Abstract
A method and an apparatus are provided for verifying a fault detection result in a system. The apparatus includes an interface and a control unit. The interface is adapted to receive data associated with a process operation and adapted to receive information provided by a process controller associated with the process operation. The control unit, which is communicatively coupled to the interface, is adapted to perform a fault detection analysis based on the data associated with the process operation and verify a result of the fault detection analysis based on the information provided by the process controller.
