The fault trees are programmed graphically and run with real time data for fault detection. The package allows the drilling down of the faults to root cause. The online data from historian is used to identify possible faults and then the corresponding fault trees are traversed with the dynamic status of the faults to identify the set of events/status of equipment for the fault.
The entire path of fault tree is identified for understanding the root cause. Remedial measures can be also programmed as operator guides.
