Event name BOOTP Server Error Event code 84E1 0000 hex
Meaning Connection with the BOOTP server failed.

Effects User program Continues. Operation Requests to the BOOTP server will continue until there is
a response from the BOOTP server. During that time,
communications using BOOTP are not possible. Error
responses are returned to all communications requests.
Data refreshing with the PLC Function Module will con-
tinue. The IP address of the EtherNet/IP port that was
specified by the BOOTP server was an illegal value. Oper-
ation is performed with the illegal default IP address
(192.168.250.node_address).

Server setting error (The acquired IP
address is illegal.) If an illegal value is set for the Ether-
Net/IP IP address in the server, cor-
rect it. Set the EtherNet/IP addresses in the
server so that there are no illegal val-
ues.
Server is down. Check if the server at the remote con-
nection is operating normally and set
it to operate normally if it is not. Check to make sure that the server at
the remote connection is operating
normally.
An error occurred in the communica-
tions path. Check the communications path to
the server and take corrective mea-
sures if there are any problems. None

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.
Attached
information None
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.
