Tab.3/10:Diagnostic bytes 30 Ū 62: Channel−related diagnosis (details in section 3.5.5)
The following applies to entries in the diagnostic bytes
30Ū62 (channel−
related diagnosis):
Entries must be in ascending order by module number
without gaps: The entries must always be in the same
sequence as the module n
umbers, irrespective of the time
sequence of the diagnostic messages (if necessary, the
entries with large module numbers will be shifted).
In the case of module−oriented and ch
annel−oriented
faults on a module, only the module−oriented diagnostic
message will be entered.
If there are several channel−oriented faults on a mod
ule,
only the diagnostic message of the channel with the
lowest channel number will be entered.
A maximum of 11 diagnostic messages can be processed.
