Yokogawa AFV30S-S41151 Single Field Control Unit

Overview

The Yokogawa AFV30S‑S41151 is a high‑performance single Field Control Unit (FCU) for CENTUM VP distributed control systems. Designed as the central processor for a Field Control Station (FCS), it executes regulatory, sequence, logic, and batch control functions with deterministic cycle timing, ensuring reliable and continuous plant operation. Unlike duplexed FCUs (AFV30D), this model operates as a standalone unit without CPU redundancy.

This FCU communicates via the Vnet/IP real‑time network and is engineered for demanding industries such as oil & gas, petrochemical, chemical, and power generation. Its industrial‑grade construction ensures long-term stability in high-noise environments.

FAQ

Q: Can AFV30S‑S41151 be upgraded to duplex mode?
A: No, this model is strictly a single CPU unit. For duplex redundancy, AFV30D models are required.

Q: What type of network does this FCU support?
A: Vnet/IP real-time control network for deterministic communication with I/O modules.
