Abstract
In this paper, a method is proposed that generically determines fault models on the basis of the fault free I/O-behavior of sensor-actuator relations. It is shown how the I/O-behavior of standard components can be represented by patterns. These patterns are extended to fault models on the basis of a set of rules. It is possible to detect and locate state faults and time faults with the extended patterns. The patterns are used as observers for the online-diagnosis of a factory automation system.
