Abstract
The purpose of this paper is to study and develop the redundant control system for the critical process. The critical process means a high priority process which is very essential to the global system. When a fault condition occurs on such process, it affects to other processes. In this paper, the gas pressure process is used a case study. This system consists of dual redundant supervisory control system (HMI Station), dual redundant Ethernet network, triple redundant controller system and triple redundant filed signal. The experimental result is able to indicate some fault tolerance features. Our system can increase the reliability as well as the risk of fault of a whole system and apply to any high priority process appropriately. © 2006 IEEE.
