BACnet

BACnet is a protocol developed by ASHRAE for building automation and control networking, specifically designed to meet the communication needs of building automation and control systems for applications such as heating, ventilating, air-conditioning control, lighting control, access control and fire detection systems. HSYCO conforms to a functional subset of the BACnet protocol, as defined in ANSI/ASHRAE Standard 135-2010. HSYCO can only be configured as a BACnet/IP client device. BACnet support is implemented as an I/O Server with a data point representation that you can use in the EVENTS language and Java to read and write BACnet’s objects and properties, and to manage asynchronous notification services.

Note The BACnet Vendor Identification Number that has been issued by ASHRAE to Home Systems Consulting SpA is 590.

Communication

HSYCO supports BACnet/IP, where the BACnet messaging protocol is transported over standard IP networks, over local networks. Routing of BACnet traffic is currently not supported by the HSYCO BACnet/IP I/O Server. You should configure only one I/O Server for each LAN used for BACnet traffic. Support for multiple BACnet/IP local networks is achieved by configuring one I/O Server for each network.
