The CP401-11 (Style S1) is a high-performance Field Control Station (FCS) processor module designed for the Yokogawa CENTUM VP and ProSafe-RS control architectures. As the central intelligence unit, the CP401-11 (Part Number: C2KC03014H) executes complex control strategies, manages high-speed Vnet/IP communication, and coordinates data exchange with I/O subsystems.
Engineered for mission-critical reliability, this module utilizes a dual-microprocessor "Pair & Spare" architecture. This design enables the CP401-11 to achieve Safety Integrity Level 3 (SIL3) compliance according to IEC 61508 standards, ensuring continuous operation even in the event of internal hardware faults. Its deterministic processing capabilities make it a staple in global power generation, oil and gas refining, and petrochemical facilities where unplanned downtime is not an option.
The CP401-11 (Model: CP401-11) is built for high-availability process automation and functional safety.
