Techniques and architectures enable a wireless communications system to receive and deliver a message for which a user of a mobile device has specified which among multiple devices, all assigned the same phone number as one another, is to receive the message. The mobile device may be the sender or the receiver of the message. The message may be a scheduled message to be delivered on a particular date and time to a contact in an address book of the sender.

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.

Disclosed is a message processing unit provided in a PLC system including a master and a plurality of slaves. The message processing unit is provided to each of the slaves and includes a first filter configured to receive a message transmitted from the master and to determine whether the message is a broadcast message, a second filter configured to receive the message delivered from the first filter and to determine whether the message is a message-to-be-processed, and a processor configured to process the message he delivered from the first filter or the second filter.
