Product Overview
The AFV30D-A41252/HKU is a high-performance Field Control Unit (FCU) designed for the Yokogawa CENTUM VP integrated production control system. This model features a duplexed architecture, providing high availability for mission-critical industrial processes. It is optimized for 19-inch rack mounting and supports high-speed Vnet/IP communication protocols for seamless plant-wide network integration.
The /HKU option adds a Housekeeping Unit (HKU), which continuously monitors internal cabinet conditions such as temperature, fan status, and door contact alarms, enhancing system reliability by preventing thermal-related hardware failures.

Functional Comparison: AFV30D vs. AFV30S
The AFV30D-A41252/HKU (Duplexed) differs from the AFV30S (Single) model in terms of failure tolerance.
-
AFV30D-A41252/HKU ensures bumpless transfer to the secondary module in case of processor or power supply failure, preserving real-time data and maintaining process continuity without a reset.
-
AFV30S, being a single-processor unit, is suitable for non-critical control loops and does not offer the same level of redundancy.
Implementation FAQ
What is the specific benefit of the /HKU suffix on this model?
The /HKU suffix integrates a Housekeeping Unit that monitors the internal environment of the control cabinet. It can trigger alarms in the CENTUM VP Human Interface Station (HIS) if critical conditions like fan failure or excessive temperature are detected. This helps prevent thermal damage to the hardware and ensures stable long-term operation.
How is redundancy handled for the network layer?
The unit includes dual-redundant Vnet/IP ports. In case of a cable break or failure in one communication path, the AFV30D-A41252/HKU automatically switches all control traffic to the healthy network path without requiring intervention from the application layer. This ensures continuous data flow and uninterrupted communication.
