BACnet/IP Controller
BIBB (BACnet Interoperability Building Block)
A BIBB defines which BACnet features must be implemented in a device
for each task. Compared to the BIBBs from different manufacturers, com-
mon features represent a basis for interoperability between the devices.
BIBBs form the function blocks for the specific interoperability area (IA)
and define the functions within this base.
A BIBB is formed from the IA in which it is contained, the Service that can
be used and the user (client or server).
Example: DS - RP - A (consisting of IA (DS), Service (RP), User (A))
BIBBs are published in the manufacturers PICS. The Device profile is clas-
sified on the basis of the supported BIBBs.
BIG EU (BACnet Interest Group Europe)
The BIG EU is made up of famous members of the building, planning and
production industries as well as different training facilities. It publishes ref-
erence solutions in the BACnet area to support planners who work in this
field. Among other things the NISTIR (National Institute of Standards and
Technology Interagency Report) Guideline is also published
(http://www.big-eu.de).
Bit
Smallest information unit. Its value can either be 1 or 0.
Bit Rate
Number of bits transmitted within a time unit.
BootP
The Bootstrap Protocol sends configuration data to several control-
lers/computers, etc. (without hard drives). This eliminates the need for man-
ual, individual configuration.
BootP is used at WAGO for assigning IP addresses to couplers/controllers.
DHCP reverts back to BootP.
