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 (CMX) is to be activated by any one of 14 software zones:
Z4
Z5
Z2
Z7 Z8
Z13
Z10
Z11
Z3
Z6
Z14Z1
Z9
Z12
L1M1
CMX
By using two reverse-activating zones, the equation with 16 bytes is broken into two smaller equations and
the CBE for the control module uses the two reverse-activating zones as its operands.
Z4
Z5
Z2
Z7 Z8
Z13
Z10
Z11
Z3
Z6
Z14Z1
Z9
Z12
Z239
RZON
Z240
RZON
L1M1
CMX
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)
CBE Equation for Z239:
OR(Z1 Z2 Z3 Z4 Z5 Z6 Z7 Z8)
= 10 Bytes
CBE Equation for Z240:
OR(Z9 Z10 Z11 Z12 Z13 Z14)
= 8 Bytes
CBE Equation for L1M1:
OR(Z239 Z240) = 4 Bytes
