Size Limitations AM2020/AFP1010 Control-By-Event
Examples:
1. The following Control-By-Event takes up 13 bytes in memory:
2. The following CBE takes up 11 bytes in memory:
Due to the 14-byte size limitation, it may be necessary to use more than one Equation or List to accomplish a desired result. Through the use
of reverse activating zones, an equation which normally would contain too many bytes can be broken up into several smaller equations.
In the example below, a control module is to be activated by any one of 14 software zones:
CBE Equation for L1M1:
OR( Z1 Z2 Z3 Z4 Z5 Z6 Z7 Z8 Z9 Z10 Z11 Z12 Z13 Z14 )
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 16 Bytes
(too many)
OR( Z1 Z4 Z9 Z16 Z23 L1D3 L2M7 )
Size in bytes 1 + 1 + 1 + 1 + 1 + 1 + 3 + 3 + 1 = 13
DEL( 00.00.30 00.01.30 ( Z1 ) )
Size in bytes1 + 6 +1+1+1+1 = 11
