Product Description

The CP461-50 S1 is a mission-critical processing module designed for the Yokogawa CENTUM VP Field Control Station (FCS). It is engineered to execute intensive process control logic while managing high-speed data processing and seamless I/O communication within AFV30S and AFV40S controller systems. Based on a 32-bit RISC architecture, the module delivers deterministic performance suitable for complex automation loops and real-time control tasks.

Designed for high-availability control environments, the CP461-50 S1 supports hot-swappable dual-redundant (duplex) configurations, allowing maintenance or module replacement without interrupting the running process. As an S1 hardware style, this version is optimized for standard industrial environments and is commonly used as a replacement or expansion processor in legacy CENTUM VP installations.

Technical Specifications

Application Scenarios

The CP461-50 S1 is widely deployed in oil refineries, chemical processing plants, and thermal power stations where continuous operation is mandatory. It is well suited for applications involving high-density PID control loops, sequence control, and interlock logic, supporting 24/7 plant operation with minimal downtime.

Frequently Asked Questions

Q: Can the CP461-50 S1 be paired with a CP471 module in a redundant configuration?
A: No. In a dual-redundant configuration, both processor modules must be identical models and hardware styles. CP461-50 S1 and CP471 processors cannot be mixed within the same redundant pair.

Q: Does the CP461-50 S1 require a specific CENTUM VP software version?
A: Yes. The module is generally compatible with CENTUM VP R6.01 or later. Certain advanced functions may require R6.05 or specific Yokogawa-issued software patches.

Q: Can this module be replaced while the system is running?
A: Yes. When configured in a dual-redundant system, a single CP461-50 S1 can be replaced using online replacement without shutting down the controller or interrupting process control.
