Abstract: A user input module for an automation engineering field device comprising: at least one user input element without haptic feedback; an electronic unit configured to detect instances of operation of the user input elements, to prompt a first feedback for a user when an instance of operation of one of the user input elements is detected, which instance of operation lasts in particular for longer than a first prescribed period, and to prompt a second feedback for the user when an instance of operation of one of the user input elements is detected, which instance of operation lasts for longer than a second prescribed period, wherein the second period is longer than the first period, and an automation engineering field device that has the user input module according to the invention.

Abstract: A method for wireless data transmission between first and second transmission participants, wherein for wireless data transmission between the first and second participants alternately a first protocol and a second protocol are used, wherein the first protocol serves for unidirectional data transmission and the second protocol for bidirectional data transmission.

Abstract: A method for servicing a field device of process automation technology. The data exchanged between the field device and a servicing program is by means of at least one protocol, which has basic commands, via which basic functions of the field device can be invoked. Each field device which is compatible with the protocol has these basic functions available to it, and wherein only basic commands of the protocol are used to transfer data between the servicing program and the field device.

Abstract: A synchronous data transmission system for transmission of data between two communication partners, of which one serves as a transmitter and one as a receiver, comprising a clock signal producer which produces a transmission clock signal with a transmission clock signal rate from the transmitter to the receiver, which during the occurrence of one of the events equals an event specific transmission clock signal rate associated with the arising event and during an event free period of time equals a fundamental clock rate different of all event specific transmission clock signal rates.

Abstract: A method for servicing a field device having a first wireless transmission module, preferably a transponder. An adapter is provided, which has a corresponding second wireless transmission module, preferably a reading device, for querying the transponder. The field device has, furthermore, a first communication interface for communication via a fieldbus, preferably a wired fieldbus, wherein the adapter has a second communication interface likewise for communication via the fieldbus, preferably a wired fieldbus. Data stored in a memory unit of the field device are wirelessly retrieved and transmitted to the adapter by means of the first transmission module and by means of the second transmission module, wherein the adapter is connected with a service device, and wherein by means of the retrieved data a connection is established between the field device and the service device via the field bus.

Abstract: In a measuring device for automation technology with single-hand servicing, a housing closable with a lid is provided. Arranged at an edge of the lid is a movable ring element, which is mounted to be slightly shiftable parallel to the longitudinal axis of the lid and to be rotatable about the longitudinal axis of the lid. On the lid are sensors, which serve for registering rotary and linear movement of the ring element, via which a display unit is operated.
