In modern building automation systems a plethora of
different networking technologies exists. Therefore, inter-
operability between devices using various technologies is
a key requirement. The use of Web Services as a platform-
and technological-independent method of communication
is a promising approach to address this challenge. Since
IP extensions to available technologies are more and more
established in building automation systems the network
infrastructure and necessary protocols for Web Services
communication are already present. However, providing
appropriate concepts to model information that can be
accessed in a generic way are still missing. OPC Uni-
fied Architecture (OPC UA) is a powerful and promising
standard that aims at solving this challenge. This work
discusses an approach to map the interworking model
of BACnet to OPC UA. Using the resulting information
model BACnet applications can be represented in OPC
UA and, thus, be accessed by OPC UA clients in a stan-
dard and well-defined way.
