Cause and
correction
Assumed cause Correction Prevention
An out-of-range value was written by
an EtherNet/IP tag data link for a vari-
able with a specified range. A value
that does not specify an enumerator
was written by an EtherNet/IP tag
data link for an enumeration variable.
Correct the value that is written to the
variable with a specified range so that
the value is in the range. Correct the
value that is written to the enumera-
tion variable so that the value speci-
fies an enumerator.
Write values that are in range for vari-
ables with specified ranges. Write val-
ues that specify enumerators to
enumeration variables.

Precautions/
Remarks
• Write operations for out-of-range values or values that do not specify enumerators do not end normally.
• Write operations for in-range values or values that specify enumerators end normally.
Event name Packet Discarded Due to Full Reception Buffer Event code 84050000 hex
Meaning A packet was discarded.

Cause and
correction
Assumed cause Correction Prevention
A network convergence occurred. The load on the network is too high.
Check whether there are nodes that
send unnecessary broadcast frames
on the network and remove them.
After that, check that the received
number of frames has reduced in the
network statistical information.
Make sure that unnecessary broad-
cast frames are not sent on the net-
work. Do not connect the Ethernet
cable in a loop.
