INVARIANT APPROACH APPLICATION IN A DISTRIBUTED CONTROL SYSTEM SELF-DIAGNOSTICS
The application of an invariant approach to information channels self-diagnostics of automated process control system on the example of monitoring a distributed control system is described. The structure of a built-in distributed functional monitoring and diagnostics system with analytical redundancy is given. A majority-dynamic method of a distributed control system reconfiguration is proposed, which provides real-time monitoring, standardless diagnostics and the failed module localization in three stages of reconfiguration.
