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,, . . . Tlnn; FIG.,) 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).
