Abstract: The invention relates to a method for operating a network management station that exchanges data with the network devices connected to said station via bus connections by means of the SNMP protocol. An agent is integrated in each network device, said agent detecting the state of the network device and also being able to carry out adjustments or trigger actions in said device, wherein said agent communicates with the network management station via SET and GET commands. Furthermore, an error detection and/or an error notification between the network management station and the respective agents is carried out via the SNMP protocol. The method is characterized in that a further data exchange between the network management station and the respective agents is carried in addition to the data exchange provided according to the SNMP protocol in order to exchange further data content between the network management station and the respective agents using said further data exchange.

Abstract: The invention relates to a method for running a network, in particular an Ethernet network with redundancy properties, wherein the network has a ring network topology, in which network devices are connected to each other with the data ports thereof via data lines and exchange control data and user data by means of protocols via the data lines, wherein the protocols prevent the transmission of network traffic via certain data ports of individual network devices with the exception of network traffic for controlling and/or monitoring the media redundancy, in order to avoid an endless circulation of network traffic in physical loops of the network, wherein it is provided according to the invention that at least two different protocols are executed parallel to each other in the network on the network devices, wherein the parallel operation of the at least two redundancy protocols is enabled by the fact that the control over the data ports to be blocked is assigned to an individual redundancy, or the parameters for

Abstract: An electrical connector has an elongated generally circular-section socket part centered on an axis and an elongated generally circular-section plug part centered on an axis and coaxially fittable in the socket part in an assembled position of the connector. An axially projecting latch tab formed with a radially inwardly open hole on one of the parts can engage and lock on a radially projecting latch lug on the other of the parts and fittable in the hole in the assembled position of the connector. The lug has an angularly extending angled ramp and an axially extending ramp. The latch tab is axially and angularly engageable with the ramps.

Abstract: A contact (1) for a plug or socket of a quick-connect plug connection, the contact (1) being held mounted in a contact holder (2) having a region for press-fit gripping a conductor, a wire holder (7) having at least one wire seat (7.1) for the end of a wire and the contact (1) engages the wire in the wire seat (7.1), where according to the invention the contact (1) has at least two press-fit arms (1.4) of curved and/or polygonal section that contact the wire generally axially.

Abstract: The invention relates to a sealing element (7) which can be fastened on at least one conductor (2, 4, 6) of at least one line (1, 3, 5) or the line (1, 3, 5) itself and which can be inserted into a housing (12). According to the invention, the sealing element (7) is provided with openings (8, 9, 10) for receiving the conductors (2, 4, 6). The sealing element (7) can be inserted, with or without the mating contact or line (1, 3, 5), into the housing and fastened therein before or after it is positioned on the conductors (2, 4, 6).

Abstract: The invention relates to a plug connector for exterior application, in particular, for the electrical connection of solar panels, comprising a plug (16) with a plug housing (14), comprising at least one contact pin (3), or contact sleeve (13) and a coupling (1) comprising a coupling housing (2), with at least one contact sleeve (13) or contact pin (3), whereby the plug (16) and the contact pin (3) may be at least partly plugged into the coupling (1) and the contact sleeve (13). The contact pin (3) and the contact sleeve (13) may each be connected to at least one cable conductor (12) of a cable (4) and the plug (16) and the coupling (1) each comprise a locking piece of a locking unit for fixing the plug (16) and coupling (1) to each other.
