Functions of IP Interface Secure
IP Interface Secure is a rail-mounted device for installation in distributions. The device uses
the KNXnet/IP standard and acts as an interface to KNX/EIB via data networks using the
internet protocol (IP). To do so, this device enables bus access from a PC or other data
processing devices.
Connections and power supply
The connection to KNX is established using a bus connector terminal (black and red
terminals). The connection to the data network (IP via 10 or 100BaseT (depending on the
switch)) is established using an RJ–45 socket.
IP Interface Secure also needs operating voltage in order to operate. IP Interface Secure can
obtain this operation voltage via the network line using “Power over Ethernet” as per IEEE
802.3af. Alternatively, the operating voltage can be obtained via the second terminal block
(white-yellow terminals) from an AC/DC 24 V safety extra low voltage supply or from a bus
voltage supply (unchoked voltage, DC 29 V). As soon as the safety extra low voltage supply
is connected to the second terminal block, operating voltage is drawn from it.
Remote access
Even if there is no direct network connection between a PC and an IP interface, you can use
a suitable network infrastructure for remote access to a KNX installation. Five simultaneous
connections (remote accesses) are possible.
Secure remote access
Additional functions
IP Interface Secure has the following attributes:
●
Easy to connect to higher-level systems by using the internet protocol (IP)
●
Direct access to the KNX installation from every point in the IP network (KNXnet/IP
tunneling)
●
Up to five KNXnet/IP tunneling connections are possible at the same time
●
LED displays for operational readiness, KNX communication and IP communication
●
Easy and secure configuration using ETS
●
Easy to connect to visualization systems and facility management systems
●
Slot for SD card (not in use)
