IP Gateway KNX/BACnet N143
Behavior at bus voltage failure / recovery
Failure of the auxiliary power (DC 24 V) results in a functional failure of the device.
A bus voltage failure results in a functional failure of the device.
On bus voltage recovery the configured actions are executed and, if applicable, new status values are reported.
The device sends "I am" onto BACnet.
Factory default state
In the factory default state, the device has no gateway function.
IP Address: 192.168.1.135
Physical address: 15.15.255
Physical address IP interface 15.15.255
Ports used:
Service
FTP/Firmware updates
BACnet
HTTP / Webserver
DHCP
KNXnet/IP
Behavior on unloading the application program
When the application program is unloaded with ETS the device does not function.
All BACnet objects are still visible but are set to "out of service".
The property "revision number" in the BACnet Device is incremented by one.
The web server stays in operation.
Resetting the device to factory default settings
To bring the ETS configuration data into the delivery state, a master reset can be performed. To do this, the
following steps are necessary:
Supply the device with 24 V voltage.
Disconnect the KNX bus from the device.
Press and hold the programming button for 5 seconds until the Error LED starts flashing.
If the programming button is still pressed (Error LED flashes), connect the bus to the device.
Release the programming button.
The device is restarted without ETS data and with the physical address 15.15.255.
Note: The IP address is reset to 192.168.1.135.
Possible further security measures are
Operate the device only in a secure network environment.
Set up a separate IP network with its own hardware for BACnet communication.
