If an illegal value is set for the Ether-
Net/IP IP address in the server, cor-

it to operate normally if it is not.
Check the communications path to
the server and take corrective mea-
sures if there are any problems.

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).
