Yokogawa CP471-01 CENTUM VP Processor Module
A no-explosion-protection CP471 processor execution with the ISA Standard G3 option for supported CENTUM field control units.
Overview
CP471-01 is a Yokogawa processor module for CENTUM field control units. Its first suffix digit specifies no explosion protection, and the second digit selects the ISA Standard G3 option.
Two CP471 modules may be installed in a dual-redundant configuration on a duplexed field control unit. Compatibility depends on the FCU model code, CENTUM VP release and the associated EC401 style where that bus coupler is used.

Features
Processor module designed specifically for supported CENTUM field control units.
ISA Standard G3 execution supports the corresponding environmental requirement.
Dual-redundant deployment is available in the documented duplexed FCU arrangement.
Manufacturer-defined software and chassis rules control CP461 migration.
Applications
- CENTUM VP field control stations requiring the CP471-01 environmental execution.
- Duplexed FCS maintenance where processor redundancy must be preserved.
- Authorized upgrades from CP461 after FCU, software and bus-coupler qualification.
Lifecycle
- Record the complete FCU code, CENTUM release, patches, EC401 style and redundancy state.
- Back up the control database and preserve network, time and diagnostic records.
- Follow Yokogawa service requirements for CP461-to-CP471 migration rather than treating it as an unrestricted user exchange.
- After work, verify both processor states, synchronization, FCS communications, I/O health and application control.
FAQ
Why is the complete FCU code required when quoting CP471-01?
The applicable processor suffix depends on the field control unit family and its own model-code positions.
Can CP471-01 replace CP461 without a migration review?
No. Yokogawa documents specific FCU, software, patch and authorized-service conditions for the migration.
What does the 01 suffix mean on CP471-01?
It identifies no explosion protection together with the ISA Standard G3 option.
Which software evidence should accompany CP471-01?
Provide the CENTUM VP release, installed support patches, FCS control-function version and database backup.
What should be tested after installing CP471-01 in a duplexed FCU?
Verify processor synchronization, switchover readiness, Vnet/IP health, I/O status, diagnostics and application control.
