| Abstract: | There are many types of redundancy mode of distributed control systems, which offer many convenience and choices for system design. How to choose the right redundancy mode becomes the key for design. Several methods of the design of redundancy of distributed control systems are introduced, including the redundancy for power supply, controller,I/O modules,communication cables and the integral system. The reliability of the redundancy is also analyzed. |
