More Information
Summary:A distributed fault tolerant system for process control based on an enhancement of the distributed recovery block has been implemented and integrated into a chemical processing system. Fault tolerance provisions in the system cover software faults by use of the distributed recovery block (DRB); hardware faults by means of replication, loose coupling, periodic status messages, and restart capability; and network faults by means of replication and diverse interconnection paths. Maintainability is enhanced through an automated restart capability and logging function resident on a system supervisor node.< >
