Viewing and Clearing
Events
The option module has an event queue to record significant events that occur in
the operation of the module. When such an event occurs, an entry consisting of
the event’s numeric code and a timestamp is put into the event queue. You can
view the event queue with any of these drive configuration tools:
• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM
• Connected Components Workbench software, version 1.02 or later
• DriveExplorer software, version 6.01 or later
• DriveExecutive software, version 5.01 or later
For details on viewing and clearing events with the HIM, see the PowerFlex 20HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication
20HIM-UM001.
The event queue can contain up to 32 entries, which are stored in an EEPROM
chip—making the event queue nonvolatile. Eventually the event queue will
become full, since its contents are retained through option module power cycles
and resets. At that point, a new entry replaces the oldest entry. Only an event
queue clear operation or the corruption of the EEPROM group containing the
event queue will clear the event queue contents. In the latter case, the option
module will not generate a fault to indicate that the event queue was corrupted.
Resetting the option module to defaults has no effect on the event queue, other
than to log a Code 58 ‘Module Defaulted’ event.
Many events in the event queue occur under normal operation. If you encounter
unexpected communications problems, the events may help you or Allen-Bradley
personnel troubleshoot the problem. The following events may appear in the
event queue.

Description
Option Module Events
1
No Event
Text displayed in an empty event queue entry.
2
Device Power Up
Power was applied to the option module.
3
Device Reset
The option module was reset.
4

DPI Bus Off
A bus-off condition was detected on DPI.
9
DPI Ping Timeout
A ping message was not received on DPI within the specified time.
10
DPI Port Invalid
The option module was not connected to a valid port on a DPI product.
11
DPI Port Changed
The DPI port changed after startup.
12
DPI Host Reset
