NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
In the case that there is a setting error or a communications error in the EtherNet/IP networks, the Sys-
mac Studio displays the error in the Troubleshooting Dialog Box.
Refer to
15-2 Troubleshooting on page 15-13 for the confirmation methods for errors and information on
errors.
The first time you establish an online connection between the Controller and the computer that runs the
Sysmac Studio version 1.10 or higher with Windows Firewall on the computer enabled, the dialog box
to confirm the connection may be displayed. If that occurs, make the following selection in the dialog
box.
• Unblock (on Windows XP/Vista)
• Allow access (on Windows 7)
If you make other selections than above, there are cases when transferring and monitoring the Ether-
Net/IP connection settings cannot properly be performed even if the online connection is successfully
established.
Disabling a part of Windows Firewall settings can resolve this.
(Refer to Method 1: Changing the Memory Configuration of the Structure Variable in the NJ/NX-series
CPU Unit on page A-61 for details.)
