Under days data transmission network with diagnostic apparatus

摘要

Under days data transmission network (1), especially in underground mining, for the cross-linking of purely control units (se), operating units (b) and actuator units (a), which, by means of frequency modulation of a field bus - communication network signal (3) communicate with each other, wherein a diagnostic unit (d) for fault analysis and / or monitoring of the frequency-modulated signal in the underground data transmission network (1) may be incorporated, characterized in that the diagnostic apparatus (d) a frequency-modulated signal errored evaluates and repaired, in such a way that erroneous signals are filtered out and the repair to the respective to be applied individually or in the respective inserted data transmission network is modified.
