The method and the data processing system of the invention monitor the operating states of a technical plant. The operating states of the technical plant are characterized with measured values measured or modeled at a lowest level of the system. The plant is monitored with the measured values and with technological knowledge relevant to the operation of the technical plant stored in a memory of the data processing system. First, the measured values are processed and converted into plant symptoms specific of the associated operating states. Next, a diagnosis of the operational state of the plant is established from the plant symptoms and a significance value is assigned to the diagnosis, or a significance value is first assigned to the plant symptom and the diagnosis is prepared therefrom. The assignment of the significance is based on the technological knowledge. The diagnostic information is thus rated before it is appropriately forwarded to the user surface.
