A method for transmitting controlling control variables (36, 78) from a controller, for example a windfarm controller of a windfarm, to units, in particular at least one wind power installation and/or at least one energy store, of the windfarm, comprising the following steps: - determining a first controlling control variable component, - determining a second controlling control variable component with the 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 data packet with the first controlling control variable component from a first unit, - receiving the second data packet with the second controlling control variable component from a first unit, and - forming a controlling control variable from the first controlling control variable component and the second controlling control variable component in the first unit, - wherein the first data packet has a receiver address which is assigned to the first unit and to at least one further unit and wherein a controlling control variable component is transmitted with the first data packet, which is generally valid at the time of transmission for a plurality of or all units during control, and the second data packet has a receiver address which is assigned to at least the first unit, and wherein the second data packet contains a controlling control variable component, which is defined individually for a specific unit and accordingly is also received by the specific unit only, wherein first data packets with the first controlling control variable component are dispatched more frequently than second data packets with the second controlling control variable component, so that an update rate of the controlling control variable component of the individual units can continue to be implemented at a desired high frequency. - determining a first controlling control variable component, - determining a second controlling control variable component with the 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 data packet with the first controlling control variable component from a first unit, - receiving the second data packet with the second controlling control variable component from a first unit, and - forming a controlling control variable from the first controlling control variable component and the second controlling control variable component in the first unit, - wherein the first data packet has a receiver address which is assigned to the first unit and to at least one further unit and wherein a controlling control variable component is transmitted with the first data packet, which is generally valid at the time of transmission for a plurality of or all units during control, and the second data packet has a receiver address which is assigned to at least the first unit, and wherein the second data packet contains a controlling control variable component, which is defined individually for a specific unit and accordingly is also received by the specific unit only, wherein first data packets with the first controlling control variable component are dispatched more frequently than second data packets with the second controlling control variable component, so that an update rate of the controlling control variable component of the individual units can continue to be implemented at a desired high frequency.
