A typical programming of the control unit is defined as
CONTROL-BY-EVENT EQUATION
(CBE).
During the programming phase, a CBE equation must be associated with each point, zone or group
The
CONTROL-BY-EVENT
equation allows to program a series of conditions that the control unit will assess
when the Point, the Zone, the Group are
ACTIVE
, and will perform the programmed operations.
To define these conditions, perform the
CBE
equation by using some logical operators (OR, AND, XGRP, NOT,
DEL, SDEL and TIM).
The “
ACTIVE
” condition is valid when:
Input point (input modules or sensors) = in Alarm
Output point (output Module) = ACTIVATED
Group = one of the points of the group is Active
RULES FOR THE CORRECT SYNTAX OF THE EQUATIONS
To be valid and accepted by the control unit, the control equation must follow some precise syntax rules. If
a syntax errors occurs, the CBE equation is refused.
The logical operators (ex. OR, AND, ...) which are valid for several operands, shall be written by 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
(OPERATOR (OPERAND- 1 OPERAND-2 ...) OPERATOR (OPERAND- 1 OPERAND-2 ...))
N.B. : A programmable CBE for output modules, contains the address of the objects which will activate
them, such as: input sensors, input modules or groups. If the module activation must occur for a
combination of various objects, the AND,OR, ect. operators must be used.
A programmable CBE for input sensors and modules, contains the address of the objects to be
activated in case of alarm, which may be output modules or groups. If it is necessary to activate a series
of objects, just re-write them in sequence, without using any operator.
The following format is also used :
Example :
AND(G1G2)OR(G3AND(G4G5))
Which is equivalent to: 1 - IF BOTH group G1 and group G2 are active
2 - OR
3 – Group G3 is ACTIVE and both group G4 and group G5 are active.
N.B.: the equation must be written without inserting spaces between the characters to be entered.
