The invention relates to a device and method for analysing and diagnosticating a system which are based on a system model and are for industrial plants controlled by logic programmed or wired control automation. The inventive method comprises a model initialisation stage and a stage for establishing a list of inconsistent variables whose value in the system differs from the value predicted by the model. For each value of the inconsistency list the initial list of variables suspected to generate an inconsistent value is established and afterwards, a short list of suspected variables is obtainable by filtering the initial list.
