Ethernet/IP Connection Problems —
following methods to troubleshoot:
UNIT IS POINT-TO-POINT CONNECTED TO A PC —
Ensure controller is powered on prior to configuration and
check Ethernet connection and PC Network Interface Card
(NIC).
NOTE: In addition to the following procedure, it may be nec-
essary to check the Ethernet connection and/or configure the
PC network board.
In Network Settings, open Local Area Connection Proper-
ties. Select Internet Protocol and click Properties. See Fig. 69.

The Internet Protocol Properties window is displayed.
• If no IP address is configured in the General and Alterna-
tive Configuration tabs, the unit IP address must be con-
figured to 169.254.xxx.xxx. Modify the unit IP address
and then restart the system.
• If the PC has a fixed IP address configured in one of the
two tabs (General and Alternative Configuration), the IP
address of the PC and the unit IP address must have the
system and sub-system fields in common. The last part
of the IP address is the host number and must be unique
on the sub-system. For example: Unit address —
172.30.101.11 and PC address — 172.30.101.182. In this
example, 172.30 corresponds to the network, and 101
corresponds to the sub-system. Carry out the necessary
modifications and try to access the unit again.
In the case of a problem, open a Windows command win-
dow (Start, Execute, type cmd and press Enter), then type the
command ping, followed by the unit IP address. In the exam-
ple shown in Fig. 70, the PC receives four positive responses
(replies).
