1.5 BACnet services
BACnet services are divided into ve segments:
1) Alarm and event Services
2) File Access Services
3) Object access Services
4) Remote device management Services
5) Virtual terminal Services
For each device prole certain services are mandatory.
1.6 Description of a service: BIBB
BACnet Interoperability Building Blocks (BIBBs) are collections of one or more BACnet
services. These are prescribed in terms of an "A" and a "B" device. Both of these devices are
nodes on a BACnet internetwork. In most cases, the "A" device will act as the user of data (client),
and the "B" device will be the provider of this data (server). In addition, certain BIBBs may also be
predicated on the support of certain, otherwise optional, BACnet objects or properties and may
place constraints on the allowable values of specic properties or service parameters.
