Abstract: An actuator (4), having a communication unit (7) to set up a first radio link (6) to receive and transmit messages, and having a processing unit (9) to process messages. The actuator (4) is configured to process received messages in the processing unit (9) and to forward them via a second radio link (6). The actuator (4) is incorporated as a network node into a mesh network (1) and an optimum transmission path (32) between the network nodes is first determined for the transmission of messages.

Abstract: To improve the operator control capability of an actuating drive, switches are dispensed with and, instead, at least two rotary elements for rotational operator control are provided, arranged concentrically with respect to one another to be operatable using both hands and, in the process, are rotatable individually and independently of one another, preferably about a common axis of rotation. Rotational adjustment movements of the two rotary elements are transmitted by a magnetic coupling through a housing section, which is designed without apertures, of the actuating drive into an interior space of said actuating drive, such that, for reading out the magnetic fields, use can be made of conventional Hall sensors, and the housing of the actuating drive can be designed to be explosion-proof. In the event of failure of the rotary elements, the magnetic fields required for operator control are transmitted into the interior space using a magnetic pin for high operational reliability under all circumstances.
