Function

CS3000 DCS CPU is the core processor of CENTUM CS3000 FCS field control station.It adopts Yokogawa unique Pair & Spare technology,two MPUs run same calculation and cross-check results to detect transient errors.It executes real-time PID control,interlock logic,sequence batch control,alarm management and trend data collection.Communicate with HIS operator station,engineering station and remote I/O modules via V-Net bus.Dual CPU redundant configuration supports seamless bumpless switchover once main processor fails.

Installation

Install on FCS chassis backplane slot,connect V-Net coaxial cable to network ports,configure control strategy and redundancy parameters via CENTUM CS3000 engineering software.Hot swap supported under redundant configuration.

Interface

‑Dual V-Net communication ports

‑RS232C service debug port

‑Internal backplane bus connector

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

Circuit feature

ECC memory error correction,hardware watchdog,continuous hardware self-diagnosis,galvanic isolation for network interface,strong anti-electromagnetic interference,suitable for long-term uninterrupted industrial operation.

Feature
