Compatibility & Replacement
Yokogawa Field Control Unit
CP461 is documented for compatible CENTUM Field Control Unit configurations, including AFV30S and AFV30D. AFV30S-S and AFV30D-S are the CP461 configurations.
CP461-10 → CP461-50
CP461-50 is identified as a replacement for CP461-10 in available product documentation.
CP471 migration: Yokogawa documents CP471 as the replacement path for existing CP461 installations. This replacement requires a Yokogawa-authorized service engineer.
Application & Fault Scenarios
Processor layer of the Field Control Station
The module operates within the Field Control Unit control layer and works with the CENTUM VP FCU, Vnet/IP, ESB bus and connected I/O or node units.
Common replacement needs
Existing CP461 replacement, redundant-pair spares and planned maintenance are typical reasons to source this processor.
Maintenance impact: A processor fault can affect the control layer. Actual plant impact depends on the available redundant processor and the configured control strategy.
Redundancy, Bus & Installation
Processor redundancy
A duplexed FCU uses two identical CP461 processor modules with the same model code.
ESB bus coupling
- EC401 or EC402 for ESB Bus Node Units.
- Both designated positions are used for processor redundancy.
- Single ESB configurations use the designated single position.
Optical ESB
ANT401 or ANT411 is used for optical ESB remote connections where required.
FCU connections
- M4 screw terminals for power, grounding and READY contact.
- CAT5e or better UTP for the network connection.
System Configuration Notes
AFV30 is a 19-inch rack-mountable Field Control Unit for FIO.
Up to 13 ESB Bus Node Units and Optical ESB Bus Node Units can be connected per FCU.
The host FCU provides battery-backed main-memory protection for up to 72 hours.
Delivery, Warranty & RFQ
Testing: Functional inspection before shipment.
Packaging: Protective industrial packaging.
Warranty: 12 months under agreed warranty terms.
DOA: Arrival damage or initial failure can be reported with supporting evidence.
Returns: Handled according to the agreed order and warranty conditions.
