Overview of the BACnet/IP network
and the FBIP-21 module

Contents of this chapter

This chapter contains a short description of the BACnet/IP network and the FBIP-21
adapter module.

BACnet

BACnet is a standard data communication protocol that enables interoperability
between different building systems (e.g. fire, security, lighting, HVAC, elevator, etc.)
and devices in building automation and control applications. It enables data sharing
among different types of devices from a broad set of suppliers.
You can download the most recent version of the BACnet Protocol Implementation
Conformance Statement (PICS) (3AXD10001248758 [English]) for the FBIP-21 from

BACnet supported network type with FBIP-21

￭
The drive can be used with the following BACnet/IP network types:
BACnet/IP - This network type is used with the existing Ethernet infrastructure, VLAN
and WAN networks. It uses the UDP/IP for compatibility with existing IP infrastructure.
When it is used with multiple IP subnets, an additional device BACnet Broadcast
Management Devices (BBMDs) is required to manage inter-subnet BACnet broadcast
messages. Each subnet requires one BBMD.

Topology of the BACnet/IP network

￭
The below examples show the allowable topologies for a BACnet/IP network with
FBIP-21 module.
