As mentioned above, the parameters of an equation can contain either INPUTS or GATES.
Inputs and gates are combined into a FlexLogic™ equation. The sequence of entries in the linear array of
parameters follows the general rules listed in the following section.
Table 5–6: FLEXLOGIC™ INPUT TYPES
INPUTS
INPUT IS “1” (= ON) IF...
element* pickup
the pickup setting of the element is exceeded
element* operate
the pickup setting of the element is exceeded for the programmed time delay
logic inputs 1 to 16
the logic input contact is asserted
virtual inputs 1 to 16
the virtual input is asserted
output relays 1 to 8
the output relay operates
(i.e. evaluation of the FlexLogic™ equation results in a ‘1’)
virtual outputs 1 to 5
the virtual output operates
(i.e. evaluation of the FlexLogic™ equation results in a ‘1’)
timers 1 to 10
the timer runs to completion
(i.e. the ‘start’ condition is met for the programmed time delay)
* element refers to any protection or monitoring element programmed under page
S4 ELEMENTS
Table 5–7: FLEXLOGIC™ GATES
GATES
NUMBER OF INPUTS
OUPUT IS “1” (= ON) IF...
NOT
1
input is ‘0’
OR
2 to 19 (for 20 parameter equations)
2 to 9 (for 10 parameter equations)
any input is ‘1’
AND
2 to 19 (for 20 parameter equations)
2 to 9 (for 10 parameter equations)
all inputs are ‘1’
NOR
2 to 19 (for 20 parameter equations)
2 to 9 (for 10 parameter equations)
all inputs are ‘0’
NAND
2 to 19 (for 20 parameter equations)
2 to 9 (for 10 parameter equations)
any input is ‘0’
XOR
2 to 19 (for 20 parameter equations)
2 to 9 (for 10 parameter equations)
odd number of inputs are ‘1’
