LED Status & Diagnostics
- RDY (Ready) – Lights when the card passes self-diagnosis.
- RCV (Receive) – Lights when the card detects control bus signals.
- SND (Send) – Lights during active signal transmission on the control bus.
Diagnostic capability: Onboard LEDs provide instant health and activity feedback. The RDY lamp confirms normal operation. RCV and SND lamps verify network traffic. This simplifies troubleshooting and reduces downtime.
Installation & Compatibility
- Installation: Insert the VI702 into any PCI Express slot (x1 to x16). Do not install in a PCI slot. Use a CAT5e UTP cable for Ethernet connection. Ensure the distance to the Layer 2 switch does not exceed 100 m.
- Compatibility: The VI702 replaces the VI701 directly. It supports Yokogawa CENTUM VP and CS 3000 systems. It also integrates with Modicon Quantum series via Vnet/IP gateway.
- Maintenance & debugging: No special tools required. LED indicators enable fast debugging. The card supports hot-swap in compatible chassis (check system manual). Firmware is field-upgradable via the PCIe interface.
Environmental & Mechanical Resilience
- Temperature range: 0 to 55 °C (operational).
- Storage temperature: -20 to 70 °C.
