Provided is a device for ensuring safe operation of a technical system configured to generate a smart contract including a condition to be fulfilled for safe operation of a technical system, to store smart contract data of the smart contract in a distributed ledger, and to determine if the technical system fulfills the condition using the smart contract.

Operational safety using a distributed ledger

A method for transmitting data from a first sub-system to a second sub-system includes the steps of providing a dataset by the first sub-system, the dataset having a data structure identifier and a data value; sending the dataset to the second sub-system; receiving the dataset by the second sub-system; checking whether complete assignment information regarding the data structure assigned to the data structure identifier is present in the second sub-system; recovering any missing assignment information from a communication broker in the event that the second sub-system does not contain complete assignment information; and determining the data structure on the basis of the data structure identifier and the assignment information. A corresponding system, a corresponding first sub-system, a corresponding second sub-system and a communication broker are also proposed.
