Details：
The Yokogawa VI702 is a high-performance, PCI Express-based Vnet/IP Interface Card, exclusively engineered to enable seamless and deterministic communication between PC/AT-compatible computers (e.g., Human Interface Stations, HIS) and Yokogawa’s CENTUM VP and ProSafe-RS Distributed Control Systems (DCS). As a critical connectivity component for Yokogawa’s proprietary Vnet/IP real-time industrial Ethernet network, it facilitates high-speed data exchange between field control stations (FCS), operator workstations, and other system peripherals—making it indispensable for industries like petrochemicals, power generation, and chemical processing where real-time process monitoring and control are mission-critical .
-----Core Specifications
The Yokogawa VI702 is classified as a gigabit industrial network interface card, optimized for low-latency, high-reliability communication in DCS environments. Its core specifications are tailored to integrate seamlessly with Yokogawa’s control systems while aligning with standard network infrastructure.
Network & Communication Specifications
Network Protocol: Dedicated to Yokogawa’s Vnet/IP protocol—a real-time Ethernet standard designed for industrial control, ensuring deterministic data transmission (critical for time-sensitive process signals) .
Communication Speed: Supports 1 Gbps full-duplex transmission, enabling rapid exchange of large-volume process data (e.g., multiple analog/digital signals from field sensors) without latency .
Transmission Standard: Complies with 1000Base-T Ethernet, compatible with widely deployed twisted-pair cabling infrastructure .
Physical Connection: Features a standard RJ45 connector, supporting unshielded twisted-pair (UTP) Cat5e enhanced category 5 cable—balancing cost-effectiveness and signal integrity .
Maximum Distance: Supports a transmission range of up to 100 meters between the VI702 card and a Layer 2 network switch, covering typical industrial facility wiring distances .
Hardware & Power Specifications
Host Interface: Adheres to PCI Express CEM Specification 1.0a (x1 lane, 2.5 GT/s signaling), compatible with PCI Express slots of x1 to x16 (physically fits larger slots without performance loss). It is not compatible with legacy PCI slots .
Power Supply: Operates on a 3.3 V DC power supply (with ±9% voltage tolerance) directly from the host PC’s PCI Express slot, eliminating the need for external power .
Power Consumption: Maximum current draw of 2.5 A, translating to low power usage that avoids overloading host system power supplies .
Compatibility
System Compatibility: Fully integrated with Yokogawa CENTUM VP and ProSafe-RS DCS platforms, and serves as a direct replacement for the legacy VI701 card .
Interoperability: VI702 and VI701 cards can coexist on the same Vnet/IP bus, and share identical configuration methods for domain and station numbers—simplifying upgrades in mixed-system environments .
