Functionality
From the BACnet system point of view, after the start up process, Intesis subscribes to configured BACnet points or
reads them continuously from their respective BACnet server devices and updates in its memory the value of the
present_value property received from them.
Every one of the present_values is associated to a KNX group object, associated in turn to one or more KNX Group
Addresses. When change occurs in the KNX object, it will be transmitted to KNX TP-1 with its corresponding Group
Address.
Likewise, when change is received in a write-enabled KNX Group Object, change will be written to present_value
property of corresponding BACnet object associated with it (using WriteProperty BACnet service).
Therefore, INKNXBAC---0000 performs as a single KNX device in the KNX TP-1 network offering communication
objects to access the BACnet objects of the configured external BACnet devices.
In the continuous polling of the BACnet server, if an unresponsive BACnet server device is detected, the
corresponding virtual signal inside Intesis will be activated indicating communication error with the BACnet server
device. These virtual signals indicating communication status in real time with the BACnet devices are also accessible
from KNX as a KNX Group Object, like the rest of the points of the gateway.
