Abstract: A method and a read/write device for addressing at least one wirelessly accessible data memory in an arrangement having a read/write device for the at least one data memory and an industrial automation component, wherein the data memory is addressed, during radio-based data interchange between the data memory and the read/write device, using a first identification number of the data memory. The read/write device assigns a second identification number to the first identification number of the data memory, and the second identification number is used to identify the data memory in the event of data interchange between the read/write device and the automation component based on this data memory. As a result, the automation component can use shortened identification numbers, and there is still unique addressing between the automation component and the wirelessly accessible data memory.

The system comprises first means for creating a file containing the specifications and at least one project planning environment for creating a solution on the basis of the specifications, with the file containing the specifications being imported into the at least one project planning environment as meta knowledge. A simple provision of specifications to be used for a project is hereby enabled.

Abstract: A method for implementing and operating, and a read/write unit for use in, a system that includes multiple contactlessly readable transponders each in having a unique identification number. The read/write unit is connected to an industrial control device of the system and, in a recognition phase, a first of the transponders is detected by the read/write unit. At the start of a holding phase, the identification number of the detected first transponder is stored in a holding register of the read/write unit. Then, during the holding phase, other detected transponders are ignored by the read/write unit. The identification number of the first of the detected transponders is thereafter deleted from the holding register to terminate the holding phase so that it is possible to communicate reliably with a unique transponder even over a relatively long time period without process disturbances arising from the presence of other transponders in the area of the read/write unit.

Abstract: A method of initializing and personalizing a chip card (100) and to a chip card (100) for this purpose. In accordance with the present invention, there are created in the data memory (102) of the chip card (100) data structures (200, 210, 300) which enable the personalizing data which is to be transmitted to the chip card (100) at the time of personalization to be unambiguously assigned to the various chip card applications and thus to the providers of these applications. As a result, the chip card applications are securely isolated from one another at the time of personalization.

Abstract: A chip card has a program execution unit and a memory for at least one program that can be reloaded as a function of the application. In every reloadable program, first command instructions having absolute address parameters that refer to memory areas not occupied by the reloadable program are separated from second command instructions having absolute address parameters that refer to the memory area occupied by the reloadable program. It is possible for the reloadable program to be reloaded as a function of the application at any desired start address in the memory and to be adapted to that start address by the program execution unit. In particular, the need to create different reloadable program versions for possible application-related start addresses is dispensed with.

Abstract: A help system having a first generator (110) for dynamically generating a user profile data set. This user profile data set stores, in particular with reference to a time base (140), help topic data sets (130) and/or the frequency and/or the type of a user's access to utilization functions of a software program. The help system further includes a second generator (150) for generating a user help profile data set. In this user help profile data set (150), at least selected help topic data sets (130), or program branches therefor, are stored as a function of the access data recorded in the user profile data set (110). Based on the user help profile data set (150), at least one user-specific help startup page (120) is dynamically generated, which allows for activating the help topic data sets (130) associated with the user help profile data set (150).

Abstract: A chip card system, whose chip cards (AK, LK) have in each case at least one internal processor (P) and a non-volatile memory (S) at least for an operating system of the processor (P). There are a multiplicity of user chip cards (AKn) whose processors (P) can in each case execute user command instructions only after an activation, and there is at least one license chip card (LK), in whose non-volatile memory (S) a limitable number of activatable user chip cards (AKn) can be managed. By means of at least one read-write station (AKg) for chip cards (LK), the activation of the internal processor (P) is effected in a user chip card (AKi) if in the memory (S) of the license chip card (LK) the number of activatable user chip cards (AKn) is not yet exhausted. Thereafter, the number of activatable user chip cards (AKn) is decremented in the memory (S) of the license chip card (LK).
