摘要：

This paper describes a redundant control system, which consists of dual computer operation station, redundant programmable logic controller (PLC) and redundant Ethernet. A floats hot standby and synchronization have been established between dual redundant PLCs. Via independent and shareable Ethernet paths, each computer operation station communicates to the same control station. Ethernet communication flows are balanced by various sets of Internet Protocol (IP) network and redundant connection of physical network. It guarantees high robustness of system and high continuous rate of continuous billet-bloom casting (CBBC). This approach can be applied to systems where the requests for reliability are very strict and network communication needs to be open. (C) 2003 Elsevier Ltd. All rights reserved.
