A system including a plurality of networked machines managed by a management system is disclosed. In the system, the machines and the management system each form nodes of a distributed ledger network. Further, the machines each have machine properties stored as a data record on a memory of the machine. Additionally, the machines each also have a standardized smart contract on the same or a further memory. The management system includes an integration contract configured to match standardized smart contracts to previous smart contracts already available in the distributed ledger network and transform the standardized smart contracts into the distributed ledger network. Further, a transformed smart contract controls a collaboration model between the networked machines and is executed so as to be implemented in the distributed ledger network computer.

Integration of a machine into an existing distributed ledger network

An automation system with a plurality of communicatively connected automation devices is disclosed. One of the connected automations devices serves as a domain controller and holds centrally in a memory data required for operation for the automation system and the automation devices. Hitherto frequently occurring multiple storage of such data is eliminated, the data is available at a central location for access by all the automation devices, and the domain controller, as a central data server, ensures consistency of the data administered and provided by it, which also permits access optimizations, such as e.g. device-, access- or structure-dependent temporary storage strategies.

Automation system and method for operating such an automation system

A method for operating a process plant, in which a number of alarm notifications for indicating non-compliant operating events of the process plant are generated at process level. Alarm notifications which can be generated during the operation of the process plant are defined. At least a number of the generatable alarm notifications are assigned, in each case at least a first value or a second value as a dependency value. A current process state of the process plant is determined and depending on the determined process state, those alarm notifications to which the first value was assigned as a dependency value are not indicated.
