4 Determining IP Addresses
Additional Information
• Auto IP automatically assigns IP addresses in Windows 98 and later operating systems.
Unique IP addresses are automatically assigned from the address 169.254.0.0 to
169.254.255.255.
• If the IP address of the connected EtherNet/IP port is changed when the Sysmac Studio is
connected online via a built-in EtherNet/IP port, a timeout will occur in the Sysmac Studio. In
the case, switch the Sysmac Studio status to offline, change to the IP address of the con-
nected built-in EtherNet/IP port, and then switch back the Sysmac Studio status to online. This
will allow you to reconnect.
Precautions for Correct Use Precautions for Correct Use
If there is more than one node with the same IP address in the EtherNet/IP network, the built-in
EtherNet/IP port will connect to the node that is detected first. An IP Address Duplication Error
will not occur.
