When migrating code from \"UDEH\" models to the newer \"UDV\" series in GX Works2, execute a \"Change PLC Type\" operation and verify the Ethernet open ports setting, as the socket communication parameters may require minor adaptation due to the upgraded internal Ethernet chip capabilities.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eIn applications with high levels of industrial noise, the built-in Ethernet port must be configured with proper noise countermeasures.
