The module architecture is typically deployed in configurations where FOUNDATION Fieldbus \/ Profibus PA connectivity abstraction and channel-to-channel isolation concepts are maintained at the system integration layer. These characteristics define signal segregation behavior between PCI Express host execution and V net physical bus transmission domains.\u003c\/p\u003e\n\u003ch3\u003eFrequentlyAskedQuestions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the VF702 support hot-swap removal during system operation?\u003cbr\u003eA: No hot-swap capability is specified. Removal requires system shutdown to avoid PCI Express bus and V net communication disruption.\u003c\/p\u003e\n\u003cp\u003eQ: What is the electrical isolation boundary of the VF702 interface?\u003cbr\u003eA: Isolation is implemented between PCI Express host domain and 10BASE-2 V net physical layer; external bus grounding must be managed at system level.\u003c\/p\u003e\n\u003cp\u003eQ: Can VF701 and VF702 operate on the same control bus?\u003cbr\u003eA: Yes. VF702 is backward compatible with VF701 and mixed operation on the same V net segment is supported.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eCoaxial cabling must follow 10BASE-2 topology rules using BNC T-connectors (Model YCB146). Proper 50 ohm termination must be applied at both ends of the bus segment to prevent signal reflection. Cable shielding must be grounded at designated points only to avoid ground loop formation. PCI Express insertion must be performed with power off, ensuring full seating in x1 to x16 compatible slots. BUS 1 and BUS 2 redundancy paths must be routed physically separated to reduce cross-coupling risk.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44153008128088,"sku":"VF702","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/VF702-3.jpg?v=1780025583","url":"https:\/\/www.industriaxplc.com\/products\/vf702-yokogawa-centum-vp-control-bus-interface-card","provider":"IndustriaX Limited","version":"1.0","type":"link"}
