Abstract: In reeling up of a paper web, a continuous paper web is reeled around a reeling core/reeling cores into successive machine reels or customer rolls. The actual control system controlling the reeling up process is supplemented with a substantially separate, model-based learning fault diagnostics. The fault diagnostics in a diagnostic state detects the malfunctions in components critical in view of the operation of the reel-up by monitoring measuring, control and actuating variables of the reel-up and by comparing them with a model formed during a learning state. In a fault tolerance state the fault diagnostics actively affects the measuring, control and actuating variables to maintain the function of the reel-up, and improve operating reliability.
