Machine comprised of main module and intercommunicating replaceable modules

A machine, functioning as a unit, composed of a main module and at least one replaceable module having an ID,

• said main module comprising (i) an ID recognition unit programmed to receive ID information from each replaceable module, and (ii) an action decision unit comprising a decision algorithm programmed to select an action based on preselected signals, said decision algorithm being adjusted based on the ID information;
• said at least one replaceable module comprising (iii) an ID information unit storing ID information identifying said at least one replaceable module, wherein said ID information includes action threshold values at which predetermined actions are triggered, and said decision algorithm includes action thresholds which are updated by said action threshold values, and (iv) an action actuation unit comprising an action algorithm programmed to actuate said at least one replaceable module based on signals from said action decision unit;
• wherein said main module and said at least one replaceable module are communicated via an interface,
• one of the modules being provided with a detection unit programmed to detect a deviation of the actuated action from the selected action, and at least either of said action algorithm or said decision algorithms being modified in predetermined order based on the deviation,
• wherein when the action threshold values used in the decision algorithm are modified, the modified values are saved in the ID information unit of the replaceable module.
