Product Overview

The S2CP471-01 S1 is a high-reliability central processing unit (CPU) for the Yokogawa CENTUM VP Distributed Control System (DCS). It functions as the primary computational engine within Field Control Stations (FCS) and is specifically optimized for AFV30 and AFV40 Field Control Units.

Designed for high-speed logic execution, the S2CP471-01 S1 efficiently manages complex PID control, sequence logic, and high-density data acquisition. Its advanced RISC architecture combined with ECC-protected memory ensures deterministic control performance and maximum system availability in demanding industries such as petrochemicals and power generation.

Technical Specifications

System Features & Benefits

• Seamless Redundancy: In duplex configurations, automatic and bumpless transfer occurs if the active CPU fails

• High Throughput: Optimized for large-scale systems with fast scan times across thousands of I/O points

• Reliability & Diagnostics: Continuous self-diagnostics monitor hardware status and memory integrity

• Industrial Robustness: Designed to meet industrial requirements for vibration resistance and EMC compliance

FAQ

What is the difference between CP471 and S2CP471-01 S1?
The “S2” prefix typically indicates a variant intended for specific Field Control Unit platforms or enhanced communication/safety integration within the CENTUM VP ecosystem, while retaining the core CP471 processing architecture.

Is the S2CP471-01 S1 compatible with CENTUM CS 3000?
This module is primarily designed for CENTUM VP. Compatibility with CS 3000 depends on the FCU base plate hardware revision and the installed system software (ENG) version.
