FLEXLOGIC CHAPTER 5: SETTINGS

Some operands can be re-named. These are the names of the breakers in the breaker control feature, the ID (identification)
of contact inputs and outputs, 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 appears in the relay list of operands. The default names are shown in the
FlexLogic operands table.
The characteristics of the logic gates are tabulated in the following table, and the operators available in FlexLogic are
listed in the FlexLogic operators table.

PUSHBUTTON 2 to 6, 12, or 16
depending on front panel
Same set of operands as PUSHBUTTON 1
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’

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
