The invention relates to a method for sending target values to a wind farm regulator of a wind farm via a wind farm server, wherein the wind farm server has an input interface, and the input interface is used to receive target values for the wind farm regulator after a successful authentication by an access data record, wherein one of several predefined user identifiers is allocated in the wind farm server to each of several access data records, which correspond to predefined access data records, wherein the wind farm server is used to allocate the user identifier allocated to the access data record used for successful authentication before receiving the target value to a target value received from the input interface, and received target values with the allocated user identifier are output to the wind farm regulator. The invention further relates to a wind farm server and a system with a wind farm server.

Provided is a method for transmitting controlling control variables from a windfarm controller to units including at least one wind power installation or at least one energy store. The method include determining first and second controlling control variable components by the windfarm controller, outputting the first controlling control variable component in a first data packet, outputting the second controlling control variable component in a second data packet, receiving the first and second data packets by a first unit, and determining a controlling control variable from the first and second controlling control variable components. The first data packet has a receiver address which is assigned to the first unit and to at least one further unit, and the second data packet has a receiver address which is assigned to at least the first unit. Provided is a windfarm controller, a wind power installation and a windfarm configured to perform the method.

An industrial control system may receive data associated with at least one component within an industrial automation system. The industrial control system may then determine whether the data is associated with at least one of a plurality of data tags, such that the at least one of the plurality of data tags describes at least one characteristic of the data. The industrial control system may then broadcast the data and the at least one of the plurality of data tags in a data feed channel when the data is associated with the at least one of the plurality of data tags.
