Using the service “ReadProperty” means polling the object with a request, and receive an answer containing the data using COV notification means subscribing to the device for a notification when the “Present_Value” of a Data Object changes. In order to get the value of the property “Present_Value”, it is possible to choose between two ways : sending a request “ReadProperty” or subscribing a COV (Change Of Value) notification for the Data Object. The BACnet protocol has a number of services that permit to read/write the properties of the configured Data Objects. Annex to the document contains specification of the BACnet transported over IP, which is the implementation chosen for this driver. The ANSI/ASHRAE Standard 135-2004 document contains the protocol definition. The BACnet/IP driver provides communication with devices supporting BACnet protocol in its implementation over IP.īACnet is a protocol defined by ASHRAE (American Society of Heating, Refrigeration and Air-conditioning Engineers).

For more information about this bus and the related tools, please refer to Our driver can operate in Ethernet communication, where the link between IP network and EIB devices are one or more EIBNet/IP routers. In order to operate correctly with EIB devices, a good knowledge of the Konnex architecture and of the ETS software is required. The EIBus – Konnex Driver was designed specifically to get in communication with Building Automation Devices, connected through EIB bus, or with the new Konnex System, which is the compatible successor of EIB.ĮIB devices, like lights, dimmer, lamps, curtains, switches, …, have to be configured for their net address with the aid of the ETS software.
