Features:
- CP451 processor-module execution for AFV10S and AFV10D Field Control Units.
- Yokogawa specifies two CP451 modules for a dual-redundant processor configuration.
- The documented FCU platform uses dual-redundant Vnet/IP and supports ESB and ER bus node units.
CP451-50 S2 is a Yokogawa CENTUM VP processor-module execution for AFV10S or AFV10D Field Control Units. Yokogawa identifies CP451 as the processor for this FCU family; the official host specification lists a VR5432 processor, 32 Mbyte main memory, battery-backed memory and dual-redundant Vnet/IP. The complete CP451-50 and Style S2 identity must remain with the controlled system record.
Before replacement, record both processor labels, rack positions, redundancy status, AFV10 host model, Vnet/IP settings, ESB and ER bus node layout, CENTUM VP release, control package, battery condition and current diagnostics. Preserve the approved project and recovery media. After installation, verify processor synchronization, network communication, node-unit communication, alarms and every affected process-control loop under the site commissioning procedure.
The CP451-50 S2 Yokogawa CENTUM VP processor module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Yokogawa CP451-50 S2 documentation and reference links.
Important Notice: Confirm the complete order identity, hardware execution, receiving-system configuration and required document revision before replacement.
Yokogawa documents the AFV10S/AFV10D controller platform with a VR5432 processor, 32 Mbyte main memory, battery-backed memory and a dual-redundant Vnet/IP interface. Two CP451 modules are used when the processor configuration is dual redundant.
Use CP451-50 S2 only after confirming the AFV10S or AFV10D host, CENTUM VP release, installed control package, Vnet/IP design, ESB and ER bus interfaces and every connected node-unit limit. A nearby CP451 suffix is not assumed interchangeable.
Restore the approved project and recovery data, verify processor synchronization, battery and diagnostics, then prove Vnet/IP, ESB and ER bus communication and every affected process-control loop before returning the FCU to service.
