CP401-10 identifies a Yokogawa CP401 processor module for legacy FFCS maintenance. Confirm the AFF30/AFF50 host, complete suffix and installed configuration before selecting a spare.
Application guidance: FFCS processor maintenance. Like-for-like maintenance of the documented CP401-10 installation. Spare and migration review using the full installed-system record.
Ordering note: Reproduce CP401-10 exactly and confirm the installed hardware, terminal arrangement, project release and site requirements.
| Manufacturer | Yokogawa Electric Corporation |
|---|---|
| Full part number | CP401-10 |
| Host family | AFF30S/D and AFF50S/D |
| Architecture | Pair & Spare processor design |
| Internal processor arrangement | Two MPUs per documented CP401 module |
| Processor equalization | SEN bus |
| Control-network context | V-net FFCS |
| Suffix check | Match -10 to installed module; no suffix equivalence assumed |
Before CP401-10 replacement, retain the approved configuration and follow the applicable host maintenance and commissioning procedure. Verify the complete hardware and software combination before migration.
Yokogawa maps CP401 to AFF30S/D and AFF50S/D; verify the complete host identifier when selecting CP401-10.
The documented CP401 family uses paired MPUs with result comparison. Apply CP401-10 within the approved FFCS redundancy configuration.
In the documented CP401 architecture, the SEN bus copies programs and equalizes data between processors; CP401-10 replacement should preserve the approved pairing configuration.
Review the FFCS V-net coupling and station configuration for CP401-10, along with the separate ESB or ER interface modules used by the installation.
Record the current station configuration and memory-backup battery condition before CP401-10 maintenance, following the applicable station procedure.
A shared CP prefix does not confirm CP401-10 interchangeability; host hardware, buses, firmware and software must be assessed together.
Provide CP401-10, host AFF station model, label photographs, firmware details and whether a single spare or a matched redundant set is required.
Send the exact CP401-10 nameplate, quantity, installed Yokogawa system, terminal hardware, destination and clear photos. Availability, condition and compatibility will be confirmed before quotation.
Verify the cited document revision and its applicability to the complete model, style and installed assembly. Family-level documentation does not establish interchangeability for an unlisted suffix.
