YOKOGAWA AFV10D S2 — Duplexed Field Control Unit | CENTUM VP / CS 3000 Platform
Engineering Background
The AFV10D S2 is YOKOGAWA’s duplexed (redundant) Field Control Unit designed for mission-critical process automation within the CENTUM VP and CS 3000 Distributed Control System platforms. Engineered for continuous operation in high-availability environments, this unit provides seamless bumpless switchover between primary and secondary controllers, ensuring zero process interruption during fault events.
Product Positioning
Targeted at process engineers and automation architects in oil & gas, petrochemical, power generation, and advanced manufacturing, the AFV10D S2 delivers the redundancy and deterministic control performance demanded by SIL-rated and high-uptime production environments. It is a direct replacement and upgrade path for legacy CS 3000 FCU installations.

Proven Application Environments
- Oil & Gas: Upstream wellhead automation, midstream pipeline SCADA integration, downstream refinery DCS backbone
- Petrochemical & Chemical: Continuous reactor control, distillation column sequencing, batch process management
- Power Generation: Boiler management systems, turbine control, load-following automation
- Pulp & Paper / Pharmaceuticals: High-availability production lines requiring redundant control with audit-trail compliance
- Water & Wastewater: Multi-station distributed control with centralized SCADA supervision
Engineering Advantages
- True Hardware Redundancy: Dual CPU modules operate in hot-standby mode; switchover is transparent to the process with no control gap
- Deterministic Scan Cycle: Guaranteed real-time response ensures loop integrity even under peak I/O load
- Backward Compatibility: Drop-in compatible with CS 3000 FCU installations; simplifies brownfield upgrades without full system replacement
- Integrated Diagnostics: Self-monitoring with fault isolation reporting to CENTUM VP HIS (Human Interface Station)
- Scalable I/O Architecture: Supports YOKOGAWA’s full range of analog, digital, and FOUNDATION Fieldbus I/O modules
- Long Product Lifecycle: YOKOGAWA’s extended support commitment reduces obsolescence risk for long-horizon plant assets
System Architecture & Signal Flow
The AFV10D S2 mounts in a YOKOGAWA FCU node cabinet and connects to the plant-wide V-net/ER control bus. Each duplexed unit comprises two synchronized CPU boards sharing a common I/O backplane. The primary CPU executes the control strategy; the secondary CPU mirrors all process data in real time. Upon detection of a primary fault (hardware failure, watchdog timeout, or communication loss), the secondary assumes control within one scan cycle. Field signals flow from I/O modules → backplane → active CPU → V-net → HIS/ENG stations, with the standby CPU maintaining a live shadow of all register values.

Technical FAQ
Q: Is the AFV10D S2 compatible with CENTUM VP R6.xx?
A: Yes. The AFV10D S2 is supported under CENTUM VP R4 through R6 with appropriate firmware. Confirm your system revision with our technical team before ordering.
Q: Can this unit replace an AFV10D (non-S2 suffix) directly?
A: The S2 suffix denotes a hardware revision. Physical and electrical compatibility is maintained; however, verify firmware compatibility with your CENTUM VP engineering station before hot-swap replacement.
Q: Do you provide a warranty?
A: All units carry a 90-day functional warranty against DOA defects. Extended warranty options are available — contact us for details.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items are sourced within 2–6 weeks depending on global availability.
Q: Can you supply the full FCU node (cabinet, power supply, I/O modules)?
A: Yes. Konmask.com specializes in complete YOKOGAWA system assemblies. Contact us with your full BOM for a turnkey quotation.
