Abstract: A method, computer program product and system for streaming measurement data that includes a number of provider devices configured to provide a number of data streams that each include multiple structured data records indicative of measurement data obtained from a number of data sources of an industrial facility, a registry device configured to store, for each data stream, a semantics specification indicative of a semantics of the structured data records of the data stream; and a number of consumer devices configured to, for at least one data stream, (i) receive the data stream provided by the corresponding provider device, (ii) obtain the measurement data from the structured data records based on the semantics specification of the received data stream stored in the registry device, and (iii) consume the obtained measurement data, such that versatility is increased when multiple provider devices operate according to different semantics.

Abstract: An access control method and industrial network for field automation which includes a plurality of network nodes that host a blockchain storing a plurality of confirmed transactions, exchange an unconfirmed transaction and add the unconfirmed transaction to the blockchain as a confirmed transaction of the confirmed transactions only if a consensus is reached between the plurality of network nodes, wherein the plurality of network nodes include a trusted backbone of the industrial network, and the confirmed transactions stored by the blockchain include a confirmed connection transaction that is authorized by the trusted backbone, indicative of a connecting device and descriptive of a right of the connecting device to access the industrial network, where a provider network node grants a connecting device access to a network resource if the confirmed connection transaction is stored in the blockchain and an amount of cryptocurrency is transferred to the provider network node.
