet/IP device management enables KNXnet/IP device configuring via the
KNX network in order to reduce the time required for complete network
configuration.
2.2 IP Routing
IP Routing is the way of interconnecting KNX lines and areas by IP network(s) via
KNXnet/IP. In IP networks the KNXnet/IP Routing defines the way of KNXnet/IP
router communication.
2.3 IP Bootloader / Boot Mode
The IP bootloader function is used to completely rewrite the flash memory content
and is not just a simple application download. Both communication stack and
application software are downloaded. The download tool is a separate tool
independent from ETS.
The firmware update procedure via IP is executed by a Web front-end and makes
use of special messages to speed up the process. To be protected, their contents
are encrypted.
Note: Entering Boot Mode is equivalent to activating the IP bootloader function.
