Runs the field control application in the supported CENTUM VP FCU.
Product Overview
CP471-00 is a Yokogawa processor module used in supported CENTUM VP field control units. The first suffix zero specifies no explosion protection and the second zero specifies the basic type.
Two CP471 modules can be used in a dual-redundant configuration on a duplexed FCU. Selection depends on the complete FCU model, CENTUM release, support patches and any associated EC401 style.
Performance
Supports a paired processor arrangement in a documented duplexed controller.
Maintains processor synchronization and role management through the FCU architecture.
Provides the migration target for certain CP461 installations only under Yokogawa-defined conditions.
Technical Details
| Manufacturer | Yokogawa Electric Corporation |
|---|---|
| Exact Model | CP471-00 |
| Product Type | CENTUM VP processor module |
| Explosion-Protection Code | 0: no explosion protection |
| Environmental Code | 0: basic type |
| ISA Standard G3 | Not selected; CP471-01 is the G3 execution |
| Redundancy | Two modules can be dual redundant on a duplexed FCU |
| Supported FCU Families | AFV30S/D, AFV40S/D, A2FV50S/D and A2FV70S/D subject to exact suffix rules |
| Software Baseline | CENTUM VP Control Function for FCS release support must be confirmed |
| ESB Coupler Boundary | EC401 style S3 or later where the documented combination is used |
| Migration Boundary | CP461 replacement requires the documented FCU, software and service conditions |
| Selection Record | FCU model, processor pair, software release, patches and network identity |
System Integration
- Record the complete FCU model code, installed CP471 partner, CENTUM VP release and support patches.
- Back up the engineering database, tuning parameters, network information and controller status.
- Verify the EC401 style and all chassis suffix rules before installing CP471-00.
- For a CP461 migration, follow the prescribed Yokogawa service path rather than treating the change as unrestricted.
- Test synchronization, switchover, I/O health, control execution and alarms after restoration.
Applications
- Replacement in a supported basic-type CENTUM VP field control unit.
- Maintenance of a duplexed FCS while preserving processor redundancy.
- Controlled CP461-to-CP471 migration after hardware and software qualification.
FAQ
Why does a CP471-00 enquiry require the FCU model code?
The applicable processor execution and migration rules depend on the complete field control unit family and suffixes.
Can CP471-00 replace CP471-01?
Not as an automatic substitute. CP471-01 selects ISA Standard G3, while CP471-00 is the basic type.
What must be checked before pairing two CP471-00 modules?
Confirm matching processor revisions, FCU duplex hardware, CENTUM release and patches, database equality and synchronized status.
Can CP471-00 replace CP461 during a short outage?
Only after the documented Yokogawa migration conditions, FCU hardware, software baseline and authorized procedure are satisfied.
What should be in the CP471-00 commissioning record?
Include processor identities, software and patch levels, sync state, switchover test, network health, I/O status and restored application checks.
