Note: The Windows Firewall is mainly designed to prevent inappropriate access from
external devices (e.g., via the Internet). The changes to the Windows Firewall settings
described in this document enable EtherNet/IP connections to be used by the CX-
Programmer. If the same computer is being used on a company network or other
network, confirm that the changes will not create security problems before proceeding
with the changes. The changes described in this document are required only when you
connect using EtherNet/IP through an Ethernet port. No changes are necessary if you
are connecting through any other port, such as a USB port.
