Product Description

The VI701 is a high-performance network interface card (NIC) designed specifically for the Yokogawa Vnet/IP real-time control network. It enables industrial workstations and servers to connect directly to Yokogawa control systems, providing the deterministic communication performance required in advanced automation environments.

Using a standard PCI bus interface, the VI701 allows industrial PCs, engineering stations, and operator workstations to integrate seamlessly into the Yokogawa control infrastructure. The card delivers full-duplex Gigabit Ethernet connectivity, ensuring high-bandwidth data exchange between controllers, servers, and human-machine interfaces (HMIs) with minimal latency.

Optimized for industrial reliability, the VI701 supports auto-negotiation for speed and duplex mode, ensuring stable communication across Ethernet networks. It is a critical communication component in systems where continuous monitoring, real-time data logging, and supervisory control are essential for plant operation.

Technical Specifications

Field Applications

The VI701 is a core communication component used in Yokogawa CENTUM VP and ProSafe-RS system architectures. It is typically installed in industrial PCs, HMI workstations, or system servers that require direct connectivity to the Vnet/IP control network.

Common application roles include:

• Operator station communication within distributed control systems

• Real-time process monitoring and supervisory control

• Industrial data logging and historian servers

• Engineering workstation access to field controllers

By providing high-speed and deterministic network communication, the VI701 ensures reliable data transfer between control-layer infrastructure and distributed field controllers.

Frequently Asked Questions

Can the VI701 be installed in a standard PCI-X slot?
Yes. The card is physically and electrically compatible with PCI-X slots. When installed in such slots, it will automatically operate at the standard 33 MHz PCI bus speed to maintain compatibility.

Does the VI701 require special drivers?
Yes. As a specialized industrial communication card, the VI701 requires dedicated Yokogawa Vnet/IP driver software installed on the host operating system to correctly manage deterministic communication protocols within the control network.
