Abstract: It is provided to implement a different number of logical slaves in a field device for use in an AS interface network as a function of the assigned address, which slaves may be addressed using the assigned address in the standard or in the expanded addressing mode. Thus, in a field device, it is possible to provide slaves having different profiles, via which different data types may be exchanged. Furthermore, a method is provided, with which a field device having different slaves is able to be addressed in a simple manner while avoiding double addressing.

Abstract: At least one embodiment of the invention relates to a fieldbus system, in particular for use in an explosion-hazard area. The fieldbus system, in at least one embodiment, has a plurality of bus line sections with bus lines; an isolating element, by which in each case two of the plurality of bus line sections are coupled to one another and which galvanically isolates the bus lines of the two bus line sections from one another such that this prevents any direct current flowing between the bus lines of the two bus line sections and communication signals are transmitted between the two bus line sections; and a supply source for each of the bus line sections, in order to provide an electrical power supply for field devices which can be connected to the respective bus line section.

Abstract: A process and a device for increasing interference suppression, especially in optical proximity switches, with an optical transmitter emitting an optical pulse train (1), an optical receiver emitting a measuring signal (2) and a control and evaluation unit controlling the optical transmitter and evaluating measuring signal (2), in which the measuring signal (2) of the optical receiver includes a superposition of a constantly emitted interference background (4) and a measuring pulse (6) emitted when receiving an optical pulse (5), and in which the measuring signal (2) of the optical receiver is evaluated by the control and evaluation unit in a signal interval (8) during a measuring pulse (6) and in at least one background interval (9) outside measuring pulse (6). The increase of the interference suppression is assured in that the evaluation is interrupted by gaps (11, 12) before and after the signal intervals (8) or background intervals (9).

Abstract: An electronic switching device such as an inductive proximity switch includes an externally influenced oscillator detector with its output connected to a switching amplifier. An electronic switch connected to the output of the switching amplifier responds to the amplifier signal and controls a state indicator. Upon the influence state of the detector crossing a predetermined threshold, the switching state of the electronic switch is reversed, and the detection state of the oscillator is reflected in switching states of the electronic switch and indicated by the state indicator. A second state indicator indicates whether or not the reading from the oscillator is in a "safe range" in which variations in ambient conditions cannot cause a false reading.
