services: Maintenance and Diagnostics example: Upload of Diagnostic Data uploaded event data contain following information items (extract): • Fault code • Start date and time (occurrence of a fault) • End date and time (disappearance of a fault) • Subsystem (e.g. "brakes", "auxiliary", ... ) • Fault attributes according to UIC 556 leaflet • Short text message (max. 40 characters) • Count (number of faults of this code occurred so far) • Reference to environment data when configured Environment data are selected process variables being photographed at the occurrence of a fault. Absolute maximum limitations of environment data: • Up to 127 different data sets (16-bit words): Name, contents, unit • Pre- and Post-history, max. 255 samples where 1 sample is taken at the moment of the occurrence of the fault.
services: Fleet Management Fleet Management Point Locations Train Configurations Vehicle Selection by GPS From Fleet stock • number and location of attached locomotives • number of reachable coaches • locomotive attributes : locomotive identification Operational mode: (Leading or guided) ordering number locomotive status Pick car from train
