A device for adding equipment data of a piece of equipment into a distributed database system includes a first communication interface designed to receive database configuration information from the distributed database system, a second communication interface coupled to the piece of equipment and designed to receive equipment data a configuration module designed to select at least one configuration parameter for configuring a data providing module, test at least one selected configuration parameter on the basis of the database configuration information, output the test result, and configure the data providing module, an identification module designed to provide identification information, a registration module designed to register the piece of equipment on the basis of the identification information for the distributed database system, and a data providing module designed to add the equipment data with respect to the identification information into the distributed database.

Device and method for adding equipment data into a distributed database system

Provided is a method for operating a field device. The field device is configured for interacting with a control device. According to the method, a base key is received from a key generation device. A current constraint parameter relating to a predefined operating constraint for operating the field device is determined. A key is generated based on the base key and the current constraint parameter. The field device interacts with the control device using the generated key.

Constrained operation of a field device

A method and a system for sending data to and/or retrieving data from a decentralized distributed database is provided. The method involves retrieving a transformation rule from a data library by the sending/retrieving system, wherein the transformation rule defines a transformation of data in a system-specific data structure into a database-specific data structure or vice versa. Sending and retrieving data involves a transformation of the data structure according to the transformation rule. The method ensures for example correctness, reusability, and/or forward and backward compatibility of data tracked in the decentralized distributed database.

Exchanging data with a decentralized distributed database

In a computer-implemented method for storing data in a network of linked computing units () using a distributed transaction database (GDB), a distributed transaction database (GDB) in the form of a distributed graph database formed using nodes is used, and data is stored in at least one node (N) of the graph database, wherein the node (N) is stored using a real sub-quantity of the computing units () of the network. The computer program product can be loaded directly into a storage device of an electronic computing unit () and has program means in order to early out the steps of the method when the program is ran in a computing unit. The network of linked computing units () stores a distributed transaction database (GDB) in the form of a distributed graph database comprising nodes (N) in which data is stored according to such a method.

Various examples of the disclosure generally pertain to storing, in a distributed ledger and in association with one or more transactions, one or more identifiers of owners of respective smart contracts. Various examples of the disclosure relate to deleting transactions associated with a given party as owner upon receiving a withdrawal request of the given party.
