The FlexStates feature provides a mechanism where any of 256 selected FlexLogic™
operand states 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 to the user are available in a minimum number of
Modbus registers.
The state bits may be read out in the FlexStates register array beginning at Modbus
address 0900h. Sixteen states are packed into each register, with the lowest-numbered
state in the lowest-order bit. There are sixteen registers in total to accommodate the 256
state bits.
Select the Settings > Communications > Flex States menu item to open the FlexStates
configuration window.
