A typical programming of the control panel i defined CONTROL-BY-EVENT EQUATION (CBE).
During the programming it is necessary to associate to every point, zone or group a CBE equation.
The CONTROL-BY-EVENT equation allows the configurations of a series of conditions that the control panel
will value when the point, the zone or the group are actived, and it will execute the programmed actuations.
To define those conditions it is necessary to compose the CBE equation using the logical users (OR, AND,
XGRP, NOT, DEL, SDEL and TIM).
The “ACTIVE” condition is valid when:
Lxx = n° Line in alarm
RULES FOR THE CORRECT SYNTAX OF THE EQUATION
 The control equations, to be valid and accepted by the control panel, have to follow precise syntax rules. If
there is a syntax mistake, the CBE equation is refused.
 The logical users (OR, AND, ...) that count for more operands, have to be written following this procedure:
OPERATOR (OPERAND-1 OPERAND-2 ...)
 The NOT logical operator is valid only for one operand, and shall be written before the corresponding
operand.
 If several operators are used, the first character of the equation must be a left-hand bracket, and the last
character must be a right-hand bracket
Example : AND(L01 L02)OR(L03 AND (L04 L05))
That means: if the line L01 and L02 are in alarm
OR
the line L03 is in alarm and both lines L04 and L05 are in alarm
then there will be the activation of the associated output
 Operator available in the control by event equation:
OR
It is the operator which requires AT LEAST ONE operand to be ACTIVE.
Example: the output module equation is: OR (L09 L15 L23) or the OR operator can be omitted by entering:
(L09 L15 L23)
If ANY of the three operands in this equation (L9 L15 L23) is in alarm; the output module will be activated, that
is:
- IF the line L09 is in alarm, or
- IF the line L15 is in alarm, or
- IF the line L23 is in alarm
- THEN this output module will be activated.
