System compatibility

Designed for Yokogawa CENTUM VP DCS,installed in AFV30S single FCS or AFV30D dual redundant FCS field control station,compatible with FIO/N-IO I/O modules,widely used in petrochemical,power,chemical refining process control.

Function

CP461-50 is high-performance core processor module of FCS field control station.It executes real-time PID control,interlock logic,sequence batch control,alarm management and historical data collection.It communicates with HIS operator station,engineering station and remote I/O modules via high-speed Vnet/IP bus.Dual CP461-50 can form redundant configuration,standby module synchronizes data in real-time,switch over without disturbance when main CPU fails.The -50 suffix represents standard non-ex-proof model for ordinary industrial areas.

Installation

Install on FCS chassis backplane slot,connect Vnet/IP network cable to dual Gigabit Ethernet ports,configure control strategy and redundancy parameters via CENTUM VP engineering software.Hot swap supported under redundant configuration.

Interface

‑Dual 1Gbps Vnet/IP RJ45 ethernet ports

‑RS232C service debug port

‑USB maintenance port

‑Internal ESB bus backplane connector

‑LED indicators for run,standby,alarm and fault status

Circuit feature

ECC error correction memory,hardware watchdog circuit,continuous hardware self-diagnosis,galvanic isolation on network ports,strong anti-electromagnetic interference,stable for continuous long-term operation.

Feature

CP461-50 belongs to Yokogawa CENTUM VP high-performance FCS processor series.Suffix -50 is standard version without explosion protection.Common faults:backup battery aging,network port damage,memory failure,backplane poor contact.Confirm firmware version before replacement.

Diagnostic

CPU error,memory fault,communication link loss or module hardware fault triggers alarm and upload diagnostic information to DCS HIS station.

Built‑in function

Real-time process control,logic interlock,alarm processing and system communication management for DCS field control station,used for industrial DCS spare replacement.

Product Brief

CP461-50 is Yokogawa CENTUM VP FCS high-performance RISC processor module,standard non-ex-proof version,supports 1:1 hot standby bumpless switchover.Check FCS chassis model and system firmware compatibility before ordering.ESD anti-static protection required during installation.
