Yokogawa VI702 Vnet/IP Interface Card CENTUM VP
VI702
The Yokogawa VI702 is a high-speed Vnet/IP interface control bus card designed to connect PC/AT compatible computers to the CENTUM VP control network. It features a 1 Gbps full duplex communication speed and seamless compatibility with existing VI701 systems for industrial process automation.
The Yokogawa VI702 (Model VI702 Vnet/IP Interface Card) is an essential hardware component engineered to bridge PC/AT compatible computers with the advanced Yokogawa CENTUM VP distributed control system (DCS) network. By slotting directly into a PCI Express expansion slot of a control computer, this interface card establishes a secure and high-performance link to the robust Vnet/IP control bus.
Key Architectural Features & Performance:
-
High-Speed Communication: Delivers a blazing 1 Gbps full duplex transmission rate, ensuring real-time data exchange, low latency, and high bandwidth across critical plant operations.
-
PCI Express Integration: Compliant with PCI Express CEM Specification 1.0a (x1, 2.5 GT/s signaling), compatible with any standard PCI Express slot ranging from x1 to x16.
-
Robust Physical Connectivity: Utilizes standard RJ45 connectors optimized for Enhanced Category 5 (CAT5e) UTP cables, supporting a maximum distance of up to 100 meters between the interface card and Layer 2 network switches.
Full Backward Compatibility with VI701: Designed for seamless system upgrades and maintenance, the VI702 Vnet/IP interface is fully compatible with the older VI701 card. Engineers can install VI701 and VI702 cards together within the same control bus network. Furthermore, domain and station numbers for the VI702 are configured using the exact same methods as its predecessor, minimizing engineering overhead and configuration time.
Operational Monitoring & Compliance: Equipped with clear diagnostic LED indicators on the front panel—including RDY (card normal status), RCV (bus signal detection), and SND (signal transmission)—operators can quickly verify real-time communication health. The card complies with rigorous international electromagnetic compatibility (EMC) standards, featuring CE, C-Tick, and KC markings for safe global deployment in heavy industrial automation environments.
