Configured for deterministic data routing within V net control networks, the YOKOGAWA AVR10D-A22040 (AVR10D Duplexed V net Router) provides direct physical/electrical execution of inter-subnetwork communication and traffic management across DCS platforms.

Suffix Breakdown & Model Matrix

• AVR10D: Base model designation for the duplexed V net router assembly.
• A: Denotes the standard hardware revision and chassis format.
• 22: Specifies the dual-port V net communication interface configuration.
• 040: Identifies the integrated logic firmware version and port-speed compatibility standard.

Hardware Specifications

Process Control and DCS Connectivity

The AVR10D-A22040 maintains high-speed data integrity across distributed control stations by utilizing redundant V net communication channels. The router employs hardware-based channel-to-channel isolation to prevent electrical interference propagation between the V net segments and the local control bus. By managing protocol-specific data packets, the router ensures deterministic latency for real-time process control commands. Cold junction compensation (CJC) is not applicable to this router component; however, internal diagnostic buffers continuously monitor bus signal quality to prevent packet loss during heavy network traffic.

Frequently Asked Questions

Q: Does the AVR10D-A22040 support hot-swapping in a live V net environment?

A: The duplexed configuration allows for the replacement of a single router unit while the system remains operational, provided the standby unit has completed synchronization and the V net segment is stable.

Q: Is external configuration required for the V net addresses?

A: Yes, network addressing and subnetwork routing tables must be configured via the system engineering station to align the router with the existing V net infrastructure.

Field Installation Guidelines

1. Chassis Mounting: Install the unit in a standard control rack. Ensure the mounting brackets are securely fastened to maintain mechanical stability and proper alignment with the V net backplane interface.
2. Earthing and Shielding: Connect the chassis ground terminal to the instrument earth bus using a low-impedance copper strap. Ensure that all V net communication cables utilize shielded connectors to minimize common-mode noise.
3. Redundancy Synchronization: Before enabling the duplexed pair, verify that the firmware versions on both router modules match. Power up the modules sequentially to allow for internal diagnostic self-testing and synchronization.
4. Wiring Segregation: Route V net cables through dedicated, non-conductive cable trays, maintaining separation from high-voltage lines to prevent electromagnetic interference (EMI) ingress.
