Packet Filter; Bootp Client - Omron sysmac NX102-9 Series Owner's Manual

1 Introduction
 Port Forward - IP Forward
The port forward function divides the built-in EtherNet IP port 1 network and the built-in EtherNet IP
port 2 network. To divide the networks, set IP Forward to Do not use. When it is set to Do not use,
IP packets other than the one addressed for the Controller are discarded. Refer to 5-1 TCP/IP Set-
tings Display for details. This function can only be used for the NX102 CPU Unit.
Additional Information
CIP routing is not be affected by the IP Forward setting.

Packet Filter

IP packets are filtered by the receive processing of the built-in EtherNet/IP ports. When the Packet Fil-
ter is enabled, only the Sysmac Studio that is installed on a computer with registered IP address can
connect to the CPU Unit, and connections from the Sysmac Studio on computers with unregistered IP
addresses can be restricted. This function can be used only for the NX102 CPU Unit.
Precautions for Correct Use Precautions for Correct Use
• NA-series and NS-series Programmable Terminals connections to the CPU Unit are restricted
if this function is enabled. Register the IP address of target device in the Packet Filter settings
to connect with above devices. Refer to Packet Filter (NX102 CPU Unit) for details on set-
tings.
• You cannot connect the Sysmac Studio installed on the computer with unregistered IP address
if this function is set to enable. Enable this function after confirming that the IP address of the
computer to allow connection is registered correctly in advance.
• You cannot connect the Sysmac Studio installed on the computer to the Controller in Direct
connection via Ethernet if this function is enabled. Select Controller - Communications
Setup to confirm that the connection method is Ethernet connection via hub.
• You can disable this function tentatively by starting in the Safe Mode in case you cannot con-
nect the Sysmac Studio on the computer because you forgot the registered IP address, etc.
Refer to the Troubleshooting When You Cannot Go Online from the Sysmac Studio in the NJ/
NX series Troubleshooting Manual (Cat. No. W503) for details.
