<p>The invention relates to a method of analyzing the state of a device, such as a multi-operation machine, comprising the stages: feeding into the device an input signal in the form of a reference signal (2) which controls the device, and detecting an output signal (3, 5) from at least one component (6, 8) of the device, which output signal (3, 5) is dependent on how the device is controlled by the reference signal (2), creating a model (11, 13, 14) which represents a model output signal which corresponds to the function or a fault of the component (6, 8) forming part of the device, and comparing the model output signal with the output signal (3, 5) from the component (6, 8).</p> |
