210 • Fieldbus Communication
BACnet/IP
BACnet Application Layer
This layer represents the application layer and interface with the outside. Here,
communication takes place via BACnet.
BACnet Network Layer
On this relay level, data transport via BACnet, PROFIBUS FMS, World-FIP
and/or EIBnet takes place.
BACnet Virtual Link Layer (BVLL)
This layer includes the backup and bit transmission of data. The data can be
transmitted using protocols and connection possibilities that are established in
the Standard. The following technologies are supported:
• ARCNET (Attached Resources Computer Network) as a networking
• ETHERNET as a transmission technology in local networks; specifies
• BACnet/IP uses the UDP Protocol (User Datagram Protocol) for data
• PTP (Point-To-Point) via RS232 as serial connections; enables point-to-
• MS/TP (Master-Slave/Token-Passing) via RS485 as a serial network for
• LonTalk ANSI/EIA709.1 as a fieldbus from the company Echelon with
