Home and Building HBES Open Communication System is dedicated to the control and monitoring of networked building automation systems (BASs). Currently, Home and Building HBES Open Communication System has limited capability to communicate with other systems, as a result of the use of different protocols, incompatibility or various other restrictions. For the integration of Home and Building HBES Open Communication System and for solving specific problem scenarios, customized solutions are currently on offer. A standard interface between the HBES world and the remaining systems would however constitute a common link to bridge the gap and integrate Home and Building HBES Open Communication System into systems like the traditional Internet or the emerging Internet of Things (loT).
A standard bridge between Home and Building HBES Open Communication System and IT systems based on Web services (WSs) is currently missing to support upcoming use case scenarios. This standard specifies such a standard interface.
The HBES Gateway is an abstract concept, and thus not restricted to any hardware requirements or limitations. Constrained devices can be used as well as enterprise systems as HBES Gateway device. It shall be kept in mind that some configurations may overload the used hardware regarding the mentioned
limitations. For example, a computationally intensive message exchange protocol cannot be used in resource-constrained HBES Gateways. However, the HBES Web services specification defines the HBES Gateway in an abstract and platform-independent way irrespective of any particular hardware.
Figure 1 sketches the intended setting containing the Home and Building HBES Open Communication System, the IT systems and the HBES Gateway between these two components.In a first version, the HBES Gateway and its WS interface is based on OASIS Open Building Information Exchange (OBIX). The OBIX integration is specified in Clauses 8 and 9. The HBES Gateway shall allow browsing of information on the Home and Building HBES Open
Communication System and reading or modifying runtime data of devices, Data points, Functional Blocks, Interface Objects or channels. Thus, any high level management use case to manipulate or monitor the underlying Home and Building HBES Open Communication System is covered by this standard and can be implemented using the presented interfaces.DIN EN 50090-6-1 pdf download.
