CP345 S1 is a Yokogawa processor-card identifier for legacy CENTUM CS 3000 field control station maintenance. The host FCU, control-function license and installed hardware style determine the replacement check.
Application guidance: CENTUM CS 3000 maintenance. Like-for-like maintenance of the documented CP345 S1 installation. Spare and migration review using the full installed-system record.
Ordering note: Reproduce CP345 S1 exactly and confirm the installed hardware, terminal arrangement, project release and site requirements.
| Manufacturer | Yokogawa Electric Corporation |
|---|---|
| Full part number | CP345 S1 |
| Hardware style | S1 as specified |
| Component role | FCS processor card |
| Control-network context | V-net, according to host FCU |
| Host examples | Documented AFG and AFS families |
| Memory selection | Station dependent; do not infer one capacity from CP345 alone |
Before CP345 S1 replacement, retain the approved configuration and follow the applicable host maintenance and commissioning procedure. Verify the complete hardware and software combination before migration.
CP345 S1 belongs to the CP345 processor-card family documented for CENTUM CS 3000 field control stations; confirm the specific AFG or AFS host.
No. CP345 S1 selection must include the host FCU: Yokogawa documents different station memory capacities for AFS and AFG variants.
Check CP345 S1 against the existing V-net station and I/O-bus configuration; a modern Vnet/IP processor is not established as a direct card replacement.
For CP345 S1, record the host station's control-function package and software release; the documented RIO station variants specify LFS1100 or LFS1130 and release conditions.
Check the approved FCU fan configuration for CP345 S1. Yokogawa's AIP601 S2 applicability list contains specific legacy V-net stations with CP345 installed.
CP401 reused CP345 architecture in a different modular FFCS design; that design history does not establish a direct physical substitution for CP345 S1.
Specify CP345 S1, host FCU, full label photographs, installed firmware and required pairing details so the replacement can be checked against the station records.
Send the exact CP345 S1 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.
