5.6 FlexLogic

5.6.1 FlexLogic operands

For flexibility, the arrangement of internal digital logic combines fixed and user-programmed parameters. Logic upon
which individual features are designed is fixed, and all other logic, from contact input signals through elements or
combinations of elements to contact outputs, is variable. The user has complete control of all variable logic through
FlexLogic. In general, the system receives analog and digital inputs that it uses to produce analog and digital outputs. The
figure shows major subsystems of a generic UR-series relay involved in this process.
