Product Description
The VF702 S1 is a high-performance communication interface card that connects PC/AT-compatible workstations (HIS/ENG) to the Yokogawa V net control bus. Designed for legacy and specialized CENTUM systems, it provides a deterministic, coaxial-based communication path for reliable process data exchange.
Built on PCI Express (PCIe), the VF702 S1 supports modern workstation integration while maintaining compatibility with 10BASE-2 coaxial networks, making it ideal for upgrading or extending existing V net infrastructures.
