IntesisBox BACnet/IP Server - KNX

1.2 Functionality

The integration operation is as follow:
From the KNX system point of view, in the startup process of the gateway and also after a
detection of a KNX bus reset, the gateway polls the KNX signals configured to be updated in
this situation and maintain the received values in memory to be served to the BACnet
system when requested. Also listen for any KNX telegram related to the internal points
configured in it and acts accordingly to the configuration of the related point.
From the BACnet system point of view, after the startup process, the gateway listens for
any subscription (COV) request, serves any polling request or performs any writing request
of its internal points received from BACnet system. The values received from BACnet
become available to be read (and when applicable, written) by the KNX system and vice-
versa.
If a signal has been configured as of type "T" Transmit (in the KNX part), any new value for
the signal coming from the BACnet system is notified to the KNX system with the
corresponding telegram.
When, from the KNX system, a signal is changed (written from any other KNX device for
example), the new value is updated in the gateway's memory and, if this signal is
associated to a BACnet active subscription then the new value will be sent to the
subscripted BACnet device(s).
Also the following functionality is supported by the gateway:
For every point, in the KNX part, one main group address and different listening group
addresses can be defined. With this, from KNX, every point can be addressed not only using
its main group address but also using the other defined listening addresses for the point.
Any change in a gateway's point with the feature "T" activated (in the KNX part), will force
the transmission of this point value with the corresponding telegram to the KNX system.
When the gateway starts up, or after an KNX bus reset, all the points with the feature "U"
or "U2" activated (in the KNX part) will be forced to be read in the KNX system to update its
values in the gateway's internal memory.
Any point with the feature "W" activated (in the KNX part), can be written in any moment
from the KNX system.
Any point with the feature "R" activated (in the KNX part), can be read in any moment from
the KNX system.
All the mentioned features (W,R,T,U) related to the KNX interface are deeply explained in
section 5.1.2.
KNX EIS (data types) supported are: switching (1 bit), dimming (4 bit), float (16 bit),
scaling (8 bit), drive control (1 bit), priority (2 bit), float IEEE (32 bit), counter (8 bit),
counter (16 bit), counter (32 bit), ASCII char (8 bit).
