The Yokogawa AVR10D-Q22020 is a high-performance, dual-redundant V-net router designed to act as a critical bridge between disparate CENTUM control system segments. It facilitates seamless data exchange, ensuring deterministic communication across industrial network architectures.

Hardware Specifications

Industrial Network and Data Connectivity

The AVR10D serves as a gateway that maintains network integrity through dual-redundancy. By supporting both 10BASE-2 (Vnet) and 100 Mbps Ethernet (Vnet/IP) standards, it allows for legacy system integration alongside modern high-speed control networks. The router employs high-speed backplane bus communication to manage packet routing with minimal latency, ensuring that control data remains synchronized across redundant segments.

Frequently Asked Questions

Q: Does the dual power supply configuration support hot-swapping?

A: Yes. The unit is designed with dual power supplies to ensure continuous operation. If one power supply unit fails, the system automatically draws from the second unit without interrupting the network routing functions.

Q: Is the RJ45 Vnet/IP interface compatible with standard commercial-grade switches?

A: While the interface utilizes standard physical layer connectivity, it is optimized for Yokogawa control protocols. It is strongly recommended to use managed industrial-grade switches that support the required frame prioritization (QoS) for deterministic data traffic.

Field Installation Guidelines

• Mechanical Installation: The unit should be mounted in a standard 19-inch rack or on a flat cabinet panel. Ensure the 80 mm depth is respected to allow for cable clearance and adequate airflow.
• Redundancy Setup: For the Vnet redundancy to function, both BNC ports must be connected to distinct network segments. Verify that the system configuration software acknowledges both paths as active before putting the router into service.
• Grounding Requirements: Securely bond the chassis ground screw to the cabinet's protective earth (PE) bus. Because this device handles high-speed communication signals, a low-impedance ground is vital to prevent electromagnetic interference (EMI) from inducing errors in the Vnet packets.
• Cable Management: Utilize BNC T-connectors for the Vnet side and Cat5e or Cat6 shielded twisted-pair cables for the Vnet/IP side. Do not exceed 185 meters for the 10BASE-2 segment to avoid signal attenuation.
