The interface has an event queue to record significant events that occur in the
operation of the interface. When such an event occurs, an entry consisting of
the numeric code of the event and a time stamp is put into the event queue. You
can view the event queue using CCW. The event queue cannot be viewed using
the HIM.
The event queue can contain up to 100 entries, which are stored in nonvolatile
storage (NVS). Eventually the event queue becomes full, since its contents are
retained through power cycles and resets. At that point, a new entry replaces
the oldest entry. Only an event queue clear operation clears the event queue
contents.
Many events in the event queue occur under normal operation. If you
encounter unexpected communication problems, the events can help you or
Allen-Bradley® personnel troubleshoot the problem. The following events can
appear in the event queue.

for dynamic (runtime) memory allocations.
Description
The interface established a network link on its ENET1
network port.
The interface lost the network link on its ENET1 network
port.

network port.
The interface lost the network link on its ENET2 network
port.
Another device having the same IP address as the
interface was detected on the network.
The interface network address configuration parameters
are invalid, or the network address that is provided by
the BOOTP or DHCP server is invalid.
The interface received a response to its BOOTP request.
The interface received a response to its DHCP request.
The interface renewed its network address lease with
the DHCP Server.
