Abstract :
An improved function block based redundancy approach is proposed in this paper. The structure, link organization and data synchronization of improved function block are described. Furthermore, the non-redundancy model, the corresponding device-level redundancy model and improved function block based redundancy model are analyzed in quantitatively. For 1-0-2 type system, improved function block based redundancy model can achieved significantly higher reliability than non-redundant system.
