BACnet/IP Controller
Coaxial Cable
This cable contains one, single conductor and radial shielding for transmit-
ting information.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection)
Random bus access procedure (Carrier Sense Multiple Access with Collision
Detection). When a collision is detected, all subscribers back. After waiting
(a random delay time), the subscribers attempt to re-transmit the data.
D
Deterministic ETHERNET
Deterministic ETHERNET denotes that the runtimes can be defined and cal-
culated in an ETHERNET network. This is possible by setting up a Switched
ETHERNET.
Device profiles (BACnet)
Six (6) device profiles are defined, with each one classifying a minimum
number of functions/BIBBs that are supported.
Classification for the devices is specified in Appendix L of the BACnet stan-
dards and can be used to determine interoperability in the specific IAs.
Standardized Device Profile:
B-OWS BACnet Operator Workstation
B-BC
BACnet Building Controller
B-AAC BACnet Advanced Application Controller
B-SA
BACnet Smart Actuator
B-SS
BACnet Smart Sensor
B-GW
BACnet Gateway
BACnet Gateway Device profiles are published in the manufacturer PICS
and make it easier for the customer to compare different BACnet devices
with respect to their functions and interoperability.
