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.
Table 5–10: FLEXLOGIC™ GATE CHARACTERISTICS
GATES NUMBER OF INPUTS OUTPUT IS ‘1’ (= ON) IF...
NOT 1 input is ‘0’
OR 2 to 16 any input is ‘1’
AND 2 to 16 all inputs are ‘1’
NOR 2 to 16 all inputs are ‘0’
NAND 2 to 16 any input is ‘0’
XOR 2 only one input is ‘1’

TYPE SYNTAX DESCRIPTION NOTES
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.
