FAULT DETECTION IN AN INDUSTRIAL CONTROLLER DURING SAFETY CONTROL
Application 616/CHENP/2005 published 2007-06-22, filed 2005-04-12
The invention deals with improved reliability in safety critical control of real world objects. Examples of real world objects subject to safety control are gas/smoke/fire detection systems, drilling equipment, pipes and pipelines, distillation columns, compressors, conveyor systems, boilers and turbines. A test application includes all relevant high-level language constructs and is repeatedly executed as assembler code in an industrial controller, which CPU is subject to fault detection during on-line safety control.
