    Abstract: A method for functionally secure connection identification during data exchange between two communication subscribers in a communication system, wherein a first subscriber operates as a data provider with a first address identifier and a second subscriber operates as a data requester with a second address identifier, wherein in a request of safety-related data of the first subscriber in a request message, the second subscriber transmits an order number of the data request and its second address identifier and the first subscriber responds with a response message, the second subscriber subsequently checking to determine whether this message contains (i) a second address identifier of the requesting second subscriber, (ii) an order number of the request message of the second subscriber and (iii) the first address identifier of the requested first subscriber, in the event all checking steps are positive, the safety-related data being accepted and otherwise discarded.

    Abstract: A method for functionally secure connection identification for data exchange via a telegram between a source data service and a sink data service, wherein whether the time stamp of an incoming telegram is older than the time stamp of a predecessor telegram is determined, upon receipt of the predecessor telegram a monitoring counter being started and whether the currently incoming telegram has arrived within a monitoring time is additionally determined, where a local time stamp of a local time basis is compared with the associated time stamp of the incoming telegram and whether a comparison difference does not exceed a period of time is determined, a telegram arriving only being accepted as valid if the time stamp of the arriving telegram is greater than the time stamp of the telegram most recently accepted as valid, and data is valid if the checks are positive, otherwise a fail-safe reaction is triggered.

    Abstract: A method for checking a signal transmission of a specified message with a number of d bits from a sender to a receiver by a control unit using a linear block code generated via a coding tool, a channel model, and a specified linear feedback shift register, which is parameterized via a generator polynomial, wherein the residual error probability of different Markov-modulated Bernoulli processes is calculated, where boundary conditions for signal transmission can be specified by using a characterizing Markov-modulated Bernoulli process and also a linear feedback shift register, where integration of the calculation of the residual error probability is performed in a dynamic, intelligent control circuit such that the respective residual error probabilities can be determined for different generator polynomials.

    Abstract: In a method for the start-up operation of a multi-axis system, with the multi-axis system including, as components, segments connected via respective joints and are movable in one or more axes, and a tool, connected to one of the segments and is movable to a specified position, optical markers are arranged in the environment. Position coordinates of the optical markers in a first, global coordinate system are ascertained and stored in the controller. The environment is captured as image data by a camera system. The image data are transmitted to an AR system and visualized in an output apparatus. The optical markers and virtual markers are represented during the visualization of the image data, wherein a respective virtual marker is assigned to an optical marker. A check is performed as to whether an optical marker and the virtual marker overlay one another in the visualized image data.
