Abstract: In a packaging machine, a work station has an interior, which is surrounded by a wall and which has arranged therein a tool with at least one heating element or actor. The invention is characterized by a bus node assembly that is attached to the outside of the wall facing away from the interior and which comprises a housing cap, a circuit board and an interface connected to the circuit board and used for connection to a communication bus.

Abstract: A method for operating a packaging machine comprising a work station with an exchangeable tool. A control device may be integrated into the tool. When the tool is in a state of the tool installed into the work station, the control device may regulate a temperature of the tool based on an operating temperature target specification by suitably supplying a heating device integrated into the tool with electrical power. Further, when the tool is in a state removed from the work station, the tool may be connected to an external power supply, and the control device may regulate the temperature of the tool based on a preheating temperature target specification by suitably supplying the heating device with electrical power provided by the external power supply.

Abstract: A packaging machine (1) having at least one registration device is described, in particular a log-in device (13, 16) for checking the personnel-related access authorization. In order that a log-in procedure for gaining access to the packaging machine (1) is associated with the smallest possible expenditure of time and/or effort, at least one of the log-in devices (13, 16) includes a reading unit for wireless and/or contactless reception of transmitted information from wireless and/or contactless readable portable data storage media (12, 18), as well as an alternative input device for the wired input of information. A data storage medium is also disclosed.
