4 Integration of the CS11 architecture
into the DMS7000
A CS11 system can be integrated into a DMS7000 network via a CK11 gateway. Due
to the dissimilarity of the systems special measures must be taken.
4.1 Basis for integration
The telegram functionality of the CS11 is oriented toward the CS10 fire detection sys-
tem. Existing telegrams are re-used as far as possible.
The generous CS11 System limit as well as its complex information structuring cannot
be transported by means of the DSM7000 telegram structure on a 1:1 basis. For this
reason the following rules apply:
 The two telegram address fields ADF1 and ADF2 are combined (ADF1/2) for repre-
senting the datapoint address of a node. The value in ADF1/2 is derived from the
unique SeqNr of the CC11 data base.
 The SeqNr based datapoint addressing supplies no information on the data type of
the node or its relationship to other nodes. This information is supplied separately for
each CC11 by means of a configuration file.
4.2 Addressing
The CS11 datapoint address is translated into the DMS7000 address based on the fol-
lowing rules:
 Sectors
The Sector field
within the DMS7000 telegram is relevant for the datapoint ad-
dressing. This means that several datapoints of the same node can have the same
ADF1/2 address but that they can be distinguished via the sector field.
Certain nodes cannot be assigned to a specific sector. For example an area con-
tains several nodes of the FIRE, PLANT MONITORING, etc. sectors. In this case
the nodes in the logical tree FIRE are assigned to the FIRE sector, whereas the
nodes in the physical tree are assigned to the BASIC sector.
 Datapoint addressing based on sequence number
A CS11 datapoint is principally addressed by means of a unique sequence number
(SeqNr) of the data base within a CC11 station. In the CK11 gateway the SeqNr is
recalculated by a function in such a way that the resulting ADF1/2 number fits into
the (historically grown) telegram address space between 0100 and 9FBF.
 Assigned datapoint addresses
The number ranges 0000 ... 00FF and A000 ... FFFF are reserved for assigned fixed
ADF1/2 address. Fixed addresses are used in nodes that contain multiple datapoints
(area, station).
 Addressing of the CS11 areas
The maximum 16 areas per CS11 correspond to the section addressing in the
CS10.
The ADF1 field
contains hexadecimal “A” followed by the hexadecimal CSX number
of the area.
Example: A1 = area 1, A8 = area 8, AF = area 15, A0 = area 16.
The ADF2 field
contains a fixed, 2-digit value that corresponds to the function of the
datapoint.
Example: EF for the organization datapoint, CD for the General alarm datapoint, etc.
