【Abstract】 This article introduces the theory and optimization of redundancy control system based on Control-Logix. and the key problems of the performance are discussed. At the same time, it presented a way to improve the performance of redundancy system via minimizing scan cycle and switchover time, which is useful for users to realize on the similar system.更多还原
