AM2020/AFP1010 Control-By-Event Size Limitations
TIM
Operator: The TIM operator is used to specify activation on specific days of the week or year.
Equation: TIM(SU MO TU WE TR FR SA HH.MM HH.MM)
Example: If Z221 CBE is: TIM(SA SU 7.30 13.59)
Zone Z221 will be active on Saturdays and Sundays from 7:30AM to 1:59PM.
Equation: TIM(MM-DD-YY HH.MM HH.MM)
Examples: If Z222 CBE is: TIM(7-4-)
Zone Z222 will be active on July 4th for every year.
If Z222 CBE is: TIM(12-25- 9.00 17.00)
Zone Z222 will be active on December 25th for every year from 9:00AM to 5:00PM.
A.4 Size Limitations
Each Control-By-Event has a physical size limitation of 14 bytes in control panel memory.
For initiating devices, the Control-By-Event size can be calculated by the following formula:
Size in bytes = 2 + (Number of Zones) + (Number of Control Modules X 3)
Example: The following Control-By-Event takes up 11 bytes in memory.
(Z1 Z6 Z12 L2M4 L7M15)
Size in bytes 2 + ( 3 ) + ( 2 X 3 ) = 11
For notification devices, the Control-By-Event 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 bytes
