Protocol Problems!
• A man speaking on the phone cannot
communicate with a Fax Machine
• It is not a problem of language now!
• It is the media which has become a
problem
Perhaps you can have some conversion process to
enable communications

Proper Common Protocol
• Protocol is like a language with its set of
rules i.e., grammar, a dictionary, etc.
• Voice or Fax or Email are the ways of
communication (RS 232, RS 485,
Ethernet…)
• Communication Speed is important (Baud)
• You will see conversions of media or
protocol being done to achieve
communication

we need to couple dissimilar LAN
technologies and control the traffic
exchanged between them

BACnet - PICS
•Protocol Implementation Conformance Statement
• BACnet PICS help categorize the capabilities and
functionality of devices
• PICS is a list of features that the device supports
• PICS lists the objects present in the device and
whether the device initiates a service request (asks
or commands) or executes the request (responds or
acts) and how it communicates.
• Earlier model used 6 Conformance Class. Each with
more functionality than the previous level

BACnet – Introducing BIBBs
•BACnet Interoperability Building Blocks
• The new way of specifying BACnet
• BIBBs are there to bring the BACnet to
layman’s level
• BIBBs are used to get over the problems of
working with “Conformance Class”
• The BIBBs fall into five principal areas: data
sharing, alarms and events, scheduling,
trending and device management.

BACnet – More on BIBBs
• In each of these areas there are a number of
kinds of interoperable function one might need
to perform. Each function always has two
entities involved, normally an "asking device"
(Client) and an "answering device“ (Server),
