7.7 Functions
Contains parameters for setting up the math block(s), logic equations and timer functions within the
controller.
Logic Equations Up to 8 logic equations can be configured. Each can combine up to 8 operands (digital
signals) with 7 operators. The elements of each equation are calculated sequentially. Operand
1, Operator 1 and Operand 2 are evaluated first. The result is combined with Operator 2 and
Operand 3. This result is then combined with the next operator and operand and so on to the
end of the equation.
Note. If any of the operand sources are invalid (for example, an alarm that is not configured), the
logic equation output state is zero and invalid.
*2 Logic equations are required to perform an exclusive OR of 3 inputs

Key:
OR* Output is 1 if either or both inputs are 1; output is 0 if both
inputs are 0
AND Output is 1 if both inputs are 1; output is 0 if either input is 0
NOR Output is 0 if either or both inputs are 1; output is 1 if both
inputs are 0
NAND Output is 0 if both inputs are 1; output is 1 if either input is 0
EXOR Output is 0 if both inputs are 0 or both inputs are 1; output
is 1 if one input is 1 and the other is 0
END Terminates the equation.
