A-4 Precautions When Using the OMRON
EtherNet/IP with CX-ConfiguratorFDT
When you use OMRON EtherNet/IP for the CX-ConfiguratorFDT and the CPU Unit or Industrial PC,
and communicate with the following connection methods, an online connection may not be established
depending on the Windows firewall settings.
• Ethernet I/F
• NJ/NX/NY Series Ethernet Direct I/F
• NJ/NX Series USB Port
In such cases, allow access to the network in a Windows firewall security dialog box that is displayed
when the CX-ConfiguratorFDT connects to it for the first time, or change the Windows firewall settings
to allow communications through the Ethernet port.
Better firewall security for Wndows XP (SP2 or higher), Wndows Vista, and Windows 7 higher has in-
creased the restrictions for data communications.
The following gives the procedure to make the Windows firewall settings for each OS.
