Abstract:
BACnet is a communication protocol for Building
Automation and Control networks that has been developed
by ASHRAE Standards Project Committee (SPC) 135P. The
committee has been working on the standard since the
middle of 1987 and published a draft version for public
review in August, 1991. As a result of the public
review (which generated 507 formal comments), numerous
substantive changes have been made to the proposed
standard. Included are changes in object type
definitions, application layer services, and the network
layer, MS/TP and Point-to-Point protocols. Before
describing these changes and why they were made, a brief
overview of BACnet would be helpful.
