Abstract: A method for providing access information for access to a field device for process automation is disclosed. The method includes the steps of determining, at a users operating device, at least one access information issued to the user for an access to at least one field device via the operating device, assigning, at the users operating device, a further user to the determined at least one access information, and sending an access permission comprising information relating to the determined at least one access information and to the further user assigned to the determined access information such that the determined at least one access information is provided to the further user based on the access permission.

Abstract: A method for manipulation-proof storage of payload data is provided, including: storing the payload data in a chain of data records; forming, for each data record in the chain, a current hash value at least using the payload data comprised and stored in the respective data record; storing, in the data record, a predecessor hash value that corresponds to a hash value of a preceding data record, such that in a first data record in the chain, a predetermined root hash value replaces the predecessor hash value; storing, in a persistent memory, a chain of hash values including the current hash value, the predecessor hash value, and the predetermined root hash value, such that content, once stored in the persistent memory, is no longer modifiable or removable from the persistent memory; and storing the data records in a reversible memory that is distinct from the persistent memory.

Abstract: There is provided a measuring system for acquiring measured values for fill level, measured values for pressure, measured values for flow, or measured values for density, the system including a central server and a plurality of measurement devices, which are connected to the server via the internet. A mobile device is also provided, which receives identification numbers of the measurement devices and transmits the identification numbers to the server, whereupon the server transmits the corresponding measurement data to the mobile device. As a result, it is possible to facilitate the assignment of measurement sites to a customer in a web portal.

Abstract: A mobile display device that selects a particular field device from a group of field devices and retrieves measurement data therefrom. The field device is selected by evaluating environment data which are captured by the display device without user input simplifying the measurement data display.
