"The new standard contains all corrections, refinements and
improvements that have been adopted since the standard was first published
in 1995," Steve Bushby, chairman of the committee that wrote the standard,
said. "This makes the document more convenient and easier to use."
Features that have been added to BACnet since its original
publication include: increased capabilities to interconnect systems across
wide area networks using Internet protocols, new objects and services to
support fire detection and other life safety applications, capabilities to
backup and restore devices, standard ways to collect trend data, new tools
to make specifying BACnet systems easier, and a mechanism for making
interoperable extensions to the standard visible.
