Cerberus is a Fire, Intrusion, and Gas system. In
a very easy manner, the WinCC OA Cerberus driver ensures the communication
from and to central fire alarm systems and building security components
in case of fire, gas or intruder alarms. The Cerberus system runs on a
C-Bus network. Communication is accomplished through
a DMS7000 (MK7022) which is connected to a CK 11 or CK440 Gateway that
is connected to the C-Bus. On the C-Bus there can
be terminals (CT11, CT4, CT411), Fire Detection centrals (CS10 or CS11),
Intrusion (CS440), or Gas (CS60). The Cerberus
uses sectors for the various functions: W - Fire, L - Extinguishing, S
- Intrusion, G - Gas, P - Plant Monitoring, Z - Basic, K - Data Concentrator
(only CERBAN).
WinCC OA Cerberus Driver is a slave. The
communication is either initialized by the driver at startup, or occurs
automatically after a communication error. All alerts / commands are transmitted
in real time. The transmission status between WinCC OA and the central
fire alarm system is permanently monitored. In the case of a communication
error, the relevant data point element of the driver data point is set
in WinCC OA and can be evaluated for alerts.
The alert- and command range includes the complete range of the telegrams
according to the telegram table V4.4.
