Product Overview

The Yokogawa AFV10D is a high-availability Duplexed Field Control Unit (FCU) designed as the core processing engine for the CENTUM VP Distributed Control System. This unit is specifically engineered to execute complex regulatory control, sequence control, and data management tasks with high-speed reliability. By utilizing a dual-redundant processor configuration, the AFV10D ensures that control is maintained without interruption; in the event of a hardware fault on the primary processor, the standby unit takes over control bumplessly.

Communicating via the high-speed Vnet/IP control network, the AFV10D serves as the central hub for field signals processed through I/O modules. Its architecture is optimized for large-scale industrial plants requiring maximum uptime, providing a stable platform for mission-critical logic execution and seamless integration with Human Interface Stations (HIS).

Core Functionality and System Benefits

• Fault-Tolerant Redundancy: The duplexed design eliminates single points of failure within the controller, making it essential for processes where shutdown is not an option.

• Vnet/IP Integration: Utilizes standard Ethernet-based technology for the control bus, allowing for rapid data exchange and easier synchronization across the DCS network.

• High-Speed Logic Execution: Equipped with a powerful microprocessor capable of handling intensive computational loads, ensuring precise control over fast-acting process variables.

• Maintenance and Scalability: Supports online hardware replacement and expansion. The unit is designed for long-term lifecycle support within the CENTUM VP ecosystem, despite its legacy status in newer installations.

• Industrial Grade Build: Constructed to withstand electrical noise and vibration, meeting international standards for safety and electromagnetic compatibility (EMC).
