Abstract: A system for recovering a server blade, in a multiple server blade computer, that is lost during a flash update operation on a service processor in the server blade. Because of the flash update failure, the lost server blade is unaware of its location on a management pathway, which in an exemplary form may be a midplane or a bus, which connects the server blade and a management module in a server blade chassis. The lost server blade puts a signal on the management pathway indicating that the flash failed. The signal is put on a special channel reserved for such messages. The management module receives the signal, and then determines which of the multiple server blades are lost due to the flash update failure.

Abstract: A method for detecting the level of a liquid in a container. The method includes applying a predetermined voltage to a level measuring electrode, disposed within the container, for a predetermined first period of time; then, discontinuing the application of the voltage and waiting a predetermined second period of time; and then measuring an electrode voltage at the level measuring electrode.

Abstract: The invention relates to a method for synchronizing nodes of a communication system comprising the following steps: receipt of a first synchronization message by a first node, whereby the first synchronization message contains a desired receipt time by a first node; correction of a time base of the first node, based on a deviation between an actual receipt time, determined as a result of the base time, and the desired receipt time.

Abstract: The invention relates to a synchronous clocked communication system, for example a distributed automation system, the stations of which can be arbitrary automation components and which are coupled to one another via a data network. Using the disclosed method for integrating decentralized input/output modules, these decentralized input/output modules can be linked into the synchronous clocked communication system in such a manner that they can use their characteristics unrestrictedly. Thus, in particular, the detection of input signals and the output of output signals is possible in a deterministic and synchronous manner in the decentralized input/output modules. In addition, the disclosed method enables input signals to be detected with an accuracy of less than the length of one communication cycle of the communication system and to support the switching of output signals in smaller time granularities than the length of one communication cycle which, in particular, finds use, e.g. for switching cams.

Abstract: A wind turbine rotor is decelerated and locked in a target rotational position in relation to rotation of the rotor about the rotor axis. The rotational position of the rotor in relation to the rotational axis is detected relative to at least one target rotational position. Once the rotor reaches one of the target rotational positions, the rotor is halted and automatically locked in the target rotational position.

Abstract: A voltage source converter with a line-side diode rectifier, a load-side inverter with an electronic circuit, a power supply for the electronic circuit, and a slim DC link with a DC link capacitor is described. The slim DC link connects a DC output side of the line-side diode rectifier with a DC input side of the load-side inverter. A buffer capacitor is connected across the power supply, and a decoupling diode and a current limiting circuit are electrically connected in series with the buffer capacitor. The serially connected buffer capacitor, decoupling diode and current limiting circuit are connected in parallel with the DC link capacitor. This arrangement results in a voltage source converter that has an improved service reliability even in unstable power grids, without adding circuit complexity to the line input.

Abstract: A data processing network includes a set of servers, at least one switch module to interconnect the servers, and a management module. The management module consults power state information stored in the network following a power transition and restores power to at least some of the servers and switch modules based on the power state information. The power state information prevents the management module from restoring power to servers and switch modules having incompatible communication protocols. In one embodiment, the plurality of servers and the switch modules are hot-swappable modules that are all inserted into a single chassis. In this embodiment, the server modules and at least one switch module share selected resources of the network including system power. The switch modules and servers may employ Ethernet, fiber channel, optical, and serial communication protocols.

Abstract: The present invention is directed to a method of operation and a control program for a central unit (e.g., CPU) in an automation system repeatedly executing a control program that is stored in the central unit and comprises at least two subprograms. A single instance of execution occurs within a cycle time which is stipulated by the control program. The central unit executes only one of the subprograms—the activated subprogram—at a time. The cycle time is independent of the activated subprogram, is shorter than the time required in order to execute all of the subprograms, and is at least as long as the longest time period required in order to execute one of the subprograms once.

Abstract: In a chassis based server a programmed processor determines the fabric type that allows the maximum numbers of processor modules and switches to be powered on. The processor then allows power to be applied to processor modules and switches whose fabric type is the same as the determined fabric type.

Abstract: The invention relates to a synchronous, clocked communication system, for example a distributed automation system, the stations of which can be arbitrary automation components which are coupled to one another via a data network (1) for the purpose of mutual data exchange. In this arrangement, all possible bus systems such as, e.g. field bus, professional field bus, Ethernet, industrial Ethernet etc. are available for use as the data network (1) of the communication system. One station of this communication system is designated as timing generator and ensures the distribution and maintenance of the communication clock used to and by all stations. The timing generator can also introduce a relative clock (9) in the entire communication system at all stations via the same mechanism. This station is thus also the master of the relative clock (9) or the applicable relative time (16).

Abstract: When a blade and/or interconnect device is inserted into the chassis of a powered or live server the procedure is known as hot-plugging. Before power is applied to the hot-plugged blade and/or interconnect device the fabric type of already installed blades and/or interconnect devices is correlated with fabric types of newly hot-plugged blade and/or interconnect device. Depending upon results of the correlation, power to the hot-plugged blade and/or interconnect device is allowed or denied.

Abstract: Method of operation and control program for a central unit in an automation system, and the central unit in an automation system and the automation system itself. A central unit (e.g., CPU) (1) in an automation system repeatedly executes a control program (8) that is stored in the central unit (1) and comprises at least two subprograms (TP1-TP3). A single instance of execution occurs within a cycle time (T) which is stipulated by the control program (8). The central unit (1) executes only one of the subprograms (TP1-TP3)—the activated subprogram (TP1-TP3)—at a time. The cycle time (T) is independent of the activated subprogram (TP1-TP3), is shorter than the time (t1+ . . . +t8) required in order to execute all of the subprograms (TP1-TP3), and is at least as long as the longest of the times (T1-T3) required in order to execute one of the subprograms (TP1-TP3) once.
