Fault Isolation in Object Oriented Control Systems

  title={Fault Isolation in Object Oriented Control Systems},
  author={Magnus Larsson and Inger Klein and Dan Lawesson and Ulf J Nilsson},
This article addresses the problem of fault propagation between software modules in a large-scale control system with object oriented architecture. There exists a con ict between object-oriented design goals such as encapsulation and modularity, and the possibility to suppress propagating error conditions. The propagation manifests itself as many irrelevant error messages, and hence causes problems for system operators and service personnel when attempting to isolate the real fault. We propose… CONTINUE READING
