Apparatus and method for functionally securely transfer data in a two-sided data exchange of safety-related data between two communication partners (A, B), wherein a mapping is defined, which assigns to a consumer ID a provider ID of the same end point in the case of each bidirectional connection, and the mapping is made known to the two end points a priori, where the mapping could consist of the one's complement or alternatively of the two's complement, and wherein the connection between the data provider and the data consumer is established as described, the data consumer receives the address identification of the data provider via an additional side channel, for example, and after the connection has been established, the identification of the data provider can be securely checked.

A method for mounting and/or dismantling turbine components is provided. According to this method, a crane is fastened to a turbine casing half in the area of the joint, and at least one component such as for example a turbine blade is brought into its mounted position and/or is removed from its mounted position by means of the crane. For this purpose, the crane has a tower with a multiple section jib having a plurality of segments, thereby allowing the components to be positioned accurately for mounting/dismantling. The mobile crane is connected to the turbine casing half by means of an adapter. The adapter has a fastening pin which is held in place by means of an existing through-bore in the turbine casing half. For the purpose of mounting the mobile crane, the adapter has a baseplate. For rotational locking of the crane, a securing element is provided.

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.

A mounting of an intermediate shaft of a gearbox includes a gear element disposed between a first shaft end and a second shaft end of the intermediate shaft. A first radial bearing is disposed at the first shaft end of the intermediate shaft, a second radial bearing is disposed at the second shaft end of the intermediate shaft, a first axial bearing is disposed at the first shaft end of the intermediate shaft, and a second axial bearing is disposed at the second shaft end of the intermediate shaft.

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.

System and method for identifying data corruption in a data transfer over an error-proof communication link, wherein additional structure checksums are formed to secure a data structure during transfer of the data structure, where representatives are associated with the data types, and the structure checksum is formed via the representatives to provide identification of data corruption in a data transfer over an error-proof communication link between a first automation component and a second automation component in industrial control engineering.

A planetary gear set includes a slide bearing shell arranged on a planet gear axle, a planet gear mounted rotatably on the slide bearing shell and a planet carrier having a recess for receiving the planet gear axle. An axial disk is mounted in a floating manner between a web of the planet carrier and the planet gear in an axial direction and configured flat on an axially outer side facing the web of the planet carrier. A lubricant film between the axial disk and the planet gear ensures during normal operation hydrodynamic operation between the planet gear and the axial disk. A deficient lubrication is present between the axially outer side of the axial disk and the web of the planet carrier.

A planetary transmission includes a planetary stage and a FOFW system having an interrogation unit, a locally fixed antenna electrically connected to the interrogation unit and arranged within a housing of the planetary stage, and a plurality of FOFW sensors fastened to planet gear pins of the planetary stage such that at least two of the FOFW sensors are fastened to each of the planet gear pins. A plurality of co-rotating antennae are fastened to the planet gear carrier at a number corresponding to a number of the planet gear pins. The co-rotating antennae are each electrically connected to at least one of the FOFW sensors and arranged and configured such as to transfer measurement data detected by the FOFW sensors to the locally fixed antenna.

An arrangement includes a shaft arranged within a housing and sized to project through a housing opening, and a shaft sealing ring arranged between the housing and the shaft in a region of the housing opening. A wirelessly interrogatable SAW system has an interrogation unit, at least one stationary first antenna electrically connected to the interrogation unit, at least one rotating second antenna attached in fixed rotative engagement to the shaft, and at least one wirelessly interrogatable SAW sensor attached in fixed rotative engagement to the shaft and electrically connected to the at least one second antenna.
