Abstract: A field device of automation technology having a function for checking quality of a network connection includes an operating electronics and at least one communication interface for connecting to a communication network having one or more network participants and for building a communication connection, wherein a communication stack and a PHY are associated with the communication interface, wherein the communication stack and the PHY are embodied continually to gain and to store communication information regarding the communication connection, wherein the operating electronics is embodied to read out communication information from the communication stack and from the PHY, and by means of an algorithm to subject the communication information to computation and based on the result of the computation to classify a communication state.

Abstract: A plain bearing includes an outer sliding-surface element and an inner sliding-surface element enclosed by the outer sliding-surface element. The outer sliding-surface element is divided along a substantially flat surface that includes the main axis of the sliding bearing and has, at least at one axial end, a radially encircling groove. A ring configured to fixedly hold together the divided outer sliding-surface element is inserted in the groove.

Abstract: An inductive rotational speed sensor, including: a coil body having a coil and connecting lines which at least partially extend axially or radially with respect to the coil windings; a casing formed from a plastics material and at least partially enclosing the coil body; and a fixing device for facilitating a configuration of the casing, the fixing device including: for radially extending connecting lines, a material core clearance in the casing so as to fix the electrical connecting lines at a mutual spacing when configuring the casing; or an anti-twist safeguard to prevent the coil body rotating relative to a tool used for configuring the casing while the latter is being configured, wherein the anti-twist safeguard partially protrudes from the casing, or extends at least up to an external surface of the casing. Also described is a related method.
