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.
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.

BACnet Integration
The BACnet driver is implemented as a bidirectional I/O Server. All interaction is based on EVENTS’ IO events and actions. HSYCO conforms to a functional subset of the BACnet protocol.
- The following services are supported:
- Alarm and Event Services:
- ConfirmedCOVNotification
- UnconfirmedCOVNotification
- SubscribeCOV
- Object Access Services:
- ReadProperty
- WriteProperty
- Remote Device Management Services:
- Who-Is
- I-Am
The BACnet I/O Server supports all standard object types and properties for the ReadProperty service, while object’s properties that could be written using the WriteProperty service are listed in the following table. Following HSYCO’s naming convention for BACnet, all object types and properties are written in lowercase letters with no spaces or underscore characters. For example, Present_Value is written as “presentvalue”, and the binary input object type is written as “binaryinput”.
