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/
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.
