stand-alone configuration.

Equations for Object IDs (Instance Numbers)

Standard Addressing – Device Object Instance Number (Default):

In the CLSS BACNET-GW, each node has 15,000 object IDs available to it. For each node,
multiply its node number by 15,000 and add the offset calculated below based on what
type of point it is. These numbers define the 22 bits of the BACnet Object Identifier field.
Examples:
Node 15, L01D025 -> (15 x 15000) + ((1 - 1) x 1000) + (25 - 1) = 225024
Node 201, L02M014 -> (201 x 15000) + ((2 - 1) x 1000) + (14 + 299) = 3016213
Node 114, Annunciator 001 -> (114 x 15000) + (1 + 699) = 1711699
Node 20, ZONE0002 -> (20 x 15000) + (2 + 10000) = 310002
Flexible Addressing – Device Object Instance Number:

This is used by GENT panels. It is a default option for GENT panels.
For each node, use following formula to get base address
+ X + 1 . Here X Initial value is zero and will get incremented for each panel. Add the
offset calculated below based on what type of point it is. These numbers define the 22
bits of the BACnet Object Identifier field.
Note: CLSS Gateway mainboard ID is user configurable. CLSS Gateway mainboard ID + X
+ 1 should be in the range 0 to
mainboards make sure that one CLSS Gateway mainboard range (CLSS Gateway
mainboard ID + X + 1) is not conflicting with other.
Examples:
CLSS Gateway mainboardID 1,Node 15 (First Panel Discovered), L01D025 ,
1+1+ 1+ ((1 - 1) x 1000) + (25 - 1) = 27
CLSS Gateway mainboardID 1, Node 201 ( Second panel discovered), L03M014,
1+2+1+((3 - 1) x 1000) + (14 + 299) = 2317
Below point offset equations related to points or devices under a panel is common for
standard addressing and flexible addressing.
Detectors = ((Loop - 1) x 1000) + (Detector Address - 1)
Modules = ((Loop - 1) x 1000) + (Module Address + 299) + Panel#
SECTOR (Multi State Output)
(((Loop - 1) * 50) + Sector Address + 16000)
Interface Device (Group Object)
Detectors = ((Loop - 1) x 1000) + (Detector Address - 1)
Modules = ((Loop - 1) x 1000) + (Module Address + 299) + Panel#
Example:
L01D200 = ((Loop - 1) x 1000) + (Detector Address - 1) = 0 + 199 = GO199
