integration hurdles related to network packet congestion. During a recent high-speed sorting line upgrade, our engineering team observed intermittent communication dropouts between the amplifier and the plant PLC over an industrial Ethernet switch. Investigation revealed that heavy image data transfers via FTP combined with high-frequency PLC cyclic polling saturated a standard unmanaged switch. By migrating the network traffic to a managed switch with prioritized QoS settings dedicated to the \u003cstrong\u003eEtherNet\/IP\u003c\/strong\u003e loops and utilizing the microSD card for local bulk image caching, we stabilized data throughput and achieved continuous, zero-latency machine execution.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/IV4-G120.png?v=1789891482\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Keyence","offers":[{"title":"Default Title","offer_id":47534082326710,"sku":"IV4-G120","price":106.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/IV4-G120-3.jpg?v=1789891468","url":"https:\/\/www.plcsparehub.com\/products\/iv4-g120-keyence-iv4-series-ai-vision-sensor-amplifier-controller","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
