Programming—IFC-1010/2020 Programming 91
Each CBE has a physical size limitation of 14 bytes in control panel
memory.
For initiating device lists, the CBE size can be calculated by the following
formula:
Size in bytes = 1 + (Number of Zones) + (Number Control Modules x 3)
Example:
The following CBE takes up 10 bytes in memory.
(Z1 Z6 Z12 L2M4 L7M15)
Size in bytes 1 + (3) + (2 x 3) = 10
For notification and relay control device equations, the CBE size can be
calculated by adding the components involved using the following values:
( = 1 byte
) = 1 byte
OR( = 1 byte
AND( = 1 byte
NOT( = 1 byte
XZONE( = 1 byte
DEL( = 1 byte
TIM( = 1 byte
SDEL( = 1 byte
Zones = 1 byte each
Initiating devices = 3 bytes each
The time specifications for the DEL, TIM, and SDEL operators = 6.
Examples:
1. The following CBE takes up 13 bytes in memory:
OR(Z1 Z4 Z9 Z16 Z23 LID3 L2M7 )
Size in bytes 1 + 1 + 1 + 1 + 1 + 1 + 3 + 3 + 1 = 13
2. The following CBE takes up 11 bytes in memory:
DEL ( 00.00.30 00.01.30 ( Z1 ) )
Size in bytes 1 + 6 + 1 + 1 + 1 + 1 = 11
