List of diagnostics events with status and diagnostics message for activated condensed
status
A list of diagnostics events with status and diagnostics message for activated condensed
status is given in the following table. DIAGNOSTICS_EXTENSION and
DIAGNOSTICS_EXTENSION_2 are physical block parameters.
Different status and diagnostics messages can be allocated to individual diagnostics events
as per the following tables. The frame in which an allocation is possible is defined by the
group in the selection column. The following principle is used: in case of three-stage
diagnostics events of the MAINTENANCE group, the effect of the higher lever events can be
downgraded, but that of the lower level events cannot be upgraded.
