Product Description
The VF701 S2 is a high-speed Vnet/IP network interface card that integrates PC-based stations—such as Human Interface Stations (HIS) or Engineering Stations (ENG)—into the Yokogawa CENTUM VP or ProSafe-RS control networks.
Built on PCI Express (PCIe) architecture, this card serves as a redundant, deterministic communication gateway, ensuring real-time, uninterrupted data exchange. The S2 revision provides enhanced hardware performance for low-latency operation and industrial-grade reliability, supporting continuous 24/7 plant operations.
