Abstract: A system and method monitor and/or diagnose the operation of a production line of an industrial plant which is controlled by an automation system. The system includes a remote data processing server, which is installed outside of the industrial plant. The remote data processing server is configured to receive a digital input signal reflecting at least one control input signal and a digital output signal reflecting a second operational state, to determine at least first and second modeled states corresponding to the at least first and second operational states, respectively, by inputting the digital input and the digital output signals to a digital observer model of the production line and the automation system and by processing the digital observer model, and to forward the first and second modeled states to an output interface from where they can be accessed by modeling and/or diagnosing modules.
