29 Nov 1998TL;DR: In this paper, a self-diagnosis of substantially sporadic faults in a serial network which connects a number of subscribers together to a central diagnosis apparatus is characterized in that arranged decentrally at each subscriber (Tln 1,... Tlnn; FIG. 5 ) at given fault-relevant locations in its protocol stack are fault detectors (FD) which transmit their test results to a diagnosis and report manager (DRM) which from the individual test results of all fault detectors produces a fault picture which it preaddresses for transmission thereof.
Abstract: An apparatus for self-diagnosis of substantially sporadic faults in a serial network which connects a number of subscribers together to a central diagnosis apparatus is characterised in that arranged decentrally at each subscriber (Tln 1 , . . . Tlnn; FIG. 5 ) at given fault-relevant locations in its protocol stack are fault detectors (FD) which transmit their test results to a diagnosis and report manager (DRM) which from the individual test results of all fault detectors produces a fault picture which it preaddresses for transmission thereof insofar as, for each fault picture to be transmitted to a central diagnosis apparatus (DE) for the purposes of evaluation there, it generates an address (ID-ADR) by means of which it actuates an ID-transmitting-receiving buffer memory (FDSEP) in which it provides for intermediate storage of the fault pictures associated with the addresses and reads them out again in time-displaced relationship for their transmission to the central diagnosis apparatus by way of the transmission network (UN).

TL;DR: fieldbus component comprising a field bus protocol abarbeitende a data link layer (70; 72-76) and a physical layer (60-64) characterized in that the physical layer is designed for a high-speed data transmission according to the standard IEEE 802.3u of Fast-Ethernet.
Abstract: fieldbus component comprising a field bus protocol abarbeitende a data link layer (70; 72-76) and a physical layer (60-64) characterized in that the physical layer (60-64) is designed for a high-speed data transmission according to the standard IEEE 802.3u of the fast Ethernets that a data link layer (70; 72-74; 76) and the physical layer (60-64) connecting interface (65) is provided that a matching layer (71) is provided, which comprising a field bus protocol abarbeitenden data link layer (70; 72-74; 76) formed on the according to the standard IEEE 802.3u of Fast-Ethernet physical layer (60-64) adjusts by of the data link layer (70; 72-74; 76) coming data to a data to be transmitted frames are composed of from the physical layer (60-64) is processable.
