Flex States
The Flex State feature provides a mechanism where any of 256 selected FlexLogic operand
states or any inputs can be used for efficient monitoring.
The feature allows user-customized access to the FlexLogic operand states in the relay.
The state bits are packed so that 16 states may be read out in a single Modbus register. The
state bits can be configured so that all of the states which are of interest are available in a
minimum number of Modbus registers.
