Safety device for multichannel controlling of a safety-related unit

Abstract: The invention relates to a safety device, comprising a first, microprocessor-controlled control unit and a second control unit, for multichannel controlling of a safety-related unit. The first microprocessor-controlled control unit has a signal generation unit for generating a first monitoring signal that indicates the current operating state of the first control unit. In addition, a switching unit drivable by the first and second control unit that can turn on the safety-related unit or run it into a secured state is provided. The second control unit has a monoflop that, in response to the monitoring signal, drives the switching unit in such a manner that the safety-related unit can be driven into a safe state in case of faulty operation of the first control unit. A device is associated with the first control unit for generating an enable signal for the second control unit.

Method and system for selecting a communications bus system as a function of an operating mode

Abstract: The invention relates to a communications entity for communications via a bus-oriented communications network with a control device ( 101 ) that is constructed to communicate via the communications network in response to a selection signal according to a first communications bus sub-system or according to a second communications bus sub-system, and a selection device ( 103 ) for generating the selection signal as a function of an operating mode of the communications entity, in order to select the first communications bus sub-system or the second communications bus sub-system.

Pluggable connector with pin guide e.g. for releasable connection of circuit board and conductor, has insulating body with at least one guide web for contact pin

Abstract: A pluggable connector is plugged on a plug connector containing a contact pin (2) and contains an insulation body (8) with a receptacle space (13) for each pluggable contact (12). The insulating body (8) contains in an insertion space of the contact pin at least one guide web (9) for the contact pin which extends in an axial direction relative to the position of the contact pin between two opposite facing arms (5,5a) of the contact spring.

Data transfer system for industrial control systems with diagnostic function for locating faults

Abstract: The system has a ring structure with unidirectional data transfer without terminal addressing to the terminals (5) which are connected into the ring structure, together with a control station (7) of higher standing. Faults, e.g. open circuits (8), are located from the effect on the next terminal in the transfer direction, which fails to receive any further valid input signals and transmits a diagnostic message with a defined value. The value of the message is incremented by each successive terminal, so that the control station can determine the fault location from the difference between the current and predefined message values.

Isolating clip, for a current rail, has a housing over two rail parts with a swing isolating blade and a plug contact at one rail part

Abstract: The isolating clip (1) has a housing (2), for a two-part current rail (3,4), with connections for each rail part. A swing isolating blade (5) has positions where the rail parts are linked together and are separated. A plug position (6) is electrically connected to one part-rail (3) to take a plug (10) with a plug housing (11) containing a conductor connection (12) for a pin contact (13), which is placed on the clip housing.
