FOUNDATION Fieldbus Solution – YOKOGAWA NFBU200-S00 | CENTUM VP / ProSafe Series
Where This Product Is Used
The YOKOGAWA NFBU200-S00 Fieldbus Communication Module is engineered for demanding process automation environments where reliable, deterministic field device communication is critical. Typical deployment scenarios include:
- Oil & Gas Upstream/Downstream: Connecting HART and FOUNDATION Fieldbus instruments (flow transmitters, pressure sensors, control valves) in wellhead control panels and refinery DCS cabinets.
- Chemical & Petrochemical Plants: Integrating multi-drop fieldbus segments for reactor monitoring, distillation column control, and safety instrumented systems (SIS).
- Power Generation: Boiler management systems and turbine control loops requiring high-speed, noise-immune digital communication.
- Pulp & Paper / Water Treatment: Distributed I/O architectures where long cable runs demand robust fieldbus topology over traditional 4–20 mA wiring.
- Pharmaceutical Manufacturing: FDA-compliant process control networks with full device diagnostics and audit trail support via FOUNDATION Fieldbus.

Why Engineers Specify This Model
- Native CENTUM VP Integration: Plug-and-play compatibility with YOKOGAWA’s CENTUM VP FCS (Field Control Station) eliminates custom driver development and reduces commissioning time.
- Deterministic Communication: FOUNDATION Fieldbus H1 guarantees cycle-time consistency critical for closed-loop PID control executed at the field device level.
- Advanced Device Diagnostics: Supports NAMUR NE 107 condition monitoring, enabling predictive maintenance and reducing unplanned shutdowns.
- Segment Redundancy Options: Compatible with redundant fieldbus coupler configurations for SIL-rated loops.
- Reduced Wiring Cost: Multi-drop topology (up to 32 devices per segment) significantly cuts cable, conduit, and I/O card costs versus conventional analog wiring.
- Long-Term Availability: YOKOGAWA’s global spare parts program ensures module availability for the full plant lifecycle (20+ years).

Application-Specific FAQ
Q: Is the NFBU200-S00 compatible with CENTUM CS 3000?
A: The NFBU200-S00 is designed for the CENTUM VP platform. For CS 3000 systems, please consult YOKOGAWA’s compatibility matrix or contact us — we can source the appropriate legacy module.
Q: Can this module be used in a SIL 2 safety loop?
A: When integrated within a certified ProSafe-RS architecture and paired with SIL-rated field devices, the fieldbus segment can support SIL 2 applications. Always verify with your functional safety engineer and the YOKOGAWA SIL certificate documentation.
Q: What is the maximum number of field devices per H1 segment?
A: FOUNDATION Fieldbus H1 supports up to 32 devices per segment; however, practical installations typically limit segments to 8–16 devices to maintain adequate bus power and cycle time margins.
Q: Do you provide the YOKOGAWA device description (DD) files?
A: DD files are available from the YOKOGAWA FieldMate / PRM library. We can assist in locating the correct DD version for your host system upon request.
Q: What warranty does Konmask.com provide?
A: We offer a 90-day functional warranty on all modules. Extended warranty and exchange programs are available for long-term MRO contracts.
