Method and device for the bus coupling of safety-relevant processes

Abstract: The invention proposes a method, in which, according to German Patent Application No. 10 2004 039932.8, a data set that is relevant for a safety-critical process is processed by means of at least two redundant processing channels (1, 2) according to identical laws for each safe protocol (14, 24) and the redundant safe protocols (14, 24) are assembled into a common safe protocol, in that each of the processing channels (1,2) accesses a common buffer register (30), wherein for each register location a write authorization is allocated only once, such that the common safe protocol is assembled proportionally by writing different portions of the corresponding safe protocols, wherein the contents of each register location of the buffer register (30) is read before the transfer of the common safe protocol from the buffer register (30) for the verification of the safe protocol formed in common from each of the redundant processing channels (1, 2), and which is characterized in that the safe protocol formed in common is released only as a reaction to a release for transmission by each redundant processing channel (1, 2).

Reihenklemme, insbesondere Trennklemme

Abstract: Dargestellt und beschrieben ist eine Reihenklemme, mit einem Klemmengehause (2), mit einer aus zwei Teilstucken (3, 4) bestehenden Stromschiene, mit zwei Leiteranschluselementen (5, 6) zum Anschliesen von je einem Leiter an ein Teilstuck (3, 4) der Stromschiene und mit einem schwenkbar im Klemmengehause (2) gelagerten Trennmesser (8), wobei die beiden Teilstucke (3, 4) in einer ersten Stellung des Trennmessers (8) miteinander verbunden und in einer zweiten Stellung des Trennmessers (8) voneinander getrennt sind und wobei die den Leiteranschluselementen (5, 6) abgewandten Enden (9, 10) der Teilstucke (3, 4) der Stromschiene derart abgebogen sind, das in der ersten Stellung des Trennmessers (8) das Ende (8) des ersten Teilstucks (3) der Stromschiene das Trennmesser (8) an einem oberen Kontaktbereich (11) und das Ende (9) des zweiten Teilstucks (4) der Stromschiene das Trennmesser (8) an einem unteren Kontaktbereich (12) kontaktiert.Bei der erfindungsgemasen Reihenklemme kann das Trennmesser (8) dadurch platzsparend, aber dennoch benutzerfreundlich und sicher geschaltet werden, das die Schwenkachse des Trennmessers (8) zwischen dem oberen Kontaktbereich (11) und dem unteren Kontaktbereich (12) angeordnet ist und das in der zweiten Stellung des Trennmessers (8) sowohl das Ende (9) des ersten Teilstucks (3) der Stromschiene von dem oberen Kontaktbereich (11) des Trennmessers (8) als auch das Ende (10) des zweiten Teilstucks (4) der Stromschiene von dem unteren ...

Digital level adjustment

Abstract: Apparatuses for level adjustment are essential to make adjustments to signals between integrated circuits having differing signal levels in electronic circuits. To assure signal adjustment for a large number of signals, as occur in parallel busses, an apparatus for level adjustment is used. This digital level adjustment uses the I/O cells already present in the integrated circuits with an externally wired pullup resistor and an internal digitally programmed or constructed signal connection for controlling output drivers.

Connection module with light display

Abstract: The disclosure relates to a connection module, including a plurality of connections for functional elements and a plurality of operating indicators. At least one of the operating indicators has a display element, and the display element has a base, which is disposed as a light guide and which has a light in-coupling surface and a light out-coupling surface.

Bidirectional, DC-isolated transmission channel

Abstract: Arrangement and method for the electrically isolated transmission of DC and AC signals. The signals can be transmitted in both directions using the same and only available DC-isolated channel. The arrangement comprises a first transmission and reception system (1), a DC transformer (4) in shorted mode, an operation amplifier arrangement (5) and a second transmission and reception system (2) with an event signal generator (9).
