Abstract: The invention relates to a method and a system for collecting, visualising and/or modifying operating data of at least one machine (10) pertaining to the tobacco processing industry. The method involves calling up the operating data by at least one computer (14, 17-20), and a bus system (15, 16) is provided for the system and the device, by which means the operating data can be transferred between at least one control system (13) and at least one computer (14, 17). The inventive method is characterised in that at least some of the operating data is placed on a web server (18) and can be called up via the Internet (21, 31) and/or at least one intranet (16, 32) by at least one other computer (19, 20) which can be connected to the Internet (21, 31) and/or intranet (16, 32). The inventive device is characterised by a data connection (21) enabling at least some of the operating data to be collected, visualised and/or modified via the Internet (21, 31) and/or at least one intranet (16, 32).
