Abstract: A machine comprising a first member (12), a second member (40) movable relative to the first member (12), a servo motor (36) for driving the second member (40), a logic controller (38) for controlling the servo motor (36), one or more inputs to the logic controller, the or each input being for transporting operational data, a storage device for storing the operational data, and an interface (50) to the storage device, the interface (50) being for providing access to the operational data. The system is for a form-fill-seal packaging machine comprising the logic controller (38).
