Abstract

A diagnosis system for a plant, in particular for a power station plant, such as for a turbo-generator of a steam turbine plant, having a number of interacting plant parts, includes a module being associated with the plant parts for on-line acquisition of measured values and for controlling and processing the measured values. A data bus is connected to the module through interfaces for the transmission of plant-relevant measured values. A coupling module is connected to the data bus for requesting and passing on measured values. An administration module is connected to the coupling module for distribution of the measured values. A number of analysis modules are connected to the administration module for content-dependent processing of the measured values and for outputting characteristics derived therefrom. A memory module is connected to the analysis modules for storing the characteristics from at least one of the analysis modules. A number of module-specific operator modules is connected to the memory module for obtaining the characteristics from the memory module.
