YOKOGAWA VI702

YOKOGAWA VI702

The YOKOGAWA VI702 is a highperformance Vnet/IP interface card engineered by Yokogawa Electric to deliver reliable, lowlatency Ethernet connectivity for CENTUM VP Distributed Control Systems (DCS). Designed for installation in industrial PCs and workstations (HIS), it acts as a critical bridge between the PCI Express bus and Yokogawa’s proprietary Vnet/IP realtime control network, ensuring seamless, highspeed data exchange for monitoring, control, and safety applications in process industries.

Model Code Explanation: YOKOGAWA VI702

Yokogawa’s VI702 model follows a clear naming convention for easy identification and selection:

• VI: Vnet/IP Interface (dedicated communication card for Yokogawa’s control network)
• 702: Base model number (2ndgeneration gigabit Vnet/IP card, PCIe form factor)
• Optional Suffix (e.g., S1):

• S: Standard industrial grade
• 1: Hardware revision 1, compliant with latest CENTUM VP firmware

Full Meaning: YOKOGAWA VI702 = Vnet/IP Gigabit Ethernet Interface Card, PCIe, 1 Gbps, for CENTUM VP DCS.
