BACnet clients can either log in via a so-called COV subscription in which case they are automatically informed about KNX events or they can use the ReadProperty-Service in order to query the status of an object if and when required. Up to 250 objects can be configured.

The device is configured exclusively with the ETS.
No special BACnet knowledge is required for the commissioning process. The “translation” of objects configured with the ETS into BACnet objects happens automatically according to the following pattern:
The BACnet object instance number is identical to the object number in the ETS. Objects with a 1bit data type become “binary“ objects, all others are converted into “analogue” objects. The parameter “object mode“ (INPUT, OUTPUT, VALUE) completes the conversion into a BACnet object.
The ComBridge BACnet gateway is also equipped with a web server to display the current configuration and different states on a website. This means that configuration and commissioning can be directly tested and checked.
In addition, the ComBridge BACnet gateway offers a KNXnet/IP interface so that it can be used as an interface for the ETS or other client software.
