What is BACnet?
•BACnet is a registered trademark of ASHRAE
(American Society of Heating, Refrigeration and Air-Conditioning Engineers)
•BACnet is a standard data transmission protocol
to exchange information among different building
management systems and devices
•BACnet supports numerous network and topology
standards, including the Internet protocol
•BACnet does not require a licence and everyone
can implement it
Today’s topic

9. Network Course
BACnet in Networks
Ethernet:(high rate) transfer bus for data in networks, speeds of 10
Mbit/s or 100 Mbit/s
ARCNET:easily the oldest network standard, rarely found in Europe
but (still) widespread in the USA
Master-Slave/Token-Passing (MS/TP):RS485 series networks,
allowing implementation of simple networks; long lines
(up to approx. 1.2 km), simple cabling (2 or 4 wires)
Point-to-Point (PTP):RS232 series link, allowing a point-to-point
connection between two participants, e.g. telephone connection
(switched network)
Echelon LonTalk:standard used throughout the world for building
management; BACnet uses the transport layer of LonTalk
(e.g. FTT-10 via 2 wires)

22. Network Course
Change-of-value Reporting
To reduce the flow of data on the network, BACnet
has chosen event-dependent communication based
on change of value (COV).
The client registers with (‘subscribes’ to) the server
(SubscribeCOV), which keeps an updated
distribution list (recipient list). When the value
changes (ex Present Value), the client is informed
(notification).
This event (notification) may or may not be acknowledged
(confirmed or unconfirmed).
The lifetime of the subscription may be limited (lifetime)

23. Network Course
Change-of-value Reporting
Events that triggers a notification:
–Present Value
–Status Flag
This event (notification) may or may not be acknowledged
(confirmed or unconfirmed).
The lifetime of the subscription may be limited (lifetime)

24. Network Course
Intrinsic Reporting
This mechanism allows signalling of an event or
an alarm. It is based on the "Notification Class"
object.
This is an event-dependent service.
The method of registering with the server is the same as for a
COV.
Parameters such as priority, confirmation or no confirmation, etc.,
can be defined.

25. Network Course
Intrinsic Reporting
Alarm function in objects
Simple alarm condition function (upper/lower limit, etc.)
The Input, Output, Value, Loop and Trend objects support intrinsic reporting

26. Network Course
Description and Documentation
of Interoperability
•PICS (Protocol Implementation Conformance Statement)
•PICS is a document describing the environment of functions and objects for a
device.
•The official format for the PICS is defined in the AHSRAE standard, of which it
is part.
•When linking two BACnet devices, it is important to compare their PICS. To
ensure interoperability of the two devices, only those functions, objects and
DataLinkLayers supported by both devices must be used.

FrameFrame
Every NIC reads the destination-MAC in the header of the frame.
Is the Destination-MAC equal my own MAC or Broadcast-MAC -> take packet, remove Layer2-
Header and give it to Layer3
Broadcast-MAC = goes to EVERYONE!
Collision: Frames get lost when sent simultaneously to the Ethernet.

Layer 2
HUB and Switch
•A connecting socket is called PORT.
HUB:
•Connects the hosts
•Sends out frames to all ports except the port where the frame came in
•Does not look at the frame
•Has no intelligence
Switch (Layer 2):
•Looks at the source-MAC (sender address) in the frame-header and keeps in mind:
this MAC is attached to port x.
•This information is kept temporarily in a cache which is called MAC-address-tabe.
•Looks at the destination-MAC (target address) in the frame-header and checks the
MAC-address-table if he knows already where to send the frame out.
•Dest-MAC known -> out to the known port only
•Dest-MAC unknown -> out to all ports (like a HUB)

ICMP
ICMP (Internet Control Message Protocol):
Are generated when
•Errors occurs
•When information is necessary
For example:
•Echo Request / Echo Reply (ping)
•Destination unreachable (Router: “I can not reach this destination”)
•Redirect (Router: “I know the direct way”)
•Source Quench (Router: “I’m overloaded”)

48. IT-network and TCP/IP

52
IP
IP (Internet Protocol):
•Unique addresses/names for networks and hosts
•IP-routing must be used between IP-networks (Router, Layer3-Switch, IP-gateway)
•Broadcast is separated by IP-networks (Segmentation, no routing of Layer2-
Broadcast)
•Special functions which use broadcast, can be handled by routes with a relay-
functionality (e.g. DHCP-relay takes DHCP-broadcast and routes it as unicast to a
configured DHCP-Server)

•C-class: 192.168.0.0 –192.168.254.0
•Private Addresses are used within the LAN.
•At the entry point to the Internet “real” addresses are used. Those addresses are
administrated by IANA (Internet Assigned Numbers Authority), in europe RIPE
(Réseaux IP Européens).
•Firewalls, WAN-Router and devices with similar functions connect “real” addresses
with “private” addresses with NAT (Network Adress Translation)
•IP-Addresses in the Layer3-header will be substituted.

Layer 3
Router and Switch
Router:
•Name of the Hardwareconnecting different physical technologies (Layer1 und
Layer2), today usually the connection between LAN –WAN (e.g. Ethernet with
DSL, Ethernet with MPLS, formerly also Ethernet with TokenRing)
„A Switch is also a Router!“
„Is a Switch also a Router?“
Switch (Layer 3):
•Name of the Hardwareconnecting different IP-networks based on the same
physical technology (Ethernet).
•VLAN (Virtual Local Area Network): technology to “simulate” L2-switches of
different IP-networks inside one switch.
Router (Synonym: IP-Gateway):
•Name for Functionalitythat makes the connection between different IP-networks.

60. IT-network and TCP/IP
basics
64
Layer 3
IP-Routing
Router (Synonym: IP-Gateway):
•Name of the functionalitythat makes the connection between different IP-
networks.
•Knows the IP-networks that are directly connected.
•Stores “which network is reachable with which interface” in the ROUTING-TABLE
(Router=port, L3-Switch=VLAN).
•Networks which are not directly connected can be configured to the ROUTING-
TABLE as “static routes” (“you can reach network x with your next router-colleague
y”)
•You can configure a DEFAULT-GATEWAY where all packets for unknown networks
are sent to (“send everything you don’t know where to send to, to your colleague
Y”). On a router there can exist only 1 default-gateway.
•Multicast is not transported between different networks (VLANs), “multicast routing”
can be configured on intelligent switches (special IT-Know-How necessary.
Attention!: 224.0.0.0-224.255.255.255 is NEVER routed)

61. IT-network and TCP/IP
basics
65
Layer 3
IP-Routing
Why IP-routing?
•Transition to a different technology(e.g. WAN).
•Technologicallimit: end-devices get too much traffic, traffic load “collapses”, ARP-
tables of the switches run over, …
•Redundancy methods, load sharing
•Location of faults: better detection of errors, breakdown limited
•Design: overview, responsibilities
•Security
•Unicast: “one” to “one”
•Broadcast: “one” to “all”
•Multicast: “one” to “many”, who are
just a part of “all”

TCP
TCP (Transmission Control Protocol):
•Connection-orientated: TCP modules first create a virtual connection to exchange
status information
•full-duplex connection
•Delivery is guaranteed
•Sent data is acknowledged (ACK), differentiation between connection
establishment and data transfer is possible
•“sliding window” protocol with timing (time-outs) and retransmits
•Price for security: CPU-/network burden

64. IT-network and TCP/IP
basics
68
UDP
UDP (User Datagram Protocol):
•Connection-less datagramm service: delivery of information is not guaranteed
•No end-to-end control between UDP-modules
•Error detection and correction must be implemented in upper layers
•No differentiation between connection establishment and data transfer
•Suitable for environmentswith low error rates (LANs,WANs with QoS)
•Suitable for time-critical applications (IP-telephony, real-time applications)

65. IT-network and TCP/IP

Port
ports:
How does an application (Client) reach a destination application (Server, Daemon,
Process) on another computer?
•The path of communication between application and UDP/TCP is controlled via
ports.
•The ports are numbered, beginning with 0.
The numbers up to 1024 are assigned to fixed ports: these are “well-known” ports, e.g.
SNMP=161, Telnet=23,…
•A client requiring a service from a server (daemon) will send a request to the
server's assigned well-known port.
•Only one server/daemon can exist on one port on one computer.
