Abstract: The invention relates to a method for setting consistent values for a parameter in a network of distributed stations (10 to 14), and to a corresponding network subscriber station. In certain circumstances, it has been found that inconsistent entries can occur for the gap count parameter on the local bus in an IEEE 1394 network. If the bus management instance (25, 26) relies on the automatic behavior, as provided in the Standard, of all the network subscriber stations (10 to 11) to automatically set the maximum value of 63 after the second bus resetting process without any intermediate resetting of this parameter, this can lead to progressive resetting of the network, and this can result in blocking of the network. The problem is solved by immediate transmission of a parameter setting message for the critical network parameter once an inconsistency has been found.

Abstract: The invention relates to a method and a device for acquiring electronic information about transmission speeds between nodes of an acyclical network, in particular of an IEEE 1394 bus network, precisely one transmission link being present between in each case two of the nodes of the network, and a respective PHY transmission speed of the transmission link being determined by a minimum value of PHY speeds of the nodes of the network lying on the transmission link, in the case of the method the respective PHY transmission speed being determined for one subset of the transmission links in the network by acquiring the PHY speeds of the nodes lying on the transmission links and electronically acquiring minimum values of the PHY speeds; and the respective PHY transmission speed being electronically acquired for another subset of the transmission links, which is different from the one subset of transmission links, on the basis of one of the PHY speeds which have been determined for the nodes lying on the transmission

Abstract: The invention relates to a network subscriber station and to a method for operating a network subscriber station for a network of distributed stations, particularly a network of IEEE 1394 network subscriber stations, which are connected by means of a data bus. The network subscriber station comprises at least three memory areas for operation-dependent interface configuration data and pointer means, which comprise electronic pointers to the at least three memory areas, and driver means for handling electronic data in the at least three memory areas and for electronic data transfer between the at least three memory areas.

Abstract: A heating system having an electrical heating conductor arrangement which is integrated into a flexible heating body that can be connected to a supply voltage by a connecting cable and has a first conductor and an adjacent second conductor, placed in series with the first and separated from it by an insulating device, having a heating circuit formed by the heating conductor arrangement and further elements, including a control element for a heating current. A control circuit is connected to the control member for affecting the heating current and regulating the temperature. Monitoring is extended because the insulating device has a resistance characteristic which decreases with temperature.

Abstract: In a method of making a hardened sheet metal article, at least one pot-shaped depression is formed in a sheet metal blank. Thereafter, the sheet metal blank is hot formed in a press mold to a sheet metal article, and the sheet metal article is hardened. The press mold provides hereby a calibration of the depression to provide the final shape.
