Displaying the diagnostic events
The CPU provides a diagnostic buffer that contains an entry for each diagnostic event, such
as transition of the CPU operating mode or errors detected by the CPU or modules. To
access the diagnostic buffer, you must be online.
Each entry includes a date and time the event occurred, an event category, and an event
description. The entries are displayed in chronological order, with the most recent event at
the top.
While the CPU maintains power, up to
50 most recent events are available in
this log. When the log is full, a new
event replaces the oldest event in the
log.
When power is lost, the ten most
recent events are saved.
