POINT POINT POINT
(1) When the IP address duplication is not checked
(a) When the IP address of the GOT is set to 192.168.0.18, the IP address duplication check
is not performed.
(b) Depending on the device to connect with the GOT, the IP address duplication check may
not be performed.
(2) When the GOT is added to the network in which a device with the same IP address as
that of the GOT exists
GOT goes into offline status and the following dialog appears.
When the IP address is duplicated, the FA transparent function cannot be used regardless of
the communication route.
• When correcting the same IP address of other device as that of GOT
After correcting the same IP address of other device as that of GOT, touch the [Reboot
GOT] button to restart the GOT.
• When changing the IP address of GOT
Touch the [Clear IP Address] button to clear the IP address of the GOT.
After touching the [Reboot GOT] button to restart the GOT, change the IP address of the
GOT by the utility.
(3) Precautions for selecting [Do not maintain a network connection]
When selecting [Do not maintain a network connection], the GOT is disconnected from the
network at the addition of a device with the same IP address as the GOT.
Therefore, there is a possibility that the running GOT cannot be communicated by IP address
setting mistakes or intended actions by malicious users, and the system control may be
influenced by those errors.
Please change the setting of [Behavior of duplicate IPs] after carefully examining the
necessity.
(4) Precautions for using a switching hub compatible with the spanning tree protocol
For the switching hub port connected with the GOT, configure the setting (PortFast or others)
that makes the GOT be ready for communications (forwarding state). The setting is required
to make sure that the delay right after the connection by the spanning tree protocol does not
occur.
Without the setting, the Ethernet IP address duplication is not correctly detected.
Additionally, the GOT may not be connected to Ethernet correctly.
For the setting that makes the GOT be ready for communications (forwarding state), refer to
the user's manual for the switching hub used.
