The Yokogawa VI702 serves as the primary communication gateway for Centum VP stations, facilitating seamless data exchange across the Vnet/IP network. Specifically, this card functions as the direct hardware replacement for the legacy VI701 model, offering improved reliability and modern bus compatibility. Because it utilizes the PCI Express (PCIe) architecture, the card integrates easily into standard workstation slots from x1 to x16. Furthermore, the 1 Gbps transmission speed ensures that high-priority control signals travel across the plant network with minimal latency.
Regarding connectivity, the module strictly adheres to the 1000BASE-T standard for reliable gigabit performance. Specifically, the card uses a standard RJ45 connector to interface with CAT5e (Enhanced Category 5) unshielded twisted-pair cables. This setup allows for a maximum distance of 100 meters between the Yokogawa VI702 and the nearest Layer 2 switch. Meanwhile, the full-duplex communication mode prevents data collisions, which is essential for maintaining the deterministic timing required in process automation.
The Yokogawa VI702 features a set of front-facing LED indicators that allow technicians to verify the link status at a glance. For instance, the RDY lamp glows when internal diagnostics confirm the card is operational, while the RCV and SND lamps flash during active data transmission. In terms of power, the card draws a maximum of 2.5 A from the 3.3 V PCIe power rail. Despite its high processing power, the module remains lightweight at approximately 0.18 kg, ensuring it does not place physical stress on the motherboard slot.
First, ensure the workstation is powered down and that you have taken appropriate anti-static precautions before opening the chassis. Next, locate an available PCI Express slot (x1, x4, x8, or x16) and firmly seat the Yokogawa VI702 into the connector. After that, secure the mounting bracket with the retaining screw to provide a solid ground and prevent the card from shifting. Finally, connect the CAT5e cable to the RJ45 port and power on the system to verify the RDY lamp lights up, indicating a successful hardware initialization.

Q: Can I install the VI702 in a traditional PCI slot? No, the Yokogawa VI702 is strictly a PCI Express (PCIe) card and is physically incompatible with older PCI slots.
Q: Is the VI702 compatible with software designed for the VI701? Specifically, the Yokogawa VI702 is the official replacement for the VI701 and maintains full functional compatibility within the Centum VP environment.
Q: What cable type does the card require for 1 Gbps speeds? The card requires CAT5e (Enhanced Category 5) or higher rated UTP cables to support 1000BASE-T transmission.
Q: What do the RCV and SND lamps indicate? The RCV lamp indicates the card is detecting incoming signals from the bus, while the SND lamp indicates the card is transmitting data.
Q: What is the maximum distance for a single cable segment? The maximum distance between the Yokogawa VI702 and the Layer 2 network switch is 100 meters per segment.
