Troubleshooting Chapter 7
Viewing and Clearing Events The adapter has an event queue to record significant events that occur in the
operation of the adapter. 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 20-
HIM-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 non-volatile. Eventually the event queue will
become full, since its contents are retained through adapter 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 adapter will not
generate a fault to indicate that the event queue was corrupted.
Resetting the adapter 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.

60 Gateway Act 1
Gateway Act 2
Gateway Act 3
Gateway Act 4 Value of each byte in the adapter’s present gateway address. A value of ‘0’ appears if the adapter does not currently
have a gateway address.
61 Net Rx Overruns A count of the number of receive buffer overruns reported by the Ethernet hardware.
62 Net Rx Packets A count of the number of Ethernet packets that the adapter has received.
63 Net Rx Errors A count of the number of receive errors reported by the Ethernet hardware.
64 Net Tx Packets A count of the number of Ethernet packets that the adapter has sent.
65 Net Tx Errors A count of the number of transmit errors reported by the Ethernet hardware.
66 Last TCP Reset The last reason that the adapter reset or rejected a TCP/IP connection.
67 Missed IO Pkts A count of the number of incoming I/O connection packets that the adapter did not receive.
68 Net Addr Sw The present value of the adapter IP address switches.
