Some operands can be re-named by the user. These are the names of the breakers in the breaker control feature, the ID
(identification) of contact inputs, the ID of virtual inputs, and the ID of virtual outputs. If the user changes the default name
or ID of any of these operands, the assigned name will appear in the relay list of operands. The default names are shown in
the FlexLogic™ operands table above.
The characteristics of the logic gates are tabulated below, and the operators available in FlexLogic™ are listed in the Flex-
Logic™ operators table.

Editor
INSERT
Insert a parameter in an equation list.
DELETE
Delete a parameter from an equation list.
End
END
The first END encountered signifies the last entry in
the list of processed FlexLogic™ parameters.
One-shot
POSITIVE ONE SHOT One shot that responds to a positive going edge.
A ‘one shot’ refers to a single input gate
that generates a pulse in response to an
edge on the input. The output from a ‘one
shot’ is True (positive) for only one pass
through the FlexLogic™ equation. There is
a maximum of 64 ‘one shots’.
NEGATIVE ONE
SHOT
One shot that responds to a negative going edge.
DUAL ONE SHOT
One shot that responds to both the positive and
negative going edges.
Logic
gate
NOT
Logical NOT
Operates on the previous parameter.
OR(2)
↓
OR(16)
2 input OR gate
↓
16 input OR gate
Operates on the 2 previous parameters.
↓
Operates on the 16 previous parameters.
AND(2)
↓
AND(16)
2 input AND gate
↓
16 input AND gate
Operates on the 2 previous parameters.
↓
Operates on the 16 previous parameters.
NOR(2)
↓
NOR(16)
2 input NOR gate
↓
16 input NOR gate
Operates on the 2 previous parameters.
↓
Operates on the 16 previous parameters.
NAND(2)
↓
NAND(16)
2 input NAND gate
↓
16 input NAND gate
Operates on the 2 previous parameters.
↓
Operates on the 16 previous parameters.
XOR(2)
2 input Exclusive OR gate
Operates on the 2 previous parameters.
LATCH (S,R)
Latch (set, reset): reset-dominant
The parameter preceding LATCH(S,R) is
the reset input. The parameter preceding
the reset input is the set input.
Timer
TIMER 1
↓
TIMER 32
Timer set with FlexLogic™ timer 1 settings.
↓
Timer set with FlexLogic™ timer 32 settings.
The timer is started by the preceding
parameter. The output of the timer is
TIMER #.
Assign
virtual
output
= Virt Op 1
↓
= Virt Op 96
Assigns previous FlexLogic™ operand to virtual
output 1.
↓
Assigns previous FlexLogic™ operand to virtual
output 96.
The virtual output is set by the preceding
parameter
