Abstract: A system has at least one machine, including at least one device for exchanging data with another device of the at least one machine or of another machine for a joint solution of a task or with a higher-level device. The system further including a certification device configured to identify the at least one machine with a root certificate and configured to grant a sub-certificate to the at least one device of the machine. The certification device is further configured to sign the sub-certificate with the root certificate of the at least one machine in order to identify the at least one device as belonging to the at least one machine, and the sub-certificate is issued biuniquely for the at least one device.

Abstract: A device includes at least one first and one second module configured to cooperate to solve a task and/or are configured to communicate with a higher-level apparatus, a certification module configured to issue a cryptographic signature for each of the at least one first and second module, and an identity generation module configured to form a first code as an identity of the first module from a signature of the first module, to form a second code as an identity of the second module from a signature of the second module, and to form an overall code from the first and the second codes. The certification module is further configured to sign the overall code with a key in order to issue a unique certificate for the device, which biuniquely identifies the device.

Abstract: The disclosure relates to a method for configuring a control device of an automation system, comprising: detecting a local access token via an interface of the control device; and modifying at least one parameter of the control device, which is designed to configure a data connection of the control device in response to the detection of the local access token.

Abstract: A control system in industrial automation technology includes hardware having at least one processor and at least one storage device, in which applications to be executed by the control system are stored. The control system is configured such that at least two and preferably a plurality of mutually isolated execution environments are provided and/or configured. At least two, and preferably a plurality, of independently executable and/or operating functional modules are included, each of which can be executed and/or operate, in particular exclusively, in an isolated execution environment. The functional modules are characteristic of functions of the control system.

Abstract: A printing arrangement and a printing method for two-sided printing on a recording medium are disclosed, in which conditioning by steam and/or liquid droplets takes place after printing on the first side of the recording medium. Because of the conditioning, damage is avoided to the print image of the first side during subsequent printing on the second side, without the recording medium being impaired by the conditioning.

Abstract: A printing arrangement and printing method are disclosed for two-sided printing on a recording medium, in which intermediate fixing by superheated steam takes place after printing on the first side of the recording medium. Owing to the intermediate fixing, damage to the print image of the first side during subsequent printing on the second side is avoided without the recording medium being impaired by the intermediate fixing.

Abstract: In a method or system to operate a digital printer for double-side printing to a recording medium with toner particles applied with a liquid developer, the digital printer prints first and second sides of the recording medium in succession. Electrophoretic mobility of toner particles of a first toner image on the first side is reduced after application of said first toner image and before application of the second toner image on the second side of the recording medium. The electrophoretic mobility is reduced by drying the first toner image along a drying route in an airflow generated by a blower such that carrier fluid is thus removed from the first toner image. After the application of the second toner image on the second side of the recording medium, both the first and second toner images are simultaneously fixed.

Abstract: A pressure transducer that includes at least two sensors having substantially similar or substantially identical error characteristics, wherein each sensor is arranged to be subjected to an applied pressure and the outputs of the sensors are electrically coupled so that errors associated with one sensor are compensated by errors associated with the other sensor. The sensors may be substantially identical silicon sensors formed in close proximity on the same wafer.
