Operating as an unmanaged layer-2 interface, the hardware transparently passes CIP (Common Industrial Protocol) message frames between PLC processors, distributed I\/O racks, and HMI panels. Integrated broadcast storm protection and full-duplex operation prevent packet collisions, optimizing communication bandwidth and preserving firmware flash compatibility across interconnected controller nodes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1783-US7T1F require software configuration or IP address assignment before operation?\u003c\/p\u003e\n\u003cp\u003eA: No, the 1783-US7T1F operates as an unmanaged layer-2 switch and functions instantly upon applying 24 VDC power and plugging in Ethernet media cables.\u003c\/p\u003e\n\u003cp\u003eQ: What type of fiber cable and connector is used for the fiber optic port on the 1783-US7T1F?\u003c\/p\u003e\n\u003cp\u003eA: The module uses standard multimode fiber optic cabling (62.5\/125 um or 50\/125 um) operating at 1300 nm wavelength, extending transmission distance up to 2 km.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply Terminal:\u003c\/strong\u003e Connect redundant 24 VDC power supply leads to the removable terminal block plug, ensuring proper wire polarity (+VDC, -VDC, and Frame Ground).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN-Rail Snap Installation:\u003c\/strong\u003e Securely latch the rear spring clip of the metal housing onto a standard 35 mm DIN rail inside the control cabinet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper Cabling Termination:\u003c\/strong\u003e Insert Category 5e or Category 6 industrial shielded twisted-pair (STP) cables into ports 1 through 7 until the RJ45 connectors lock in place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiber Optic Connection:\u003c\/strong\u003e Remove dust caps from the multimode fiber port and connect clean fiber jumpers, ensuring correct TX-to-RX cross-wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding \u0026amp; Shielding:\u003c\/strong\u003e Verify the enclosure ground terminal connects directly to the cabinet functional earth stud via a short, heavy-gauge grounding wire to suppress surge voltages and EMI.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52734378180888,"sku":"1783-US7T1F","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1783-US7T1F_Cocoai.jpg?v=1789870824","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1783-us7t1f-stratix-2000-unmanaged-ethernet-switch","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
